SAFETY WARNINGS FOR PROPANE UNITS

CARBON MONOXIDE HAZARD

Burning propane makes Carbon Monoxide (CO). CO is invisible, has no smell and can kill you. Operating your outboard engine in an enclosed area can be dangerous.

1. Use only in well ventilated areas. If you experience headache, drowsiness, or nausea, turn unit o and get fresh air quickly.

2. Never use where people are sleeping.

3. Follow unit instructions for proper use.

HANDLING & STORAGE

1. Keep out of reach of children.

2. Never expose cylinder to heat, sparks, or ame.

Never store in direct sunlight. Never store at temperatures above 120 degrees F

(49° C).

3. Never store in living spaces.

4. Always use cylinder until it is completely empty.

5. Never rell a disposable cylinder. Relling may cause

an explosion. Federal law forbids transportation if relled, a penalty up to $500,000, and 5 years imprisonment (49 U.S.C. 5124).

6. Never store in luggage or take on trains or aircraft.

7. To discard, contact local refuse hauler or recycle center.

Never put in re or incinerator. Do not puncture. If your cylinder was purchased with a “Green Key” * or similar device, install it when empty and cylinder may be recycled with other steel items.

* Green Key- is a trademark of the Coleman company

NOTE: FIRE/EXPLOSION HAZARD

Contains enough gas to cause serious re, explosion, and burns. To reduce chance of leak, re, or explosion, take the following precautions:

BEFORE USE

1. Check cylinder and appliance seals. Never use with damaged or missing seals. Discard cylinder if dirt or rust particles are in valve area.

2. Turn engine o.

3. Attach cylinder outdoors away from pilot lights, ames, sparks or other ignition sources. These sources can ignite leaking gas.

4. Hand tighten only. Never use tools to tighten. Over tightening can damage seals.

5. Check for leaks. Put soapy water on connections. Look for bubbles. Listen for hiss of escaping gas. Feel for extreme cold. Smell for rotten egg odor. Do not use if leaking.

6. Read and follow operation instructions.

DURING USE

Never use near pilot lights, ames, sparks, or other ignition sources. They can ignite leaking gas.

AFTER USE

1. Turn engine o and let cool.

2. Detach cylinder when not in use.

3. Detach outdoors away from pilot lights, ames, sparks,

or other ignition sources, they can ignite leaking gas.

4. Replace cap to keep valve clean.

IN CASE OF FIRE

1. Leave area quickly and call for help.

2. Let the cylinder burn out.

UNDERSTANDING PROPANE

NOTE: Use propane only in containers and/or remote larger tanks specically designed and approved for this unit. Propane is a combustible gas, it is colorless and thus invisible to the naked eye. Propane has a harmless odorant added so that it is possible to smell it. The user should be familiar with the smell of propane (smells like sulfur or rotten eggs). If at any time the smell of propane is identied, turn o the engine. If the leak persists, remove the pro-pane canister. Never attempt to operate a unit that has a suspected leak. Always remove the propane canister from any unit that has a suspected leak.

WARNING:

PROPANE IS HIGHLY FLAMMABLE, AND ITS VAPORS CAN EXPLODE IF IGNITED.

GENERAL INFORMATION

• Before mounting or operating the outboard motor, completely read manual and labels. Reading them will give you a good understanding of the motor and its operation.

• Before operating the boat, read any owner's or operator's manuals supplied with it and all labels. Be sure you understand all items from the boat manual as well as this engine manual before operating.

• Do not over power the boat with this outboard motor. Overpowering the boat could result in damage to the boat and injury to all occupants. The rated power of the outboard should be equal to or less than the rated horsepower capacity of the boat. If the rated horsepower capacity of the boat is unknown, consult the dealer or boat manufacturer.

• Do not attempt to modify the outboard. Modifications could make the motor unsafe to use and will void the warranty. Incorrect propeller selection and incorrect use may not only cause engine damage, but also adversely affect fuel consumption. Consult your dealer for correct use.

• Never operate after drinking alcohol or taking drugs. About 50% of all boating fatalities involve intoxication.

• Have an approved personal flotation device (PFD) on board for every occupant. It is a good idea to wear a PFD whenever boating. Children and non-swimmers should always wear PFD's, and every one should wear PFD's when there are potentially hazardous boating conditions.

• Propane is highly flammable, and its vapors are flammable and explosive. Handle and store propane carefully. Make sure there are no fumes or leaking fuel before starting the engine.

• This product emits exhaust gases which contain carbon monoxide, a colorless, odorless gas which may cause brain damage or death when inhaled. Symptoms include nausea, dizziness, and drowsiness. Keep cockpit and cabin areas well ventilated. Avoid blocking exhaust outlets.

• Check throttle, shift, and steering for proper operation before starting the engine.

• Attach the engine stop switch lanyard cord to a secure place on your clothing, or your arm or leg while operating. If you accidentally leave the helm, the cord will pull from the switch, stopping the engine.

• Know the marine laws and regulations where you will be boating and obey them.

• Know about the weather forecast. Check weather before boating. Avoid boating in hazardous weather.

• Tell some one where you are going: leave a Float Plan with a responsible person. Be sure to cancel the Float Plan when you return.

• Be aware, alert, and use good judgment when boating. Know your abilities, and be familiar with how your boat handles under the different boating conditions you may encounter. Operate within your limits, and the limits of your boat. Always operate at safe speeds, and watch carefully for obstacles and other traffic.

• Always watch carefully for swimmers.

• Stay away from swimming areas.

• When a swimmer is in the water near you shift into neutral and shut off the engine.

• Do not illegally discard empty containers used to replace or replenish oil. For the correct processing of empty containers ,consult the dealer where you purchased the oil.

• When replacing oils used to lubricate the product (engine or gear oil), be sure to wipe away any spilled oil. Never pour oil without using a funnel or similar device. If necessary, verify the necessary replacement procedure with the dealer.

• Never illegally discard (dump) disposable propane tanks. Consult your local city recycling center on discarding empty propane tanks.

GENERAL INFORMATION

WARNING: Do not overt ighten the throttle friction adjuster. If there is too much resistance, it could be difficult to move throttle lever or grip, which could result in an accident. When constant speed is desired, tighten the adjuster just enough to maintain the desired throttle setting.

ENGINE STOP SWITCH

The engine stop switch lock must be attac hed to the engine stop switch for the engine to run. The hook should be attached to a secure place on the operators clothing, or arm or leg. Should the operator fall over board or leave the helm, the hook will pull out the stop switch lock, stopping ignition to the engine. This will prevent the boat from running away under power.

WARNING: Attach the engine st op switch hook to a secure place on your clothing, or your arm or leg while operating. Do not attach the hook to clothing that could tear loose. Do not rout e the

lanyard where it could be come entangled, preventing it from functioning. Avoid a ccidentally pulling the lanyard during normal operation. Los s of engine power means the loss o f most steering control. Also, without engine power, the boat could slow rapidly. This could cause people and objects in the boat to be thrown forward.

NOTE: The engine cannot be started wit h the stop switch lock removed.

ENGINE STOP BUTTON

To stop the engine, push and hold the engine stop button or pull the lanyard out from the switch.

MANUAL STARTER HANDLE

To start the engine, first gently pull the handle out until resistanc e is felt. From that position, then pull the handle straight out quickly to crank the engine.

STEERING FRICTION ADJUSTER

A friction device provides adjust able resistance to the s teering mechanism, and can be set acc ording to operator preference. An adjust ing screw or bolt is located on the swiv el bracket.

GENERAL INFORMATION

TRIM ROD

The position of the trim rod determines the angle of the outboard motor in relation to the transom.

TILT LOCK MECHANISM

The tilt support lock keeps the outboard mot or in the tilted up position. If the out board engine needs to be tilted up out of the water or to get the propeller higher than the bottom of the boat, push down on the tiller handle while lifting up on carrying handle. Once the engine is all the way up, the tilt lock mechanism will engage and lock the engine in the up posit ion. To release the lock to lower the engine, pull up on the carrying handle to lift the engine up as far as it will go. While the engine is all the way up, lift up on the lock lever to disengage it while lowering the engine.

WARNING: Do not use the tilt support bar when trailering the boat. The outboard motor could shake loos e from the tilt support and fall. If the motor cannot be trailered in the normal running position, use an additional support device to secure it in the tilt position

TOP COVER LOCK LEVER

CARRYING HANDLE

A carrying handle is provided on the rear of the outboard motor. lt enables you to carry the outboard motor easily with one hand.

INSTALLATION

Incorrect engine height or obstructions to smooth water flow in front of the propeller can cause propeller cavita tion while the boat is cruising. Cavitat ion occurs when the engine speeds up momentarily and suddenly slows as the propeller engages the water. Severe engine damage may result if the motor is operated continuously while cavit ating. During water testing check the buoyancy of the boat, at rest, with its maximum load. Check that the static water level on the exhaust housing is low enough to prevent water entry in to the power head, when water rises due to waves when the outboard is not running.

MOUNTING THE OUTBOARD MOTOR

• Overpowering a boat could cause severe instability. Do not i nstall an outboard motor with more horsepower than the maximum rating on the capacit y plate of the boat. If the boat does not have a capacity plate, consult the boat manufacturer.

• This section is int ended as reference only. It is no

t possible to provide complete instructions for every possible boat and motor combinat ion. Proper mounting depends in part on experience and the specific boat and motor combination. Improper mount ing of the outboard motor could result in hazardous conditions, or poor handling, loss of control, or boat damage.

• Your dealer or ot her person experienced in proper out board m otor mountings should show you how to mount your motor. Mount the outboard mot or on the center line (keel line) of the boat, and ensure that the boat itself is well balanced. Otherwise the boat will be hard to steer. For boats without a keel or which are asymmetrical, consult your dealer.

MOUNTING HEIGHT

To run your boat a t best efficiency, the water resistance (drag ) of the boat and outboard motor must be made as little as possible. The mount ing height of the outboard motor greatly affect s the water resistance. If the mounting

height is too high, cavitation tends to occur, thus reducing the propulsion, and if the propeller tips cut the air, the engine speed will rise abnormally and cause the engine to over heat. If the mounting height is too low, the water resistance will increase and thereby reduce engine efficiency. Mount th e outboard motor so that the ant i-cavitation plate is between the bottom of the boat and a level 25mm (1in.) below it.

The optimum mounting height of the outboard motor is affected by the boat and motor combination and the desired use. Test runs at different heights can help determine the opt imum mounting height. Consult your boat manufacturer for further informat ion on determining the proper mounting height.

CLAMPING THE OUTBOARD MOTOR

1. Place the outboard motor on the transom so that it is positioned as close to the center as possible. Tighten the transom clamp screws evenly and securely. Occasionall y check the clamp screws for tightness during

operation of the outboard motor because they could become loose due to engine vibration.

WARNING: Loose clamp screws could allow the outboard motor to f all off or move on the transom. This could cause loss of cont rol and serious injury. Make sure the transom screws are tight ened securely. Occasionally check the screws for tightness during operation.

CENTER LINE (KEEL LINE)

ANTI-CAVITATION PLATE

RESTRAINT CABLE

2. If an engine restraint cable or chain attachment is equipped on your boat, the cable or chain should be used. Attach one end of the engine restraint cable attachment to the engine clamp and the other to a secure mounting point on the boat. Otherwise the engine could be completely lost i f it accidentally falls off the transom.

Page 10

OPERATION

PRE-OPERATION CHECKS

WARNING: If anything in the pre-operation check is not working properly, have it inspected and repaired before operating the outboard motor. Failure to do so could result in an accident.

CONTROLS

• Check throttle, shift, and steering for proper operation before starting the engine.

• The controls should work smoothly, without binding or unusual free play.

• Look for loose or damaged connections.

• Check operation of the starter and stop switches when the outboard motor is in the water.

• If the engine has not been used in some time, rev it in neutral to be sure it returns to idle before putting it

in gear.

ENGINE

• Check the engine and engine mounting.

• Look for loose or damaged fasteners.

• Check the propeller for damage.

CHECKING THE ENGINE OIL LEVEL

1. Put the outboard motor in an upright position (not tilted).

2. Check the oil level using the sight glass. The oil level should cover the met al plate visible just below the sight glass lens, but not so high as to touch the inside o f the glass.

Recommended engine oil: 4-stroke motor oil with a combination of the following SAE and API oil classifications

Engine oil type SAE: 10W-30

Engine oil grade API:

SE,S F, SG, SH, SJ, SL

Engine oil quantity:

0.37USqt (0.35L)

WARNING: ALL ENGINES ARE SHIPPED FROM THE FACTORY WITHOUT ENGINE OIL. ADD OIL BEFORE STARTING ENGINE.

FUEL

• Check to be sure you have plenty of fuel for your trip.

• Make sure there are no fuel leaks or propane fumes.

FUELING INSTRUCTIONS

WARNING: PROPANE AND ITS VAPORS ARE HIGHLY FLAMMABLE AND EXPLOSIVE!

• Stop engine before refueling.

• Do not smoke when refueling, and keep away from sparks, flames, or other sources of ignition.

• Refuel in a well-ventilated area.

• Refuel portable fuel tanks off the boat.

USE THE CORRECT PROPANE CANISTER

Always use propane canisters or “bottles” that are the correct size. The 17 ounce or 16.4 ounce / 465g canisters that are approximately 3-7/8 inches (9.5 cm) in diameter are the correct canisters.

NOTE: Do not use smaller diameter canisters as they will not latch securely to the unit and vibration may

cause damage to the unit and potentially result in a dangerous leak.

OPERATION

INSTALLING THE PROPANE CANISTER

1. Make sure the engine is o ff.

2. If the propane canister to be installed has a prot ective plastic cap ov er the threaded end, remove it. Make sure the canister clamp is in the unlatched position. If the rubber tank plug is in place, remove it. Save the plug for future use.

3. Pull the propane connector out from the bottle bracket through the canister clamp.

4. Insert the propane connector ont o the threaded end of the canister and s crew it clockwise onto threads. Screw it until snug. Do not over tight en.

NOTE: It may be normal to hear or smell a slight momentary leak of propane as the connector is being screwed in. Make sure that the connector is installed tight enough that any leakage stops. Hand tight is sufficient.

5. Insert the connected propane canister through the canister clamp and against the bottle bracket unt il it stops against it.

6. Latch the canister clamp closed.

REMOVING THE PROPANE CANISTER

1. Make sure the engine is o ff.

2. Unlatch the canister clamp

, pull the canister out, and remove the propane connector by turning it

counterclockwise.

3. Remove the empty canister.

4. Dispose of empty propane canisters in accordance to Federal, Sta te and Local regulat ions.

CONNECTING REMOTE PROPANE TANK

1. Make sure the engine is o ff and the propane tank is closed.

2. Connect the remote hose to the remote propane tank. Use only a high pressure propane hose. Do not use a hose with a regulator attached.

3. Unscrew the brass connector plug from the remote propane connector on the engine. Connect the remote hose to the remote propane connector.

4. If the engine is intended to be operated solely on the larger remote tank, insert the brass connector plug into the rear propane connector for the small bottle and install the provided rubber tank plug, and clamp it into place.

NOTE: When a new hose from a remote tank is being used, it may take a few seconds for the propane to flow to reach the engine. The engine may start and then die, or not start immediately. A few extra pulls of the starter are usually sufficient for the flow to reach the engine.

OPERATION

2. Attach the stop switch lanyard to a secure place on your clothing, or your arm or leg. Then install the lock plate on the ot her end of the lanyard into the engine stop switch.

• Do not attach the lanyard to clothing that could tear loose. Do not route the lanyard where i t could become entangled, preventing it from functioning.

• Avoid accidentally pulling the lanyard during normal operation . Loss of engine power means the loss o f most steering control. Also, without engine power, the boat could slow rapidly. This could cause people and objects in the boat to be thrown forward.

If the engine is cold, set the position about 1/8 to 1/4 of

a turn faster than the “start ” or Idle position.

4. Pull the manual start er handle slowly until you feel resistance. Then give a strong pull straight out to start the engine. Repeat if necess ary.

5. After the engine start s, slowly return the manual st arter h andle to the original position before releasing it .

6. Slowly return the throttle grip to the fully closed position.

NOTE: If the engine fails to st art after 4 or 5 tries, open the throttle a small amount (between 1/8 -1/ 4 throttle) and try again. Also if the engine is warm and fails to start, open the throttle a small amount and try to start the engine again. If the weather is below 45 degrees F, open the throttle to 1/4 - 1/2 to start cold.

WARMING UP ENGINE

1. Warm up the engine by operat ing at 1/2 throttle or less for the first 4 minutes. Failure to do so will cause the engine to stall in cold weather, and will shorten engine life.

2. Check for a steady flow of water from the cooling water pilot hole.

NOTE: A continuous flow of water from the cooling water pilot hole shows that the water pump is pumping water through the cooling passages. If water is not flowing out of the hole at all times while the engine is running, over heating and serious damage could

occur. Stop the engine and check whet her the cooling water inlet on the lower case or the coo ling water pilot hole is blocked. Consult your dealer if the problem cannot be locat ed and corrected.

SHIFTING

WARNING: Before shifting, make sure no swimmers are in the water near your boat.

1. Place the throttle in the slowest posit ion.

2. Move the gear shift lever quickly into gear from neutral to forward .

STOPPING ENGINE

1. Push and hold the engine stop button until the engine completely st ops.

2. After the engine has st opped disconnect the propane canister.

ADJUSTING BOAT TRIM

WARNING: Stop the engine before adjusting the trim angle. Use care to avoid being pinched when removing the trim bolt. Use caution when trying a trim position for the first time. Increase speed gradually and watch for any signs of inst ability or control problems. Improper trim angle can cause loss of control.

• Reposition the trim bolt inside the desired hole.

• To raise the bow (”t rim-out”), move the trim bolt away from the transom.

• To lower the bow (”t rim-in”), move the trim bolt closer to the transom.

• Test the boat with the trim set to different angles to find the

position that works best for your boat and

operating conditions.

NOTE: The outboard motor trim angle can be changed approximatel y 4 degrees by shifting the trim bolt one hole.

When the boat is on plane, a bow-up attitude results in less drag, greater stability and efficiency. This is generally when the keel line of the boat is up about 3 to 5 degrees. With the bow up, the bow of the boat may have a greater tendency to s teer to one side or the o ther. Compensate for this as you steer. The trim tab can also be adjust ed to help to help offset this effect. When the bow is down, it is easier to accelerate from a standing s tart onto plane.

BOW UP

Too much trim-out puts the bow of the boat too high in the wate r. Performance and economy are decreased because the hull of the boat is pushing the water and there is more drag. Excessive trim-out can also cause the

propeller to ventilate , which reduces performance further, and the boat may “porpoise” (hop in the water)

which could throw the operator and passengers overboard.

TRIM BOLT

• Tilt the engine up slightly.

TILTING UP AND DOWN

If the engine will be st opped for some time and the boat is moored in shallows, the outboard motor should be tilted up to prote ct the propeller and casing from damage from collision wit h obstructions, and also to reduce salt corrosion.

WARNING: Befor e tilting the outboard motor, follow the procedur e under “Stopping Engine” in thi s section. Never tilt the outboard motor while the engine is runnin g. Severe damage fro m overheating can result. Do not ti lt the engine by pu shing the tiller handl e only becau se this could brea k the handle.

WARNING: Be sure all people are clear of the outboard motor when tilting up and down, also be careful not to pinch any body part s between the drive unit and engine bracket.

PROCEDURE FOR TILTING UP

1. Place the gear shifter lever in neut ral and face the outboard motor forward.

2. Tighten the steering friction adjuster by turning it clockwise to prevent the motor from turning freely.

3. Hold the carrying handle and tilt the engine up fully until the tilt support lever automatically lock s.

PROCEDURE FOR TILTING DOWN

1. Slightly tilt the outboard motor up.

2. Slowly tilt the outboard motor down while pulling the tilt support lever up.

3. Loosen the steering friction adjuster by turning it counterclockwise, and adjust the s teering friction according to operator pref erence.

Use the carrying handle to help lift the engine. Keep the power unit higher than the propeller at all times otherwise water could run into the c ylinder and cause damage. The outboard motor cannot b e tilted when in reverse position.

BOW DOWN

Too much trim-in causes the boat to “plow” through the water, d ecreasing fuel economy and making it hard to increase speed. Operating with excessive trim-in at higher speeds also makes the boat unstable. Resistance at the bow is greatly increased, heightening the danger of “bow steering” and making operation difficult and dangerous.

NOTE: Depending on the type of boat, the out board motor trim angle may have little effect on the trim of the boat when operating.

TRANSPORTING AND STORING THE OUTBOARD MOTOR

WARNING: Leaking fuel is a fire hazard. When transporting or storing the outboard motor, disconnect the propane connector to prevent the possibility of fuel from leaking. Use care when transporting the fuel tank whether in boat or car.

Never get under the lower unit while i t is tilted, even if a motor support bar is used. Severe injury could oc cur if the outboard motor accidentally falls.

Do not use the tilt support lever when trailering the boat. The out board motor could shake loose from the tilt support and fall. If the motor can not be trailered in the normal running position, use an addit ional support device to secure it in the tilt position.

The outboard motor should be trailered and stored in the normal running position. If there is insufficient road clearance in this position, then trailer the outboard motor in the tilt position using a motor support device such as a transom saver bar.

When transporting or st oring the outboard motor while removed from a boat, keep the outboard motor in the attitudes shown.

MAINTENANCE

STORING THE OUTBOARD MOTOR

NOTE: Place a towel or something similar under the outboard motor to protect it from damage.

When storing your outboard motor for prolonged periods of time (2 months or longer), several important procedures must be performed to prevent excessive damage.

NOTE: Cooling system flushing is essent ial to prevent the cooling system from clogging up with salt sand, or dirt. In addition, fogging / lubricating of the engine is mandatory to prevent excessive engine damage due to rust. Perform the flushing and fogging at the same time.

• To prevent problems which can be caused by oil entering the cylinder from the sump, keep the outboard motor in the attit ude shown when transporting and st oring it. If storing or transporting the outboard motor on its side (not upright), put it on a cushion after draining the engine oil.

• Do not place the outboard motor on its side before the cooling water has drained from it completely, otherwise water may ent er the cylinder through the exhaust port and cause engine trouble.

• Store the outboard motor in a dry, well ventilated place, not in direct sunlight.

PROCEDURE FOR FLUSHING AFTER SEA WATER USE

If the engine has been operated in saltwater, it should always be flushed with fresh water after each use before being stored. Do

not

run

the

engine

without

supplying

the engine will be damaged from overheating. Be fore starting the engine, be sur e to supply

water to the cooling water passages.

1. Wash the out board motor body using fresh water.

2. Remove the engine top cover.

3. Install the outboard mot or on a test tank, or submerge the drive in water in some way, as long as the outboard is safely and securely mounted to a solid object.

4. Fill the tank with fresh wat er to above the level of the a nti-cavitation plate . If the freshwater level is below the level of the anti-cavit ation plate, or i f the water supply is insufficient, engine seizure may

occur.

5. Run the engine at a fa st idle for a few minutes in neut ral position.

WARNING: Never engage forward gear if engine is running when not attached to a boat. An exposed, spinning propeller is dangerous. Even in a tank, the engine can suddenly move when shifted into gear causing the tank or motor to shift and expose the propeller which could result in serious injury.

NOTE: Do not touch or remove elect rical parts when st arting or during operation. Keep hands, hair, and clothes away from the flywheel and ot her rotating parts while the engine is running.

ings.

CLEANING THE OUTBOARD MOTOR AFTER USE

1. After use wash the exterior of the outboard motor wit h fresh water.

2. Flush the cooling syst em with fresh wat er.

CHECKING PAINTED SURFACE OF MOTOR

1. Check the motor for scratches, nicks, or flaking paint. Areas with damaged paint are more likely to corrode. If necessary, clean and paint the areas.

NOTE: Be sure to turn o ff the engine when you perform maint enance unless otherwise specified. If you or the owner are not familiar with machine servicing, this work should be done by your LEHR dealer or other qualified mechanic.

REPLACEMENT PARTS

If replacement parts are necessary, use only genuine LEHR parts or parts of the same type and of equivalent strength and materials. Any part of inferior qualit y may malfunction, and the resulting loss of control could endanger the operator and passengers. LEHR genuine parts and accessories are available from your LEHR dealer, or directly from LEHR.

MAINTENANCE CHART

Frequency of maintenance operat ions may be adjusted ac cording to the operating conditions, but the following table gives general guidelines. Refer to the sections in this chapter for explanations o f each owner-specificaction. When operating in salt wat er or dirty water, the engine should be flushed with clean water after each use.

GREASING

NOTE: Use only water resist ant grease.

Grease in these areas:

Spark plug gap:

0.020-0.024in (0.5-0. 6mm)

Spark plug torque: l8.4ft-lb (25.0Nm)

SPARK PLUG

WARNING: When removing or installing a spark plug, be careful not to damage the insulator. A damaged insulator could allow ext ernal sparks, which could lead to explosion or fire.

The spark plug is an important engine part and is easy to inspect. The condition of the spark plug c an indicate the condition o f the engine. Normally, the spark plug in a propane engine will stay very clean. Oily or dark color ceramic could indicate a malfunction. Do not attempt to diagnose any problems yourself. Instead, take the outboard mot or to a LEHR dealer. You should periodically remove and inspect the spark plug because the electric arcing will cause the spark plug to s lowly erode and the gap will increase. If electrode erosion becomes excessive, or i f carbon and other deposits are excessive, you should replace the spark plug with another of the correct type.

Before fitting the spark plug, measure the electrode gap with a wire thickness gauge. Adjust the gap to specific ation if necessary.

When

fitting the plug, always clean the gasket surface and use a new gasket. Wipe o ff any dirt from the

threads and screw in the spark plug to the correct torque.

NOTE: If a torque-wrench is not available when you are fitting a spark plug, a good estimate of the correc t torque is 1/4 to 1/2 a turn past finger tight. Have the spark plug adjusted to the correct torque as soon as possible with a torque wrench.

INSPECTION CHECKPOINTS

Periodically check the fuel system for leaks. With the propane tank attached, and the engine cover removed, inspect the following fuel system parts for leakage. Leaks can be identified by smell of propane or carefully listening for a hissing sound of escaping gas. Suspected leaks can be verified by applying soapy water solution on the area and observing bubbles forming.

ADUSTING IDLING SPEED

WARNING: Do not touch or remove electrical parts when s tarting or during operation. Keep hands, hair, and clothes away from the flywheel and o ther rotating parts while the engine is running.

CAUTION: This procedure must be performed while the outboard m otor is in the water. A flushing attachment or test tank can be used.

NOTE: A diagnostic tachometer should be used for this procedure. Results may vary depending on whether testing is conducted wit h the flushing attachment, in a test tank, or with the outboard motor in the water.

1. Start the engine and allow i t to warm up fully in neutral until it is running smoothly.

NOTE: Correct idling speed inspection is only possible if the engine is fully warmed up. If not warmed up fully, the idle speed will measure higher than normal. If you have difficulty verifying the idle speed, or the idle speed requires adjustment, consult a LE HR dealer or other qualified

mechanic.

2. Verify whether the idle speed is set to specificat ion (2000 150 RPM). Adjust the speed by turning the idle speed screw with a phillips head screwdriver. An access hole is provided in the rear lower cover

which allows a long screwdriver to be inserted into the idle speed screw at the proper angle. Remove the

rubber plug to use this hole.

CHANGING ENGINE OIL

WARNING: Avoid draining the engine oil immediately after stopp ing the engine. The oil is hot and should be handled with care to avoid burns.

• Be sure the outboard motor is securely fastened to the transom or a stable stand.

• Do not overfill the oil, and be sure the outboard motor is upright (not tilted) when checking and changing

the engine oil.

• If the oil level is above the upper level mark, drain until the level meets the specified capacity. Overfilling the oil could cause leakage or damage.

• Change the engine oil a fter the first 10 hours of operation, and every 100 hours or at 6 month intervals thereafter. Otherwise the engine will wear quickly.

NOTE: Change the engine oil when the oil is still warm.

1. Put the ou

tboard motor in an upright position (not tilted).

2. Prepare a suitable container that holds a larger amount tha n the engine oil capacity . Loosen and remove the oil drain plug while holding the container under the drain hole. The oil drain plug is located on the

PROPELLER SELECTION

Your LEHR outboard engine is supplied with a propeller that matches the needs of a boat most suited to an engine of its size. If you feel you are not getting optimal performance from the engine on your boat, a different pitch propeller could help. The performance of your outboard motor will be affected if you choose a different propeller, as an incorrect choice could adversely affect performance and could also seriously damage the motor. Engine speed depends on the propeller size and boat load. If engine speed is too high or too low for good engine performance, this will have an adverse effect on the engine. For a greater operating load, a smaller-pitch propeller is more suitable as it enables the correct engine speed to be maintained. Conversely, a larger-pitch propeller is more suitable for a smaller operation load.

1. Propeller diameter in inches.

2. Propeller pitch in inches.

3. Type of propeller (propeller mark).

NOTE: Select a propeller which will allow the engine to reach the middle or upper half of the operation range at full throttle with the maximum boat load. In operation conditions such as light boat loads, do not allow the engine RPM to rise above the maximum recommended range, reduce the throttle setting to maintain the engine in the proper operation range.

• Always use new gaskets .

• Do not reuse the removed gasket s.

4. Remove the oil Ievel plug to allow the oil to drain completely. Inspect the used oil a fter it has been drained. If the oil is milky, water is getting into the gear case which can cause gear and bearing damage. Consult your LEHR dealer for repair of the lower unit seals.

5. With the out board motor in a vert ical position and using a flexible or pressurized filling device, inject the gear oil into the gear oil drain screw hole.

6. When the oil begins to flow out o f the oil level plug hole, insert and tighten the oil level plug.

7. Insert and tighten the gear oil drain screw.

ANODE

INSPECTING AND REPLACING ANODE

LEHR outboard mot ors are protected from corrosion by a sacrif icial anode. Inspect the external anode periodically. Remove scales from the surfaces o f the anode. Do not paint the anode, as this would render it ineffective.

COATING THE BOAT BOTTOM

A clean hull improves boat performance. The boat bottom should be kept as clean of marine growth as possible. If necessary, the boat bottom can be coat ed with an anti-f ouling paint approved for your area to inhibit marine growth . Do not use anti-f ouling paint which includes copper or graphit e. These paints can cause more rapid engine corrosion.
