UNDERSTANDING PROPANE

SAFETY WARNINGS FOR PROPANE UNITS

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.

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.

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.

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

LOCK LEVER

TILT LOCK LEVER

TRIM ROD

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

TILT LOCK MECHANISM

The tilt support lock keeps the outboard mot or in the tilted up posit ion. If the outboard 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 loose 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

To remove the engine top cover, remove the 1 lb. propane tank or rubber plug. Pull the lock levers upwards from the bottom and unhook from the top cover. Then lift the cover. When installing the cover, check to be sure it fits properly on the rubber seal. Then lock the cover by moving the levers downward.

CARRYING HANDLE

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

CARRYING HANDLE

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. Cavit ation oc curs 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 test ing check the buoyancy of the boat, at rest, with i ts maximum load. Check that the static water level on the exhaust housing is low enough to prevent wat er 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 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 mot or 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.

t possible to provide complet e instructions for every

ANTI-CAVITATION PLATE

CENTER LINE (KEEL LINE)

MOUNTING HEIGHT

To run your boat a t best efficiency, the water resist ance (drag) of the boat and outboard motor must be made as little as possible. The mount ing height of the outboar d motor greatly affects the wat er resistance. If the mounting 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 the outboard motor so that the ant i-cavitation plat e is between the bottom of the boat and a level 25mm (1in.) below it.

The optimum mounting height of the outboard mot or is affected b y the boat and motor combination and the desired use. Test runs at different heights can help determine the optimum 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 fall off or move on the transom. This could cause loss of cont rol and serious injury. Make sure the transom screws are tightened securely. Occasionally check the screws for tightness during operat ion.

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 o ther to a secure mounting point on the boat. Otherwise the engine could be complet ely lost if it accidentally falls off the transom.

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 metal plate visible just below the sight glass lens, but not so high as to touch the inside o f the glass.

OIL LEVEL SIGHT 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

STARTING ENGINE

1. Place the gear shift lever in neutral. Always start the engine in neutral to avoid accidentally moving the boat.

WARNING: Keep hands, hair, and clothing away from rotating parts while the engine is running. Do not touch or remove electrical parts when starting or during operation.

2. Attach the stop switch lanyard to a sec ure place on your clot hing, or your arm or leg. Then install the lock plate on the ot her end of the lanyard into the engine s top switch.

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

• Avoid accidentally pulling the lanyard during normal operatio n. Loss of engine power means the loss of 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.

SHIFTING

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

1. Place the throttle in the slowest posit ion.

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

STOPPING ENGINE

1. Push and hold the engine stop button until the engine completely stops.

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 a void 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 cont rol problems. Improper trim angle can cause loss of control.

• Tilt the engine up slightly.

• 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

operating conditions.

position that works best for your boat and

TRIM BOLT

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

When the boat is on plane, a bow-up attitude results in less drag, greater stabilit y 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 other. Compensat e 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 accelerat e from a standing s tart onto plane.

BOW UP

Too much trim-out puts the bow of the boat too high in the water. 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

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

the which could throw the operator and passengers overboard.

Page 14

OPERATION

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 a t higher speeds also makes the boat unstable. Resistance at the bow is greatly increased, heightening the dan ger 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 o f the boat when operating.

TILTING UP AND DOWN

If the engine will be st opped for some time and the boat is moored in shallows, the outboard mot or should be tilted up to prote ct the propeller and casing from damage from collision with obstruct ions, and also to reduce salt corrosion.

WARNING: Befor e tilting the o utboard motor, follow the proc edure under “Stoppin g Engine” in th is section. Never tilt the outboard motor while the engine is running. Severe damage from o verheating can result. Do not tilt th e engine by pus hing the tiller handle only beca use this coul d break the handle.

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 cylinder and caus e damage. The outboard motor cannot be tilted when in reverse position.

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

PROCEDURE FOR TILTING UP

1. Place the gear shifter lever in neut ral and face the outboard mot or 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 automat ically locks.

MAINTENANCE

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 occur 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 additional support

device to secure it in the tilt position.

The outboard motor should be trailered and st ored in the normal running posit ion. If there is insufficient road clearance in this position, then trailer the outboard motor in the tilt position using a motor support devic e 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 syst em from clogging up with salt sand, or dirt. In addition, fogging / lubricating of the engine is mandat ory 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 ent ering the cylinder from the sump, keep the outboard motor in the attit ude shown when transporting and storing it. If storing or transporting the outboard mot or on its side (not upright), put it on a cushion after draining the engine oil.

• Do not place the outboard motor on it s 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 vent ilated 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 damaged

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 o f the anti-cavita tion plate. If the freshwater level is below the level of the anti-cavit ation plate , or if the wat er supply is insufficient, engine seizure may occur.

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

SPARK PLUG

WARNING: When removing or installing a spark plug, be caref ul not to damage the insulat or. 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 can 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 L EHR dealer. You should periodically remov e 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 off any dirt from the

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

Standard spark plug: BR6H8

Spark plug gap:

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

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

NOTE: If a torque-wrench is not available when you are fitting a spark plug, a good estimate of the correct 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.

NOTE: Inspect the following for any source of a fuel leak.

• Fuel system parts leakage

• Fuel line joint leakage

• Fuel line cracks or other damage

• Fuel connector leakage

ADUSTING IDLING SPEED

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

CAUTION: This procedure must be performed while the out board motor is in the water. A flushing attachment or test tank can be used.

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

1. Start the engine and allow i t to warm up fully in neutral u ntil 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 norm al. If you have difficult y 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 specification (200 0 150 R PM). 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.

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.

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.
