UNDERSTANDING PROPANE

SAFETY WARNINGS FOR PROPANE UNITS

NOTE: Use propane only in tanks speciﬁcally 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 identiﬁed, turn o the engine. If the leak persists, remove the propane tank. Never attempt to operate a unit that has a suspected leak. Always remove the propane tank from any unit that has a suspected leak.

Leakage of liquid propane can cause serious frostbite damage to skin. If you see liquid propane leaking, do not attempt to touch the area. Turn o the valve on the tank and let the leak dissipate.

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 OF PROPANE TANKS

1. Keep out of reach of children.

2. Never expose to heat, sparks, or ﬂame.

3. Never store in direct sunlight.

4. Never store at temperatures above 120

° F (49° C).

5. Never store in living spaces.

6. Always use tank until it is completely empty.

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

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

9. Never put in ﬁre or incinerator. Do not puncture.

NOTE: FIRE/EXPLOSION HAZARD

Propane tanks contain enough gas to cause serious ﬁre, explosion, and burns. To reduce chance of leak, ﬁre, or explosion, take the following precautions:

BEFORE USE

1. Check tank and hose seals. Never use with damaged or missing seals. Clean tank if dirt or rust particles are in valve area.

2. Attach tanks outdoors away from pilot lights, ﬂames, sparks or other ignition sources. These sources can ignite leaking gas.

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

4. 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.

5. Read and follow operation instructions.

DURING USE

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

AFTER USE

1. Turn engine o and let cool.

2. Detach tank when not in use.

3. Detach outdoors away from pilot lights, ﬂames, sparks, or other ignition sources, they can ignite leaking gas.

4. Replace valve and connector caps to keep them clean.

IN CASE OF FIRE

1. Leave area quickly and call for help.

2. Let the tank burn out.

WARNING:

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

INSTALLATION

Incorrect engine height or obstructions to smooth water flow in front of the propeller can cause propeller cavitation while the boat is cruising. Cavitation 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 cavitating. 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 eno 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 install an outboard motor with more horsepower than the maximum rating on the capacity plate of the boat. If the boat does not have a capacity plate,

consult the boat manufacturer.

be 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 optimum mounting height. Consult your boat manufacturer for further information 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. Occasionally 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 control and seri Occasionally check the screws for tightness during operation.

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 if it accidentally falls

OPERATION

When t he boat is on plane, a bow-up attitude results in less drag, greater stability and efficiency. This is generally when t he k eel line of the boat is up about 3 t o 5 degrees. With t he bow up, the bow of the boat may have a greater t endency t o steer to one side or t he other. Compensate f or t his as you steer. The t rim t ab can also be adjusted to help to help offset this effect. When the bow is down, it is easier t o accelerate f rom a standing start onto plane.

WATER LINE

BOW UP

Too much trim-out puts t he bow of the boat too high in the water. Performance and economy are decreased because the hull of the boat is pushing t he water and t here is more drag. Excessive trim-out can also c ause the propeller to ventilate, which reduces performance further, and t he boat may “porpoise” (hop in the water) which could t hrow

BOW DOWN

Too much trim-in causes the boat to “plow” through t he water, decreasing f uel economy and making it hard to increase speed. Operating with excessive t rim-in at higher s peeds also makes t he 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 t ype of boat, the outboard motor t rim angle may have little effect on t he t rim of the boat when operating.

TILTING UP AND DOWN

If the engine will be stopped f or some time and the boat is moored in shallows, the outboard motor should be tilted up t o protect the propeller and casing f rom damage f rom collision with obstructions, and also to reduce salt corrosion.

WARNING: Before tilting the outboard motor, follow the procedure under “Stopping Engine” in this section. Never result. Do not tilt the engine by pushing the tiller handle alone because this could break the handle. Hold f rom t he rear of the top cover t o help t ilt the engine up and down. 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 be tilted while in reverse.

SPARK PLUGS

WARNING: When removing or installing a spark plug, be careful not to damage the insulator. A damaged insulator could allow external 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 of the engine. Normally, the spark plug in a propane engine will stay very clean. Oily or dark c olor ceramic could indicate a malfunction. Do not attempt to diagnose any problems yourself. Instead, take the outboard motor to a LEHR dealer. You should periodically remove and inspect the spark plug because the electric arcing will cause the spark plug to slowly erode and t he gap will increase. If electrode erosion becomes excessive, or if carbon and other deposits are excessive, you should replace the spark plug with an

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

specification 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 plu
