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 other 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 it could become

entangled, preventing it from functioning.

• Avoid accidentally pulling the lanyard during normal operation. 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.

3. Place the throttle

grip

in the "START" position

.

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 starter handle slowly until you feel resistance. Then give a strong pull straight out to

start the engine. Repeat if necessary.

5. After the engine starts, slowly return the manual starter handle to the original position before releasing it.

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

NOTE: If the engine fails to start 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 operating 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 whether

the cooling water inlet on the lower case or the cooling water pilot hole is blocked. Consult your

dealer if the problem cannot be located and corrected.

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.
