Engine oil level check
Do not allow the oil tank to become com-
pletely empty. If the oil tank becomes
empty the oil injection pump must be bled
to ensure proper oil flow, otherwise
engine damage may occur. See “Oil pump
air bleeding” (4-18).
Make sure that debris or water does not
enter the oil filler hole.
1. Remove the oil tank filler cap.
2. Slowly add engine oil to the oil tank.
3. Stop filling when the oil level just reaches
the top of the oil tank.
4. Install the oil tank filler cap.
Trolling speed check
1. Place the watercraft in the water.
2. Start the engine and warm it up for 6 min-
utes or more at engine idle speed.
TIP:
Warm up the engine an additional 5 minutes
if the ambient temperature is 20 °C (68 °F) or
less.
3. Connect the special service tool 1 to the
spark plug wire.
4. Check the trolling speed.
Trolling speed adjustment
1. Turn the low speed screws 1 until they
are lightly seated, and then turn out the
low speed screws
1 to the specified
number of turns.
2. Start the engine.

2
in or out
until the specified speed is obtained.
Engine mount check
1. Check the engine mounts. Replace if

mount so that it can be installed in its origi-
nal place.

sure to check the coupling clearance.
