PERATION

also helping to keep fuel injectors and
other fuel system components clean for
proper performance and longer engine
life.
ENGINE OIL

Yamalube 4W
Recommended engine oil type:
SAE 10W-30, 10W-40, 20W-40,
20W-50
Recommended engine oil grade:
API SE, SF, SG, SH, SJ, SL
ENGINE OIL LEVEL
Check the oil level in both engines
before each use. Check the oil on each
engine when cold to be sure there is
enough oil to run the engine
Be sure the engine has enough oil
but do not overfill. If there is too little
oil, the engine can be damaged. If
there is too much oil, the air filter can
become saturated with oil, perma-
nently damaging the filter and reduc-
ing engine performance. Follow the
checking procedure carefully.
TIP:
• Each engine has an oil-tank system.
It is normal for the oil level to vary
depending upon whether the engine
is cold or at operating temperature.
• Adding 1 US qt. (0.95 lit) of oil will
raise the oil level on the dipstick by
approximately 2.2 in. (56 mm).
To check oil, be sure the boat is level,
either in the water or on the trailer.
Open the engine compartment by pull-
ing up on the two latches located under
the front of the rear seat.
Cold Engine Check
1) Remove the oil tank filler cap
wipe the dipstick with a clean rag,
and then screw the cap on securely.
Remove the cap again and check
the oil level.
