To check oil, be sure the boat is level,
either in the water or on the trailer.
Open the engine compartment by
pulling up on the two latches located

Cold Engine Check
1) Remove the oil tank filler cap 1,
wipe the dipstick with a clean rag,
and then screw the cap on securely.
Remove the cap again and check
the oil level.
2) If the level is at least at the minimum
level "L" mark 2 on the dipstick, but
less than the "F" mark 3, the engine
can be operated.
3) If oil must be added, add just
enough oil to raise the level to the "L"
mark. Adding more oil could result in
an overfilled engine once it warms
up.
4) Repeat for the other engine.
Warm Engine Check
1) Be sure the engine is warmed to
1
operating temperature.
NOTE: The engines are at the proper
operating temperature after they have
been run for 5 minutes or more at 7,000
rpm or above and then at a trolling
speed for 2~3 minutes. If the boat is on
the trailer, run the engine with the flush
attachment at an idle speed for 6 to 8
minutes, or at least 13 minutes if air
temperature is 59° F (15°C) or colder.
2) Remove the oil tank filler cap 1,
wipe the dipstick with a clean rag,
and then screw the cap on securely.
3
Remove the cap again and check
the oil level.
3) The oil level should be between the
minimum
marks. If the level is below the "L"
mark 2, then add only enough oil to
raise the level above the "L" mark but
never above the "F" mark 3.
4) Repeat for the other engine.
CAUTION:
If the level is above the "F" mark, the
engine is overfilled. Consult a
Yamaha dealer to have oil extracted
from the engine to avoid damage.
