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
under the front of the rear seat.
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
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.
Remove the cap again and check
the oil level.
3) The oil level should be between the
minimum and maximum level
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.
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.
3-2
While many additives available may
reduce deposits, Yamaha recommends
the use of Ring Free Fuel Additive,
available from your Yamaha dealer.
Ring Free has repeatedly proven its
ability to clean combustion deposits
from inside the engine, notably in the
critical piston-ring-land area, and fuel
system components. Follow product
labeling for use instructions.
ENGINE OIL
Recommended oil: YAMALUBE 4-W. If
YAMALUBE 4-W is not available,
another 10W-30 4-cycle engine oil with
an API rating of SE, SF, SG, SH, or SJ.
GASOLINE
AND ENGINE OIL
FILLING
FILLING THE GASOLINE TANK
Open the fuel tank filler cap, and slow-
ly add fuel to the fuel tank. Be careful
not to spill fuel or overfill the tank.
Stop filling when the fuel just becomes
visible in the bottom of the filler tube.
Do not “top off” the tank, because
gasoline could spill out. Be sure to
tighten the cap securely.
Be careful when refueling. Avoid
getting water or other contaminants
in the fuel tank. Contaminated fuel
can cause poor running or engine
damage.
Fuel tank capacity: 50 US gal (189 lit)
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 lit-
tle oil, the engine can be damaged. If
there is too much oil, the air filter
can become saturated with oil, per-
manently damaging the filter and
reducing engine performance.
Follow the checking procedure
carefully.
NOTE:
•
Each engine has an oil-tank sys-
tem. It is normal for the oil level to
vary depending upon whether the
engine is cold or at operating tem-
perature.
• Adding 1 US qt. (0.95 l) of oil will
raise the oil level on the dipstick by
approximately 2.2 in. (5.6 mm).
