2007 YAMAHA FX HO CRUISER fuel type

Features and functions
31
There are 5 positions: 2 bow-down positions
(a) and (b), neutral “N”, and 2 bow-up posi-
tions (c) and (d).
To change the trim angle:
(1) Reduce engine speed to 4000 r/min or
less.
(2) Squeeze the QSTS selector lock lever,
and then turn the QSTS selector to the
desired position.
(3) Release the lock lever to lock the QSTS
selector.
CAUTION:
ECJ00010
Do not turn the QSTS selector while oper-
ating the watercraft at full throttle, other-
wise damage could occur to the QSTS.
The neutral “N” position will provide good per-
formance for most operating conditions.To enhance particular types of performance,
select bow down or bow up.
EJU31330Bow down
Turn the QSTS selector to (a) or (b) and the
bow will go down while the watercraft is on
plane.
Bow down puts more of the bow in the water.
This gives the watercraft more “hook”, which
enhances turning performance. This position
will also help the watercraft get up on plane
more quickly.
At higher speeds, however, the watercraft will
have a greater tendency to “bow steer” and
follow waves and wakes in the water. Fuel
economy and maximum speed are also re-
duced.
EJU31340Bow up
Turn the QSTS selector to (c) or (d) and the
bow will go up while the watercraft is on plane.
Bow up puts less of the bow in the water.
There is less water resistance, so straight-

Fuel and oil
This watercraft is equipped with a 4-stroke en-
gine. Conventional 2-stroke engine oil cannot
be used.
The engine utilizes an electronic fuel injection
system to deliver the optimal air-fuel ratio re-
quired by the engine. By ensuring the optimal
combustion conditions, this system is able to
increase startability and improve fuel econo-
my.
EJU36330Gasoline
WARNING
EWJ00280
GASOLINE AND ITS VAPORS ARE HIGH-
LY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and keep
away from sparks, flames, and other
sources of ignition.

Stop the engine before refueling.

Refuel in a well-ventilated area with the
watercraft in a horizontal position.

Do not stand or sit on the watercraft
while refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level reaches approxi-
mately 50 mm (2 in) from the top of the
fuel tank. Fuel expands as it warms up
and could overflow if the fuel tank has
been overfilled. If temporarily leaving
the watercraft with a full fuel tank, do not
leave it in direct sunlight. Leave it in a
well-ventilated area with the watercraft
in a horizontal position.

Tighten the fuel tank filler cap securely
after refueling.

If you should swallow some gasoline, in-
hale a lot of gasoline vapor, or get gaso-
line in your eyes, get immediate medical
attention.

If any gasoline spills on your skin or
clothing, immediately wash the affected
area with soap and water and change
your clothes.
CAUTION:
ECJ00320

Do not use leaded gasoline. Leaded gas-
oline can seriously damage the catalytic
converter.

Use only fresh gasoline that has been
stored in clean containers.
EJU31860Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and the
fuel meets the minimum octane ratings.
Gasohol containing methanol is not recom-
mended by Yamaha because it can cause
fuel system damage and engine performance
problems.Recommended gasoline:
Regular unleaded gasoline with a mini-
mum octane rating of
86 (Pump octane number) = (R +
M)/2
90 (Research octane number)
