2007 YAMAHA GP1300R fuel type

Features and functions
26
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-
ahead acceleration when on plane and top
speed are enhanced.
In some conditions, however, the watercraft
may tend to “porpoise” (hop in the water). If
the watercraft is porpoising, select neutral or
bow down.
EJU31350Handgrip
The handgrip provides a handhold for board-
ing the watercraft.
WARNING
EWJ00020
Do not use the handgrip to lift the water-
craft. The watercraft could fall, which
could result in severe injury.
EJU34870Bow eye
The bow eye is located at the bow of the wa-
tercraft.

The bow eye is used to attach a rope to the
watercraft when transporting, mooring, or
towing it in an emergency.
EJU36020Stern rope holes
The stern rope holes are located at the stern
of the watercraft.
The stern rope holes are used to attach a rope
to the watercraft when transporting or moor-
ing it.
EJU31370Yamaha Engine Management System
(YEMS)
This model is equipped with an integrated,
computerized management system that con-
trols and adjusts ignition timing, fuel injection,
engine diagnostics, and the off-throttle steer-
ing (OTS) system.
EJU31420Multifunction information center
This meter contains the following functions for
help and convenience in operating the water-
craft.
CAUTION:
ECJ00060

Do not run the engine over 4000 r/min
when checking the operation of the
meter on land without supplying water,
otherwise the engine could overheat
and the catalytic converter could be se-
riously damaged.

Use the specified resistor-type spark
plugs and caps, otherwise the meter
may function erratically.
NOTE:

When the engine is started, all displays light
up for a few seconds, the buzzer sounds
twice, and then the meter starts to operate
normally.

Fuel and oil
This engine uses Yamaha’s oil injection sys-
tem, which provides superior lubrication by
ensuring the proper fuel-to-oil ratio for all op-
erating conditions. No fuel premixing is nec-
essary, except during the engine break-in
period. Simply pour gasoline into the fuel tank
and oil into the oil tank.
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.
EJU31850Gasoline
WARNING
EWJ00440
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 just reaches the
bottom of the filler tube. Do not fill up the
filler tube because fuel expands as it
warms up and could overflow. If tempo-
rarily leaving the watercraft with a full
fuel tank, do not leave it in direct sun-
light. Leave it in a well-ventilated areawith the watercraft in a horizontal posi-
tion.

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)
