Watercraft glossary
Trolling speed
“Trolling” is the lowest maneuvering speed. You are applying little or no throttle. The water-
craft is down in the water, and there is no wake.
Sub-planing speed
“Sub-planing” is a medium speed. The bow of the watercraft is slightly up from the water sur-
face, but you are still traveling through the water. There is a wake.
Planing speed
“Planing” is a faster speed. The watercraft is more level and is skimming on top of the water.
There is a wake.
Bow
The front end of the watercraft.
Stern
The rear end of the watercraft.
Starboard
The right side of the watercraft when facing forward.
Port
The left side of the watercraft when facing forward.
Bilge water
Water that has collected in the engine compartment.
Yamaha Engine Management System (YEMS)
YEMS is an integrated, computerized management system that controls and adjusts ignition
timing, fuel injection, engine diagnostics, and the off-throttle steering (OTS) system.
Reverse with Intuitive Deceleration Electronics (RiDE)
RiDE is an electronic system that controls the reverse, neutral, and deceleration operations of
the watercraft.

WARNING
EWJ00283
Gasoline and gasoline vapors are ex-
tremely flammable. To avoid fires and
explosions and to reduce the risk of in-
jury when refueling, follow these in-
structions.
Gasoline is poisonous and can cause in-
jury or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline, inhale a
lot of gasoline vapor, or get some gaso-
line in your eyes, see your doctor imme-
diately. If gasoline spills on your skin,
wash with soap and water. If gasoline
spills on your clothing, change your
clothes.
NOTICE
ECJ00322
Do not use leaded gasoline. Leaded
gasoline can seriously damage the en-
gine.
Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause poor performance and engine
damage. Use only fresh gasoline that
has been stored in clean containers.
Gasohol
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.
E-85 is a fuel blend containing 85% ethanol
and therefore must not be used in this water-
craft. All ethanol blends containing more than
10% ethanol can cause fuel system damage
or engine performance problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage and engine performance
problems.
To fill the fuel tank:
(1) Before refueling, stop the engine. Do not
stand or sit on the watercraft. Never refu-
el while smoking, or while in the vicinity
of sparks, open flames, or other sources
of ignition.
(2) Place the watercraft in a well-ventilated
area and in a horizontal position.
(3) Remove the seats, and then check the
fuel level. (See page 43 for seat removal
and installation procedures.)
(4) Pull the hood latch up, and then lift up
the rear of the hood.
Recommended fuel:
Regular unleaded gasoline with a mi-
nimum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)
