OVERHEAT WARNING SYSTEM
The engine has an overheat warning
device. If either engine starts to over-
heat, the engine speed of the affected
engine will be limited to 3000 rpm.
Each engine is equipped with cooling-
water pilot outlets on the starboard side
of the hull. Check that water comes out
of the outlet while the engine is run-
ning, particularly while applying throttle.
If you do not see any water at the out-
let, cooling water may not be circulating
in the engine.
NOTE: If water cooling passages on
the engines are dry, it will take about 20
seconds for water to reach the pilot out-
lets after starting.
If water is not circulating, something
may be clogging the jet intake grate.
Refer to the Jet Pump Clean-Out pro-
cedures on page 5-5 for further infor-
mation.
If the cause of overheating cannot
be found and corrected, take special
precautions to avoid major engine
damage while you return to shore.
SINGLE ENGINE OVERHEATING —
Shut off the overheating engine and
use the properly running engine to
return to shore. Operate at “no-
wake” speed to prevent water from
flooding the non-operating engine
through the cooling water intake.
BOTH ENGINES OVERHEATING —
If getting a tow from another vessel
is not possible, operate both
engines just slightly above idle
while you return to shore. If you can
be towed, refer to “Towing the Sport
Boat” on page 5-3.

CAUTION:
3. Fuel Level Gauge
The fuel level gauge shows the
amount of fuel in the fuel tank. The
ignition switch must be in the “ON”
position to activate the gauge.
Always consider the distance you are
traveling and the amount of fuel you
have available. Be sure you have
enough fuel to reach your next fuel
stop. A good tip to remember is to use
a third of your fuel to get out, a third to
get back, and keep a third in reserve.
Low Fuel Warning Indicator – If the fuel
tank is too low to continue normal oper-
ation much longer, this warning light
1
will come on. Refill the fuel tank as
soon as possible (see “Filling the Fuel
Tank,” page 3-3).
4. Compass
The compass shows your direction
of travel.
5. Warning Indicators
There are three warning indicators
in each tachometer to alert you
about certain conditions on your
Sport Boat. These warnings corre-
spond to the engine monitored by
the tachometer.
Check Engine – If a sensor mal-
function or a short circuit is detect-
ed, the warning indicator will come
on. If this occurs, reduce engine
speed and return to shore. Have a
Yamaha dealer check the engine
and circuits.
Engine Overheat – This model is
equipped with an engine overheat
warning system. See the following
section for an explanation.
Oil Pressure – If oil pressure does
not rise to specification, the oil pres-
sure warning indicator comes on. At
the same time, engine speed reduc-
tion control is activated, limiting
maximum speed to 3000 rpm. If this
occurs, reduce engine speed and
return to shore. Have a Yamaha
dealer check the engine oil pres-
sure.
