Use caution when connecting the battery
cables. Improperly connecting the battery
cables or using the wrong battery type can
damage electrical components. These dam-
ages are not covered by your warranty.
CHECK ENGINE LIGHT (EFI ENGINES ONLY)
Some boats are equipped with a Check Engine light
which alerts you when the ECM (engine control module)
detects a possible engine problem. If the light goes on,
return to dealer for service. When a problem is detected,
EFI engines may enter a Power Reduction mode. Power
reduction limits the engine speed to a “safe maneuver-
ing” speed of about 1600 RPM. This mode is intended to
allow the driver to get out of harms way and to reach
safe harbor for engine service.
Figure 4.5 – Typical Check Engine Light
The Check Engine light may activate if any of the follow-
ing conditions are noted:
• Low Oil Pressure
• High Coolant Temperature
• High Transmission Oil Temperature
Any of these conditions will also put the engine into
Power Reduction mode. If the Check
Engine light should go on, or if the engine enters the
Power Reduction mode, you should have your dealer
check the engine as soon as possible.
Schedule engine service at once when this
light is illuminated. Failure to have your
engine serviced when a check engine light
signal is given, may cause damage to your
engine or your emissions system.
The ECM also provides for a tapered engine RPM
reduction if engine coolant temperature approaches the
high operating limit. If the coolant temperature exceeds
176° F (80° C), the engine RPM is gradually reduced
until a safe temperature is reached. If the engine RPM
should decrease due to high coolant temperature, stop
the engine and inspect the raw water intake, sea cock
and sea strainer (if equipped) and hoses for blockage or
problems.
