“SERVICE REQUIRED” OR “CHECK ENGINE” INDICATOR
Some boats are equipped with a digital dash which displays the
words “SERVICE REQUIRED” and/or “CHECK ENGINE,” and
some boats are equipped with a Check Engine light. This alerts you
when the ECM (Engine Control Module) detects a possible engine
problem. If the indicator goes on, return to dealer for service.
In addition to the check engine light, some boat manufacturers
have digital displays on the dashboard of the boat that display
trouble/fault codes generated by the OBD-M system. These
displays may not always be accurate and the information displayed
might not indicate the actual problem. We recommend that you
contact your dealer when you have a trouble/fault code displayed
to have the issue verified with a Diagnostic Scan Tool.
If any of the following conditions is noted:
x Low Oil Pressure
x High Coolant Temperature
x High Transmission Oil Temperature
x Excessive Catalytic Converter Temperature
x Severe Engine Misfire
Engines may enter a Power Reduction mode. Power reduction
limits the engine throttle opening to a “safe maneuvering” speed.
This mode is intended to allow the driver to get out of harm’s way
and to reach safe harbor for engine service.
If the check engine indicator should go on, or if the engine enters
the Power Reduction mode, you should have your dealer check
the engine as soon as possible.
NOTICE
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.
Follow the boat manufacturer’s instructions if the sea strainer is
blocked.
