Engine Alarms and Instrumentation

Digital Alarms

If, for any reason, one or more of these sensors or 
associated wiring malfunctions, the ECM’s built in 
self-diagnostic system sets a trouble code and turns on 
the Malfunction Indicator Light (MIL) or sounds a buzzer 
to alert the operator of a malfunction.
The MIL, buzzer and gauges can signal that something 
is wrong before it becomes serious enough to cause an 
expensive repair. Paying attention to the MIL, buzzer and 
gauges could also save you or others from injury. The 
MIL may be replaced by verbiage such as “Service 
Required” on boats equipped with electronic instrumen-
tation. 
The MIL or “Service Required” notice comes on when 
there is a problem with an engine function. Gauges can 
also indicate when there is a problem with an engine 
functions. Often gauges and the MIL (Service Required) 
work together to let you know that there is a problem 
with your engine.
In most cases, when the “MIL” is on, the engine(s) may 
lose some performance and/or efficiency, but remain 
running adequately. Also, the light may go out or become 
intermittent, but a trouble code will be logged for future 
diagnosis. In any case, the operator must obtain service 
by an authorized dealer to determine and repair the 
exact cause of the malfunction.
The engine ECM is programmed to control the engine 

alarm system. This system is configured to turn on an 
instrument panel mounted indicator (“MIL” or “Check 
Engine”) light, and, optionally, an audible (“buzzer”) 
alarm to warn the operator of engine problems.
If the “MIL” lights and/or the “buzzer” sounds during 
operation, the operator should scan the instrument 
panel readings for possible sources of trouble. 
Conditions that may cause alarm activation include:

•  Low Oil Pressure
•  Engine Overheat (High Temperature)
•  Electronic Throttle Malfunction
•  Engine Misfire

See Section 11: Engine Diagnostics and Codes for more 
information.
If the boat is equipped with CAN-Buss Messaging 
(Electronic Instrumentation), the main screen will likely 
display a “Service Required” message when the ECM 
records an active trouble code.

IMPORTANT:

 A failure with the Electronic Throttle 

will result in idle only operation of the engine. In some 
cases, the throttle may be reset by turning the key off 
and then restarting the engine. The operator should 
contact his servicing dealer to determine the exact 
cause of the failure.

Drive Applications

Marine Power Engines are compatible with a variety of 
drive systems. Depending on the operator’s boat type, 
the engine may be coupled to a thru-shaft mudboat 
propeller, a shallow-water gear drive, or a mudboat 
belt drive. Please familiarize yourself with your drive 
system and note the requirements it may impact on 
your engine configuration. Such things as cooling water 
supply, wiring connections and engine options may be 
unique to your installation.
