Engine Protection Mode
In a low oil pressure or engine overheat situation, the
engine will trigger the Engine Protection Mode (EPM).
In such cases, if an acoustic alarm has been installed
with your engine, it will sound to notify you of a mal-
function
(3)
.
If the engine triggers protection mode, its speed
(RPMs) may be reduced or it may shut down, depend-
ing on the engine equipment and circumstances.
Under most conditions, engine operation is limited to
2500 RPMs or less
(4)
. When the engine enters EPM,
there will be a temporary reduction in power until the
problem is resolved.
We strongly urge you to bring
the engine to idle to investigate the problem.
If the
acoustic alarm stops sounding, the malfunction has
been cleared and the engine may now be operated
normally.
Use the oil pressure and water temperature gauges to
verify a problem exists, then inspect the engine crank-
case for proper oil level and check the water inlets for
obstructions. The low oil pressure/engine overheat
problem must be corrected before the engine will
return to normal operation.
To reset the Engine Protection Mode after the problem
is corrected, reduce engine speed to idle, allow the
engine to cool, and then continue with normal opera-
tion.
If you are unable to locate and resolve the problem,
you may be able to continue operating the engine at
above idle speed, keeping in mind that the acoustic
alarm will continue sounding and the engine speed will
remain at a reduced level.
NOTICE!
Continuing to run the engine, with EPM
active and without correcting the cause of the problem,
may result in engine damage or equipment failure
which may not be covered by your warranty.
If the problem continues, contact your Volvo Penta
dealer and have the engine inspected.

3 . While Volvo Penta provides an audible alarm with every engine,
its installation is determined by the manufacturer of your boat. If your
boat does not have an audible alarm available, we strongly recom-
mend that you contact your dealer to have one installed.
4 . For mild engine overheating, engine speed reduction will be 3500
RPMs.
