for possible causes and
solutions.
NOTICE!
Ignoring an overheating situation can cause
engine damage or failure. This may not be covered by
your warranty.
If the situation persists, contact your Volvo Penta
dealer for assistance.
Electric Fuel Pumps
EFI engines have two electric fuel pumps, contained in
a fuel cell on the front of the engine:
•
A high-pressure pump
A
to supply the fuel injectors.
•
A low-pressure pump
B
to bring fuel from the boat
tank to the engine.
Both pumps are protected by a common 20-amp fuse
and are controlled by a relay. See the next section. The
pumps will operate only when the engine is cranking
or running. If a pump is not working, check the fuse and
replace if necessary. See your Volvo Penta dealer if
further service is required.
The fuel filter
C
is also mounted to the fuel cell. To
change the filter, see
NOTICE!
A loud whining noise at idle may be due to a
restricted fuel filter causing a noisy fuel pump. Oper-
ating the engine with a restricted filter may damage the
pressure regulator or fuel pumps. See your Volvo
Penta dealer if the pump makes an unusual noise.
Circuit Breakers and Fuses
The engine’s electrical system is protected against cir-
cuit overload by fuses and circuit breakers. Engine
electrical circuits may also be routed through relays.
All relays, breakers, and fuses for the driveline are
contained in a single fuse box. The box is covered and
is mounted on the top of the engine. If electrical sys-
tems such as power trim or ignition are not working,
check this box as a first step in troubleshooting the
problem.
