Engine Troubleshooting Guides
The following troubleshooting guide is provided to help
you isolate a malfunction of one or more of your boat’s
systems. After determining which systems are affected
by the malfunction, refer to the individual system trou-
bleshooting charts to isolate the specific cause.
This guide was written to help you trace the symptoms
of the trouble to the source, without having to read
through and prove every possibility. Much of the infor-
mation here will be familiar to well informed mechanics.
The greatest aid to solving a service problem is infor-
mation. Start gathering information and keep a detailed
record of the symptoms of the malfunction. Keep a
record of pertinent facts, such as:
•
When did this trouble start?
•
How was the boat loaded?
•
Did the trouble occur suddenly or did it become
apparent gradually?
Whether servicing the boat’s systems yourself or hav-
ing your product serviced by a certified Volvo Penta
dealer, you will need this record of information to iden-
tify potential causes of the malfunction.
Keep in mind the fundamentals of engine operation, all
of the following must be present for the engine to run:
•
COMPRESSION - Mixture inducted into cylinder
and compressed.
•
SPARK - Proper intensity at the proper time.
•
FUEL - Proper mixture of air and fuel.
•
EXHAUST - Clear of any obstructions.
•
COOLING - water is needed to cool the engine.
