Do-It-Yourself Maintenance Suggestions
If you are one of those persons who likes to do-it-yourself, here are some suggestions for you.
•
Present-day marine equipment, such as your MerCruiser power package, are highly technical pieces of machin-
ery. Electronic ignition and electronic fuel injection systems provide greater fuel economies, but also are more
complex for the untrained mechanic.
•
Do not attempt any repairs which are not covered in this manual unless you are aware of the precautions (“Cau-
tions” and “Warnings”) and procedures required. Your safety is of our concern.
•
If you attempt to service the product yourself, we suggest you order the service manual for that model. The ser-
vice manual outlines the correct procedures to follow. It is written for the trained mechanic, so there may be
procedures you don’t understand. Do not attempt repairs if you do not understand the procedures.
•
There are special tools and equipment that are required to perform some repairs. Do not attempt these repairs
unless you have these special tools and/or equipment. You can cause damage to the product in excess of the
cost a dealer would charge you.
•
Also, if you partially disassemble an engine or drive assembly and are unable to repair it, the dealer’s mechanic
must reassemble the components and test to determine the problem. This will cost you more than taking it to
the dealer immediately upon having a problem. It may be a very simple adjustment to correct the problem.
•
Do not telephone the dealer, service office or the factory to attempt for them to diagnose a problem or request
the repair procedure. It is difficult for them to diagnose a problem over the telephone. A doctor can’t and won’t
diagnose your illness by telephone; he must examine you personally, just as a mechanic must examine your
power package.
•
Your Authorized Dealer is there to service your power package. He has qualified factory-trained mechanics.
It is recommended you have the dealer do periodic maintenance checks on your power package. Have him winter-
ize it in the fall and service it before the boating season. This will reduce the possibility of any problems occurring
during your boating season when you want trouble-free boating pleasure.

Diagnosing EFI Problems
Your Authorized MerCruiser Dealer has the proper service tools for diagnosing problems on the Electronic Fuel
Injection (EFI) System. The Electronic Control Module (ECM) on this engine has the ability to detect some prob-
lems with the system when they occur, and store a “Trouble Code” in the ECM’s memory. This code can then be
read later by a service technician using a special diagnostic tool.
