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
machinery. Electronic ignition and special fuel delivery 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
(Cautions 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
service manual outlines the correct procedures to follow. It is written for the trained mechanic, so there may
be procedures you dont 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 dealers
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.
Your Authorized Dealer is there to service your power package. They have qualified factory-trained
mechanics.
It is recommended you have the dealer do periodic maintenance checks on your power package. Have them
winterize 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.
