Do‑It‑Yourself Maintenance Suggestions
Present day marine equipment, such as your Mercury 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.
If you are one of those persons who likes to do it yourself, here are some suggestions for you.
• Do not attempt any repairs unless you are aware of the Cautions, Warnings, and procedures required. Your safety is 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 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 to 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.

Inspection

Inspect your power package often, and at regular intervals, to help maintain its top operating performance and correct potential
problems before they occur. The entire power package should be checked carefully, including all accessible engine parts.
• Check for loose, damaged or missing parts, hoses and clamps; tighten or replace as necessary.
• Check plug leads and electrical leads for damage.
• Remove and inspect the propeller. If badly nicked, bent, or cracked, contact your authorized Mercury MerCruiser dealer.
• Repair nicks and corrosion damage on power package exterior finish. Contact your authorized Mercury MerCruiser dealer.
