Do-It-Yourself Maintenance Suggestions - Mercury 540 Bravo Manual

Since marine engines must be capable of running at or near maximum RPM
much of the time, special valve springs, valve lifters, pistons, bearings,
camshafts and other heavy‑duty moving parts are required for long life and
peak performance.
These are but a few of the many special modifications that are required in
Mercury Marine engines to provide long life and dependable performance.
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 Mercury Marine power
package, are highly technical pieces of machinery. Electronic ignition and
special fuel delivery systems provide greater fuel economies, but
increased complexity for the untrained mechanic.
• Do not attempt any repairs that are not covered in this manual unless you
are aware of the precautions 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. This 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.
• Special tools and equipment may be 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 for the repair.
• 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 and attempt to
diagnose a problem or request the repair procedure. It is difficult for them
to diagnose a problem over the telephone.
• Your authorized Mercury Marine dealer is there to service your power
package. They have qualified factory‑trained mechanics.
Mercury Marine recommends that 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.
