Have the manifolds and risers pulled and inspected. At that age, if they
haven't been replaced they probably need it. Neglecting this little item
will dump water into your engine, causing an untimely death. Otherwise, oil
and filter change, change the RW pump impeller, change the antifreeze
solution if it's FW cooled, and get a service manual and make up a
checklist.

I am new to boating and purchased a 1996 model with an 5.7L inboard last
spring. What maintenance do I need to perform after de-winterizing the
boat?

Oil Change ( I have no idea if/when the previous owner had it changed)
Belts?
Hoses?
Any other fluids, filters, or things that need to be changed/adjusted?

Talking this over with a longtime boat mechanic/dealer friend of
mine, he said that this is primarily a concern with sal****er I/O's
which pump sal****er to cool the manifolds. According to him, in
freshwater it isn't a problem.

Has anyone running a Mercruiser in freshwater had the problem of the
Manifold and risers rusting through allowing water to be pumped onto
the exhaust valve? If so, I'd really like to hear about it before it
happens to me!
