I am purchasing a used 1988 boat with OMC V8 FWC engine also 1988 and
would like to start off with brand new manifolds and risers. But I have
not done this before. Has
anyone done the changing themselves, or is this a job best left to the
boatyard/mechanics? Any experiences, positive or negative, doing
this job will be appreciated.
Thanks

Do they really need replacement?

Chevy or Ford? If it's a Chevrolet, I would consider looking into
"Stainless Marine" brand stanless exhaust components. Cost a little
more, but weigh a lot less and breathe much better.

It's pretty straight forward to do the job - tough part is the weight of
iron manifolds in a confined working space makes them somewhat unwieldy.
