Default How to change manifolds and risers on an OMC V8

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

Depends on you mechanical ability, but I would consider this job
"semi-easy" on the scale.

Disassembly is a breeze. Simply...

1. Remove the exhaust rubber "pipes".
2. Remove rubber water inlet hoses.
3. Remove risers from the manifolds.
4. Remove manifolds from block.

Assembly is where some care is needed. You didn't say why you were
doing this, but if the parts are new, you need not worry much. (if you
were replacing the same, or used units, you MUST verify warpage with a
straight edge). Just make sure all surfaces are clean and free of any
oil and debris, make sure all gaskets line up correctly, and since it
appears this is work you don't normally do, I would recommend a torque
wrench to ensure proper tightening. Reverse procedure above for
assembly.

Good luck.
