Based on preliminary advice from 2 members of this NG I may be looking at
replacing the exhaust manifolds and risers on my 4.3L 1997 Volvo Penta.

The engine compartment on this boat is small and even an oil filter change
is difficult.

Knowing that does the replacement of the manifolds and risers mean the
engine has to be pulled? The boat is a 1997 Glaston GS209.

TIA!


I'm in the process of doing this on my SeaRay 300 Weekender with twin
5.7L's, and I'm of course not pulling the engines, even though they
are put in with a shoe horn. If I pulled them, I wouldn't have
anything to lay on! 8)

Having the engine on a stand would make this a piece of cake,
especially if you break a bolt or two. If everything else is OK, I'd
avoid pulling the engine, as that can open up its own can of worms.
Even though space looks tight, you should be able to access all of the
servicable items.

I would avoid using Sierra products, as the last set of risers I
bought from them were very, very poor. The casting quality was awful,
and I refused to install them. The best casting I've seen so far is
from Aqua Power, but Sierra bought them and the Aqua Power brand was
discontinued, along with their superior castings. You should be able
to find a new set on the web though. I have also found the OEM
Mercruiser products to be of good quality, but if you plan to buy them
locally, you'll pay through the nose for them.
