I just removed the copper jacketed pipe and what what left of the rusted muffler out of my Pearson Triton.
I got a new MMI water lift muffler and I have a 3 questions about its installation.
1: I thought I would make some kind of wooden shelf for it and glass it in on the hull, but I'm a little worried about the vibrations and the heat because the old muffler was kind of suspended by straps and did not touch any structural part of the hull. Does my plan sound OK?
2: The old muffler had raw sea water injected at the back of it, I'm not talking about the engine cooling water, but an additional hose coming directly from a thru hull, I'm not sure I understand why, maybe for additional cooling ?Anyway I would like to do away with that because it's not a proper seacock, just a plastic thru-hull with a garden hose type faucet that's half rusted out. I would like to get rid of it and plug that hole below the water line.
Is that OK? of do I need the extra cool water to cool the exhaust?
3: the outlet on the MMI muffler is 2''ID. Would it be ok to convert that to
1-5/8'' since that's what I have right now or should I get some new hose and a bigger thru-hull at the transom?
