Hello,

I think I really messed up my motor last weekend. I just bought the
damn boat and it's already in the shop. It's a 96 glastron gs185 with a
volvo 4.3 gs. Anyway, we were cruising along and we heard a clang clang
noise and the engine stopped. I tried to start it again and it sounded
like the starter was getting plenty of power but it just couldn't turn
the motor over. Popped piston? Broken connecting rod?

What I want to know is... could the trim have that kind of effect? I
know it was only running around 3000 rpm at full throttle...
overtrimed? I'm really new at all this, so I have no idea. The boat was
handling fine and the speedo showed about 55mph, but 3000 rpm seems low
to me at full throttle. Any thoughts here or anyone else make the same
mistake? I also wonder if the boat was just overpropped? By the way,
the temp was ok at around 150 and the oil pressure looked fine.

One more thing.. I haven't heard back from the shop yet, but I'm
already assuming it's bad, really bad... so would yall suggest
rebuilding the current motor, exchanging it for a rebuilt motor or just
going with a crate engine from gm? I found a crate engine for around
the same price as the other 2 options.

I appreciate any guidance anyone can give me... and would love you for
life if you told me it didn't sound like anything major.. yeah right!

Anyway, we were cruising along and we heard a clang clang
noise and the engine stopped.

A relatively minor flywheel-vs-starter problem could produce this, so it is
not necessarily the worst.

But do let us know the true diagnosis.
