I was speaking to someone who has a used drop in engine for sale, with just 100 hours on it. He claims it is a "heavier duty" engine, in comparison to a standard 5.7 Mercruiser.

Just wondered if anyone else had heard about these and if so, what the differences were?

Thanks,

Those are special engines for "big water."

Any idea what makes them "special"?

I service a twin with those engines, other than being a inboard application usually with the FWC package, there is no difference.Just remember if it`s from a inboard with a aft mounted starter you will need your flywheel

Thanks for the info guys!

I'm looking at replacing one of the engines in a twin screw Chaparral [5.7 I/O] I just bought. It sounds like this engine would be ok after a few parts are swapped over.

Thanks,
