Hi, I have a boat engine question. I'm looking at a 30' Bayliner
Encounter. It's in need of one engine (350/5.7L GM) I may replace with
the same thing or go with diesels either a 6.2L or 6.5L which I
understand the 350/5.7L parts will fit. My question is do the original
engines rotate in opposite directions and if so how does one take care
of that? Thanks, Jim

Jim, I wouldn't recommend changing over to 6.5 GM's in anything,
really. There's a lot more to the swap than simply bolting it to the
flywheel housing . That's the easy part. Then you have to do a lot of
modification to the fuel system and re-routing manifolds etc. Besides.
The 6.5 diesels are low on power and eventually high on maintenance.
In the pick up truck line, they were the lowest of the diesels. they
fell below the 7.3 IH in the Fords and way below the 5.9 Cummins in
the Dodge.

Honestly, the most economical and most satisfying thing to do would be
to get another 5.7 gas and bolt it in. You can get a NEW engine for
about $1500-$2000.00

Greg could have a point on reverse rotation props, but I'm not sure
about the gear ratios in the drives.
