Hi Brian,

I've done conversions on automobile V-8's and run them for years..

I have a 350 GM in the same boat I built in 1978 (25th anniversary last
Summer on Lake Champlain).

The 'conventional' conversion adds exhaust manifolds, water
pump/plumbing, flame arrester, drive train solution, and motor mounts.

Since it's been so long since I've done one, and I'm interested in 1 or 2
small diesels for a slower bigger boat, I wonder what people here have
done.

In article ,

I've done an engine aero conversion, and there is more to it than
meets the eye, so I am leery.
But thinking on your suggestion, we are talking cooling and we are
talking forward/reverse. Think you could handle those?
If you can, VW would be very, very promising.
Or howz about a Mercedes?
