I spent the past weekend working with Bruce Schwab on his wood, foam and
carbon fiber Open 60, Ocean Planet.

In preparation for the Vendee Globe in November, he is paring as much
weight from the boat as possible, and one thought is changing the Yanmar
3GM diesel to raw water cooling, thereby eliminating the second pump,
the heat exchanger tank, etc.

I have a few friends with the 3GM raw water engine that would probably
happily swap with him ;-)

I seriously suspect any engine shop would trade you even AND maybe ship
it for free.

And on the cold water concerns in a later post: That's what thermostats
are for. Yes, it'll be cool at first, but I suspect Bruce will run the
engine for relatively long periods at relatively high power levels or
he'd have gone to the 2GM or 1GM.
