Thanks for the replies guys -- much appriciated.

It sounds like the consensus so for is contender 2, and I would totally agree with you if it was not for posts elsewhere talking about the risks of corrosion/freeze-cracks in the water jackets for marine engines.

If I do go with the marine engine, I'm assuming the recommendation is to get it pressure tested as well as magnafluxed -- what kind of pressure is considered a pass?

Thanks,

Peter
