Exactly.

The marinas are full of boats with iron GM, Ford, Chrysler, Mercedes, etc. engines (gas and diesel), raw water cooled, that are NEVER flushed. These engines wear out after a few thousand hours, they don't rust out.

HUMMMMMM????????? good point but I promise you, Merc big blocks NEED TO BE FLUSHED, if not you will be replacing your Manifolds and headers so fast it will make your wallet hurt!:eek: maybe its away they get replacement part business.

I hate to tell u there is a big diffrents in sitting in the water or on a lift.

If u leave it in the water ,,no air gets in there so not tooo bad ,,but on a lift or trailer and u dont flush ,,,,mmmmhhhh good luck !!!:party-smiley-004:

Thank you guys for all the different prospectives. I was worried about the internals more obviously, but I have noticed that sometimes the windshield frames and other powder coated parts seem to bubble.

I would definitely have a survey done, salt or no salt and closely inspect the drives. But I never gave it a thought about the lack of air if the boat is sitting in the water. Either way, I like the idea of a fresh water boat the best.
