Nothing to be scared of. Closed loop cooling and flushed after use.

This boat and any salt water boat with fresh water cooling/closed loop will look and perform the same way as a fresh water boat. Especially if it's maintained properly.

This one was dry stored, cleaned and flushed after every use. It looks and is maintained better than most including freshwater boats. If you don't agree I'll give you $500 for the travel.

New question.....where is the rear transom shower located?? Do they all have them?

On the transom under a lid, it was an option.

You should look hard at Vyper 340's boat, you will not find a nicer and we cared for boat. I IS worth your time. Fresh water cooler motors run antifreeze, not salt!

I have been speaking with him.....looks like a hell of a boat!!
