A lot of peeps on OSO out of TX, depending where its located maybe one of them could help out ? look for these wires on the intake and crank shaft and other places

I guess the real thing that I'm afraid of is the headers. I know that the guy that has the boat now runs it in fresh water, but something tells me that the original owner had it in salt for 200 hrs. I guess I just don't understand how saltwater hurts stainless steel. Or is it that they just crack from vibration etc. I just know that CMI headers are very expensive to replace.

Than k you, yes, I know what the wires are. It's just like pulling teeth trying to get a pic out of these guys.

the condition of the engines all depends on how they were taken care of, being closed cooled is a big plus when running in salt, flushed after use is key, salt water will erode, eat stainless over time

Hopefully somebody sees this that has one of these motors, but shouldn't the exhaust manifold bolts be stainless?

It looks to me like those headers are the updated style with the leaking at the flange addressed. I doubt the original header bolts were stainless - don't know for sure though.

Yes they can. My Rinda scan also showed a very small amount of time over 5,499. The engine starts reducing power at 5,400 but it is still possible to rev beyond that.
