That's also a consideration for rebuild of the existing engines. I'm assumng this is a salt water boat. Not sure I'd want to invest in quality rebuild of a raw (salt) water cooled block. Maybe consider short or long block (as apporpriate) with your old bolt-ons and a San Juan fresh water cooling kit. Probably need to consider fresh exhaust risers while you're at it.

"I thought about fresh water conversion, but I'm not sure it's worth it???"

Back when most boats were sea water cooled the expected engine life was about 7 years.

With engines that were expected to run 1,000 or 1,500 hours , engine changes were fairly common.

Either worn out or rusted thru.

Just look at the adds in a 1950 Yachting mag.

FW cooling is not hard or expensive , esp if you can find used heat exchangers .

How often would you take it out?

Can you easily haul the boat out(you'll need to if you want to replace them)?

Do you want to go fast?

This is a trawler forum but i'd start collecting parts to put together 2 350 chevy's. I'd put them on stands in my garage and check them out top to bottom to get everything as ready as I could for when I haul out.

I'm not a fan of 454's personally and would rather lose the speed.

Another option would be a bracket with an outboard.

I wouldn't consider diesels unless you are almost constantly on the move.

"They aren't going to last as long, but you get a much lower initial cost at purchase."

With modern gassers going 4,000 hours and rec boaters doing 200 hours or so a year , 20+ years from now when the gasser needs replacement , the air police will probably decide the engine you require.

Brand new crate engines will be different then , but probably still the lowest cost for R&R.

You could always get creative. These people got this boat home a long distance with this setup(the boat is beautiful now BTW).


Nice photo out of respect.


A boat doesn't become a dock potato if it's being used. With working engines would it be taken out often enough to make it worth it?


After googling the boat it looks like a decent candidate for diesels. I'd buy a pair of used ones for around $10,000(probably a pair of volvo's because they are plentiful), paint/freshen them up and swap them in.
