The attached photos are the thermostat housings off my boat, which is a 1967 Chris-Craft Crusader 36'. The engines are Chevy 350 cid. Both are re-manufactured engines, one from Jasper the other from Blue Star (I think).
The original engines in the boat were Chris-Craft (Chevy) 327s. These re-powers happened long before my time and there is no one that I can find that knows anything about when or how or what was actually done with these. These parts may have come off the original 1967 327 engines, and transferred to the new engines.
As you can see they suffer from some serious corrosion and I would like to replace them. I’m terrified of the thought of removing them without first having replacement parts.
I would like to replace them with the same parts if I can find them, but so far no luck. I am not opposed to using a different part, as long as it fits and works fine.
I have talked to many marinas and marine mechanics and have emailed pics to several marine engine parts dealers with no luck. Everyone just says they can't find one like that in their (probably current) catalogs.
Any help anyone can give in locating/providing these parts will be greatly appreciated.
