Could someone be kind enough to give me a parts number or source for  Thermostats for a 1980 Chris Craft 454 CI engine(s).

So far all I have been able to find are Mercruiser applications. Granted the thermostat may be the same, but I would feel better if someone could verify.

Jim was dead on the money. Harpur knew exactly what I needed and had them in stock. My boat has a closed system and according to Harpur it takes 140F (I think officially it's 142F) I have 2 on the way.
