I've got Cool-Craft heat exchangers on my boat and I'm trying to find a replacement thermostat for without any luck because Cool-Craft has gone out of business.

The Cool-Craft system has the thermostat built into part of the exchanger instead of the thermostat housing on the block so it's not gonna be a standard Mercury one that I need.
What I'm looking for is a 160 degree thermostat that's got the pressure pull off on the bottom.

I've tried going to NAPA but they have no way to look up an aftermarket part and did not want to take the time to look through what he had in stock to try to match something up.

Does anyone have any suggestions?

Thanks
