Outboard thermostat
Works fine. A little pricey but better to buy the best than risk a cheap failure and destroy your engine like i did once.

Functioned as advertized.
Installed these in my Whalers 96 200 Offshore. No issues, used permatex gasket compound on aluminum engine parts after cleaning with fine brass wire wheel.
