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.

Fits 1988 Sea Ray V-135 2 stroke (Mercury)
For those of you with the 135 hp
mercury that was branded as the "Sea Ray 135" and paint matched to the boat (i.e. Seville's and some others) this is the 147 degree thermostat for that motor. My Seville is an '88 and It's difficult to cross reference the serial numbers on those motors when searching for parts. Only buy Quicksilver parts for these motors. Happy to find them on Amazon because Boats.net as an example, is not clear on what you're getting.
