Fit Mercury 150 saltwater 2 stroke great!
These fit my Mercury 150 perfect. Took it out for a test run and engine ran great with no overheating issues.

Fit perfectly
Truly impressive, bought these and a set from a us boat supplier a thermostat made in the USA . They came with the gasket separate . I could not figure out how to put it together . I used these in my mercury optimax 135 hp . They fit perfectly and appear to be working great at a quarter the cost .
