I used a cheap thermostat and gasket and it didn't fit properly and it leaked. Just use the factory MerCruiser gasket with the brass inserts for temp. Just don't use cheap knock off shit unless you like doing things twice, learned my lesson
I take my thermostat out every year to winterize on both my boats with IO's and make replacement gaskets out of regular gasket paper and never had one leak.
