Review on 67F 12411 01 00 Thermostat Replacement Yamaha F150 by Kyle Deel

This differs from the Yamaha OEM unit. All differences are visible in the photo. I wasn't paying attention and didn't notice the differences in the photo. 1. A little longer. 2. Drilled into the top I would call a drain hole. 3. The rubber gasket does not cover the thermostat neck and is a little thinner than the original. (probably doesn't seal as well as the OEM) Mine isn't leaking yet so we'll see. I suppose as long as it opens fully at 60C and doesn't leak or fail prematurely, it'll do for now. Even if I don't like the differences. I will not buy this again.
