good replacement

The thermostat worked well.

Good replacement part for my 5.7L Merc. Its takes less than minutes to swap out. Dont know about lifetime because I replace it every year anyways.

got it

Exact OEM replacement for my mercruiser 3.0. Changed out what looks to be the original thermostat installed at the factory on my 2008 Tahoe Q4 boat. Old thermostat had 07 & 160F on back of it. My thermostat was rusted the hardest part was getting the plastic retainer clip out but still was a 10 minute job from start to finish very easy install.

Only buying OEM from now on...
