Specs At A Glance

Good To Know

Q: Will this gasket fit my Mercruiser 3.0L? A: Yes, this gasket is designed for 2.5L and 3.0L Mercruiser engines, but always verify your engine's serial number for exact compatibility.

Q: Can I use this gasket with aftermarket thermostat housings? A: It is engineered to match OEM dimensions, so it should work with most standard thermostat housings, but confirm the housing's mating surface.
