Anyone know if the national chain stores carry a marine thermostat for my pcm 351? I believe I have the 143* stat. Looking for a gasket and thermostat combo. I know skidim has them, but I'm trying to get the boat together today. Maybe any other cross references or anything of the sort? Thanks for the help..

I'm sure Napa would have one. Take your old one in with you, they can probably just match or cross the numbers.

Automotive thermostats are fine, but they don't have bypass holes in them. Make sure you drill a hole the same size and in the same place as the old one.

I believe the only Tstat that needs those bypass holes is the LT1.

Yeah the one I pulled out of the boat doesn't have any bypass holes. There's actually an entire bypass tube that routes water when the t stat is closed. So automotive is ok?
