Looked at my local Auto Zone and no Chevy thermostat is small enough to fit my straight 6 Mercruiser thermo housing.

Is there an automotive one that will fit?

i don't know about an automotive one fitting, but...

i do know you don't want an automotive thermostat in your marine engine

your marine engine needs a 143 degree thermostat, whereas an automotive thermostat will allow the engine coolant to reach near boiling temp - way too hot for a marine engine

i dunno if an auto one will work or not. do they come in the 140* range? assuming ya got rwc, that's what ya need. marine tstats come in this value...

i R&Red my tstat this year. went up to my local mercruiser store and they had just what i needed.

edit. dubs is right. the exact spec is 143* tstat for rwc..
