120 degrees is to avoid salt buildup. prime temperature is hotter 180+
A cold engine will wear it self out.
88, what do you mean a cold engine will wear itself out?
Where can I find a hotter thermostat for a 40 merc?
i found an automotive one that fit the omc
Which auto therm is that?
actually i cannot remember which one it was. this was back in the lat 80s. i do remember opening a few boxes at the auto store to find one that matched the diameter and depth for the 49ci omc.
All I know is that the fishermen here that pull the stats wear a motor out way faster than those that don't. A motor has to be at temp to make power. I run 1 1/2" above the bottom, with a factory stat.Quote:
