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
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.
Running at low speed, as the fishermen tend to do with all that trolling, keeps the motor too cold. That damages the pistons/ rings/ walls/ etc. Hard running keeps her warm enough to avoid that.
