yes, the motor was designed to run at a certain temperature, the thermostat accomplishes that. it can run too cool, causing the motor to foul plugs, it can also allow water to run too fast thru the motor, not taking the heat away, thus the motor runs hot, and you end up with a mass of unusable metal. use a tstat.

Also, if you run your motor in salt water, make sure you run it in fresh water for at least 10 minutes to flush it out. especially if you're going to store it for any period of time. I have seen many motors, where the cooling jackets are completely packed with corrosion, because they weren't flushed properly.

Heh, the thermostat is the least of your worries. That motor is on it's way to the bone yard, what with the metal separating from the sleeves. Hey, 40 years in Florida water ain't bad!!
