I am not trying to stir anything up by asking this question, but because
the water cooling passages are by design so narrow in the vicinity of the
thermostat on my 1995 Merc 60hp 2-stroke Bigfoot, and small debris was
constantly lodging itself on the waterpump/impeller side of the thermostat
I decided to just run without it. I have been doing it for two seasons
now. I measured the water temperature at the powerhead with a laser unit at
about 90 degrees. I am getting ready to advise that my neighbor do the
same thing and I just wanted to hear some comments first. What will it
hurt?

Running without a thermostat can cause air to get in the fuel lines.

Just kidding.
