120 degree is kind of low temperature and is supposed
to be for people who like to run the motor at slow speed -- as in
trolling.

Trolling? Hey! You could run that motor on rec.boats!....(c

Let's step back a moment.......

How old is this motor? How many years did it run without overheating on a
thermostat marked "120"? How many heavy repairs and blown powerheads did
you say it had had?

If the answer is long years and little trouble....why screw around changing
what works great?!

If I understand you correctly, you are saying that the 120 degree
thermostat has probably helped the 1995 old motor to keep it from
overheating. Again if I understand this correctly, I could have used a
higher temperature thermostat if my outboard motor was a recent model;
but given the fact that my motor is old, I am better off using the 120
degree low-temperature thermostat to play this safe, right?

I don't know the track record of this outboard motor because I bought
the boat with the motor last fall and the boat has been sitting in my
driveway for one year unused. Therefore, I don't know if the motor
runs fine or not. The only thing I know is that the boat/motor was
working fine when I had a sea-trial on it; the boat could get on plane
with a party of 4 very quickly. I guess this means I should leave
"good enough" alone and stick with the thermostat with the same
temperature rating.

Thanks for your advice.
