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.


Exactly what I would do. If the motor ran 10 years at 120 degrees and is
still running good at 120 degrees, why screw around with success?

Yes, you are right. I just bought a new thermostat from the dealer. I
asked the dealer about this, and he entered the serial number of my
motor, and found that mine should use 120 degree thermostat. This
settles the issue.
