Force 150 HP Operating temperature

[force150]

I just rebuilt my 1990 force 150 hp engine. The temperature buzzer was shot so I put a temp gauge on. What is the normal temperature range for a good running engine? I am assuming if I go above 160F things will not be good.

A few degrees warmer than your thermostat!

140* - 160*f is ideal operating range.<br /><br />c/6<br /><br />Hooty

would this be the same ideal temp for a 1989 85 horsepower force? and if so could you pinpoint a place that i could buy a guage from? ive been looking all over and none of them are sensitive enough
