Fired up the old Carver for the first time in...uh...too long and noticed the stb motor was heading for overheat pronto.
I haven't done any real troubleshooting yet but I had a temp gun handy so I started comparing things between the two motors. The one thing that stood out was that on the overheating motor the heat exchanger was much cooler than on the good motor. This made me think I must not be circulating coolant through it. The reservoir is full and the belt is spinning the circ pump, so I'll check for a possible blockage tomorrow when it's cold.
I got to thinking though, have any of you had a circ pump fail to move water but not show any outward signs of trouble?
This is on a fresh water cooled Crusader 454 v-drive.
