Hi all:
I have a 1991 Yamaha 150 on my Grady White Tournament. Last November, I was running it on the muffs in the driveway when the overheat alarm began. Temp gun indicated 200F. Located a kink in the hose. Replaced both thermostats to be cautious. Impeller had been changed 9 months earlier. Today started on the muffs and after 5 minutes at idle the temps were as follows, 89,91,94 bottom to top on port side and 89,92,107 starboard side. Engine appears to run normally. Seems to be a more noticeable split on the starboard side...Should I be concerned????
