Taking the advice to run the engine hard I opened up to 2500rpm yesterday (normally cruise
at about 2000-2200) and within a few minutes the the temp had risen to 180f and the temp alarm
went off (actually I wouldn't have noticed the alarm
if I hadn't been watching the temp - note to self - replace!).
180f is within my operating range so either the temp alarm sender is miscalibrated or the temperature gauge. If the engine is overheating
then I suspect the crimped elbow
in the water
heater extension to the coolant
system as plenty of water was coming out of the exhaust
. The alarm continued to go off even after backing off though the temperature gauge returned to normal pretty quickly. Kept me checking the old girl every five minutes...
Not really looking for answers here, just wanted to share the joys of being a noob with a new old boat
One little operation leads to suspicious sender behvaior, alarm behavior, coolant
behavior, perhaps gauge behavior and a slightly nervous GF - good thing I like this stuff! Other than the small alarm issue we had a great little nose around some potential weekending anchorages
and a glorious sunny sail!
