2003 Sundancer 360, got an overheat on PORT engine during a trip yesterday when running at 3200rpm. Shut the engine down and continued our trip on the STBD. After about 15 minutes restarted the PORT and ran the rest of the trip at 2400rpm. Temp rose to 176 and held steady. STBD was running about 166.
My first guess is a bad water pump impeller. The only thing giving me pause is it has only been about 18 months since I replaced both water pumps and impellers. Total run time since then is less than 50 hours. Very little use over the last 8 months and basically no use the last 6 months other than to start the engines every 2 months.
Risers and manifolds are coming up on 4 years old with about 100 hours of salt water use.
Is my guess at the impeller reasonable or should I be concerned about something more significant.
Thanks.
