Motoring back to port the exhaust water flow was diminished and the temp was fluctuating from 140to 180 and back. When we got to the harbor and reduced to idle the exhaust water stopped completely and I immediately shut it down. I figured it was an impeller and removed that to find it slightly worn but in tack. I put in a new impeller, checked that the overboard pick up was providing water and fired it up. No water being pumped out the exhaust. Anyone have a clue what the problem might be ? It is insalled in a 78 C&C 29.
