Thanks, Sebatian.  Good idea to check the elbow.  Will do that first.

How much water flow do you get out of the back?  I’ve never measured it very scientifically, but there should be a steady and pretty substantial stream of water coming out.  Another thing to check is bits of an old impeller stuck in the elbow of the sea water pump – on my boat that was causing a substantial blockage.  And much easier to check that first before you pull the heat exchanger.

Listees,

 

Need your expertise........ We have a 1986 C27 with a Universal M-18.  After about 2 hours of motoring, we over heat and the warning buzzer goes off - around 200 degrees F.  I've checked the fresh water intake screen and that's clear.  I've also inspected the freshwater impeller and that is in very good condition.  I checked the coolant when changing the oil in June and was surprised to see it low.  Added about 3 cups.  It's still over heating after an extended period of running.  Where else should I be looking? 

 

Thanks,
