Re: catalina27-talk: Over Heating

[Michael Munn]

Thanks, Don.  I seem to be getting plenty of water at the discharge, so I'm leaning towards the heat exchanger.  I finally figured out how I was going to remove it and then realized it was probably full of coolant.  You have to drain the system first don't you?

The raw water intake clamshell under the boat could be clogged.  Most likely, your heat exchanger needs cleaning.  You can take it to a radiator shop for cleaning, or do it yourself with muratic acid, but be careful, that is nasty stuff.

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,
