Re: catalina27-talk: Over Heating

[Don Brooks]

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,
