Keel cooled

Recommended Posts

In almost all cases the area of keel used as a heat exchanger is lager than that required for the engine in use, with the thermostat in the header doing most of the work, plus a valve in the line to allow a higher flow of cool water through if / when you venture into warmer waters.

I have had keel cooling for many years. The system has done 1000s 0f NM with no problems.

I also have a dry exhaust. Even in the hottest water it has never been a problem. (In fact I have looked at putting in a bypass valve to increase the engine temp.) The benefits are many, one of which is being able to motor in waters that have a lot of "stuff" in them. 

Being able to use a completely un-marinised engine can save thousands of dollars, which in turn can help pay for the keel cooling. The engine parts are then cheap , off the shelf "normal" engine part costs. I run an Isuzu industrial engine.

Darned right!

I have my first experience of keel cooling in the canal boat and would be most reluctant to go back to a raw water via heat exchanger system. It's as easy as running your car - check the header tank now and then and that's it. No dripping Jabsco type raw water pump to fret about (make sure you have a spare impeller), no need for a raw water strainer to clean. No need to keep an eye always on the temperature in case some bit of gunk gums up the inlet skin fitting...I realize the european canals are a bit grubby and a different environment to here, but we regularly pass raw water cooled boats stopped on the canal side whilst the owner scrapes the muck out of his strainer over the side. Keel cooling for me.
