Engine and keel-cooler both, yes? Last year when we flushed our system with radiator cleaner, we just ran city water into the keel-cooler long enough to see only clear water coming out the other end. Most engines drain pretty well on their own. Need to run the bilge pump of course! :)
The radiator flush we used worked great. There wasn't a bit of rust scale in the engine block we we pulled it apart for rebuild this fall.
