Has any one done this? Do any engines use or offer this as an option?
Other than the obvious "Engine will drown if pump on and engine
not running" (or any thoughts on how to mitigate this problem) are there any other down sides?
The replacement engine
I am looking at (rep[lacing the old and fully seized Ford Dorset) Has come from a keel
cooled canal boat. Keel cooling
uses a fresh water coolant
so no water
pump">Raw Water pump is needed. The builders (Lister) do not seem to offer this as an option, but the rest of the engine is in great shape. I can get a heat exchanger
with no trouble but I suspect that a Raw Water pump
is going to be a bit sticky.
