I am curious if anyone has ever run a make and break engine with a closed loop cooling system. Seems to me this would prolong the life of these engines. Be it a heat exchanger or cooling tubs along the keel. |

Sure,... why not. Easiest with keel cooling, other than doing something about the exhaust only the one water pump is needed (could run a dry exhaust). A heat exchanger needs a second water pump, |

Most didn't bother, but occasionally you find an engine out West where this was done. Those are almost the only engines that survive long-term. The keel cooler produces some drag of course. I wonder if a more or less straight pipe with inlet and outlet below the water line, running into and out of a heat exchanger would not provide sufficient flow when under way, and could perhaps be tucked down by the keelson, where the bilge water could help as well!  |
