Thanks for the reply which pretty much confirms I don't know what it is. The pipe is for water cooling the engine - a sort of water/water heat exchanger for an i.c. engine. Tube has connections fore and aft in to the hull forming part of a closed loop system but un-pressurised. Presumably there should be a vent pipe or header tank. All guess work as the engine is not present - probably go brushless. And thanks Tony, more confirmation. I hope someone or the previous owner, I assume somewhere in Kent with the Headcorn connection, recognises it. Thanks, J
