Tui was launched in Hull Marina yesterday. The engine started straight away after I bled the fuel system. Once launched I checked the seacocks and the stern gland and there were no leaks. The cooling water was happily coming out of the exhaust and I set off. Before I got far the engine overheated, and the cooling water was not coming out any more. Barry, who is in charge of the boatyard operations towed me to the harbour wall in his launch. I checked the impeller and it was fine. I couldn't see anything wrong. Barry in the launch and Richard in a Rib towed me round to the berth. Eventually I worked it out. One of the hose clips on the suction side of the sea water circuit was loose. This means the pump was sucking in air and couldn't self prime. That tightened up it worked fine. One more fault I now know how to diagnose!
I just signed up to a new nice simple boat tracking site I saw on SV Delos's web site Farkwar.com. Here is Tui
