Hi again, I'm still trying to get the boat to run nicely, apart from the plumes of smoke, which I publicly apologis for, (I'm hoping it's to do with the prolonged bedding in period and that it will settle down to an acceptable level once the boat has a few more miles under it's belt) it still overheats. I think an airlock got purged during this afternoons trip as, initially, the first skin tank was warm, whereas the second tank was stone cold. After this airlock was belched out, the second tank started to warm up, but by then, I'd discovered the Cambrian Wharf visitor moorings were full, so headed back to Sherborne Wharf. Basically, I think the coolant is struggling to travel around the circuit because the engine pump can't push the huge volume of water around the numerous 90 deg bends in the circuit between engine and skin tanks. Does it sound sensible to add another pump between the starboard and port skin tank? I'm thinking of fitting a thermostatically controlled electric one as I think it would be easier to plumb in, but, if a mechanical pulley driven one is more suitable, I'd go with expert opinion. If this is a sensible mod, what pump make/type would get your vote? The external hoses are all 32mm id except for restrictions into and out of the engine and gearbox oil cooler heat exchangers. At the moment, and it was only a very short trip, it seems that running at anything over tickover causes overheating but it was stable cruising at tickover. Failing that, is it possible to convert to raw water cooling or is that just changing one set of problems for another? Thanks in advance Robert
