At the start of the season I moved my boat fromt the Blackwater to the Clyde. The engine (a 3 cylinder Yanmar) was fine at the end of last season and was winterised and recommissioned for me prior to the move. It now emits white smoke - an initial burst on starting, then nothing until it has warmed up but produces copious amounts cruising at 2000 revs.
First thought was water in fuel, but water trap OK, and no signs of cylinder head gasket problems - internal coolant level OK and oil looks fine. My local marine engineer recons it is just to do with the colder sea water giving a similar effect to a car exhaust on a cold day. However I'm not convinced and the Clyde does not feel significantly colder than the North Sea to me.
Any thoughts or suggestions. The engine seems to be running OK but I don't want to just ignore what might be a problem.
