Never had the soot problem prion to going to the Bahamas last year. A little blue smoke on start up was normal. The black soot is not, so we will see what an injector service will do.
Scots actually but I can see why you would think Irish. It is the name of the boat but actually an anagram of our kids names. BEn,JAde,SUmmer,Sasha. It seemed an appropriate name.
Keep finding black soot on the transom after a run.
Engine runs fine with no overheating, no fuel in the oil or coolant. Prop is correctly sized, but do not usually run over 1800 rpm.
Ideas welcome.
