Single or twin engines? Shafts or legs?I’ve got a nanni 4.380 and my maximum revs are suddenly 2900 making speed 12knots instead of 3600 and up to 20knts - I’ve done all the checks recommended on this thread but nothing is solving the problem. I’ve booked in for lift out but am doubtful that light fouling I can observe at low tide (drying harbour) would cause such a massive drop in performance. Any ideas?
