Hi clever boaters,
I have a 30hp evenrude. Runs sweet as a nut all round. However at wot I can only achieve just over 4000rpm? The book say between 5200 & 5800rpm? I’ve checked everything I can....timing is good at wot, all ignition checks out? Could this be a prop issue? I’m running a 10/13, which is within the book recommendations. I guess I could go 10/11 which may give me 400rpm more but I’ll still be below the books minimum? I’m getting approx 15mph which seems underpower for my 15ft sea hog? Could the taco be inaccurate?
I’ve bought a hand held taco to test & calibrate.
Apart from the prop idea I can’t think of any other reason why I’m having this problem? Could a coil be failing at high rpm? All is smooth & solid but the figures are low?????
any suggestions would be greatly appreciated.
faithfully Mike
