Bought a new Crestliner with the new Honda 150HP and can't get the engine to run past 3000 rpm. Dealer sold engine with a 19 inch prop so thought that was the problem. Went to a 15 inch and still have the same problem. Is the engine programed to only run 3000 rpm until it has a few hours on it then rap up? Dealer doesn't have any idea what the problem would be. He ordered a manual to help in trouble shooting. Any ideas or info would be helpful.
