Merc 115 hp vibration in neutral on start up... Help!
Like new Merc 115, 4 stroke, command out board, two years old and very few hours (pontoon boat). Place in neutral, start up and experience vibration and "lopeing" and same when put in gear. Can increase rpms in neutral and higher rpms will clear and run great. Took off prop and checked for line.. clear. Ideas of problem appreciated and suggestions for repair. Thanks, Michael
