Have had the boat for only 2 months now and everything was going perfect, I recently replaced the prop and after a couple trips out the motor wont go, WOT the boat will only get to about 2k RPM and do about 7MPH, With just buying the boat don't really have the extra expense of taking it somewhere unless need be, any help would be greatly appreciated. The first time i noticed it i just held the hot foot down and after about 15 seconds the motor got up to what it was suppose to be doing RPM and MPH, then slowly after it took longer and longer until now when it wont get up and go above 7?
