It started out only doing it at full throttle but now it is jerking even at low speed. We have had a tune up and replaced the forward gear and the prop. But to no avail it just seemed to have made it worse. Please help.<br />
Did you replace the gear or the shift dog <br /> classic symtom of worn dog.If it has gone on too long then you may have to do dog and gear.Dog is meant to wear not gear.
