I have a similar problem.... I took the boat for the first time. 70 hp johnson and got it started no problmem everyone ready to go. Engaged the throttle and tried going forward with no luck ...how embarassing :-/ when I bought it the seller said to get it checked out he moved it but had to play with some bolt or something and barely got it to go into gear... It seems to be locked could this be the throttle cable or the actual throttle mechanism. Thanks so much!
