I just bought this boat and sometimes when I pull it from fwd to nutral it remains in gear and sometimes when I put it in reverse it makes the nasty sound of the drive dog not engaging with the reverse gear. is there an adjustment that I can do that will enable it to disengage from fwd better and go into rev. better. or is my reverse rounded off. I have searched and found nothing that fits this description. I have disasembled and replaced gears in the lower units of johnson and mercury's hopefully I do not have to do this again. one other thing if I really quickly jam it into reverse it will engage and work until I put it back down to where idle should be in reverse then it will disengage and make the awful racket. I do not have a book yet but plan to buy one shortly I have to order it. its a 1987 pro v 150 thanks
