I"ve got a 1998 Mariner 15hp 4 stroke. The pull start is getting locked up. The shifter on the side of the motor seems to get stuck when this happens. If you set there and play with both after awhile it will pull and work. Doesn't happen every time I try to start it, but enough that I'm afraid it is going to strand me sometime. Also it seems hard to pull compared to other motors, I talk to older guys all the time and when they go to leave it seems like they reach back with 2 fingers and pull theirs to start. It takes all I've got to pull it normally. Any ideas would be great. Thanks
