My neighbor and I swapped out a newer (1996)50hp Merc for a 1986 90hp Merc. I kept the same controls and everything works except for one little problem.In neutral the prop spins, and although I haven't decided to reach out and touch it, it spins with enough authority to assume that it is slightly in gear. All the local boatyards are too busy to get me in for about two weeks, and this is almost prime blackfishing season. Any help would be appreciated.
