Had charger on my boat the other day and something shorted. It got hot enough that the plastic cam that connects to the shift rod melted enough that it broke when I tried to shift it. I replaced the shift cam and pin latch but the motor will not shift out of forward. When I move the remote shift back to neutral it gets really tight and won’t go into neutral or reverse. With some effort I can pull it far enough toward neutral that I can crank it but it will not shift completely into neutral. I recently had some work done on lower unit and noticed that they had left the washer off of the top of the shift rod that engages and releases the motor lock. I took the lower unit off and replaced the washer and put everything back together but it will still not shift back into neutral or reverse. It runs fine in forward. Any help would be much appreciated. Thanks.
