I have a 1984 Force 85hp outboard that seems like it might be popping out of gear when it is under a load after an impeller change. At low rpms it does fine, if you give it a lot of throttle or increase to a higher rpm, it will make a noise and jerk like it is popping out of gear if I back off it does okay. I thought that it was a coincidence and I had nicked a rock with my prop so I thought I had a issue with a spun prop. I sent the prop out and had it repaired and the repairer said the hub was okay. There is a shifting shaft that is threaded that I had to remove and replace while installing the impeller. I was thinking that it may be out of adjustment. just wanted to see if anyone knew about this issue or had run into this problem before I tear into the motor again.
Thanks for you input. Tom
