Just replaced forward and pinion gear in a 1980 Chrysler 115hp. Took out this weekend and when put in forward gear the boat will jerk as if the gear is popping in and out. This will happen every 4 seconds. It would idle in forward if you have at low throttle. The Clutch dog did not seem to be worn at all so that was not replaced. It will go in reverse and move without problem. Any suggestions on what it can be. The motor has ran wonderful until the piviot screw was removed. That was the reason for replaceing the gears. When we took the boat out of the water we put the shifter in forward gear and we can spin the prop by and and the shift rod will move up and down with a pop.
