I just bought a 1966 33 hp evinrude ski-twin, runs beautiful but shifts in and out of gear super fast and gets worse with increased throttle. the lower unit was removed for water pump impeller replacement and the shift linkage was hooked back up correctly, I checked and double checked that. I know that the previous owner had the bottom end apart he said to replace a leaking gasket. I also put fresh lube in the lower unit and the drain screw has like a pin on the end? I had a really hard time getting the screw back in as the pin was hitting something in the gear case. I would appreciate any suggestions or advice before I tear it apart this weekend. thank you
