ok 2007 Optimax 115hp and I went to do impeller change tried 7 times and finally decided to put in gear to turn prop get shaft aligned. I know better now to just grab flywheel and turn clockwise. By myself no help. Now the question is why can I not find neutral, reverse seems stuck in fwd. Gear case is sitting on ground and trying to get neutral and put shifter neutral try button lower unit back on. Ok history of this motor bought at auction never started it! Is there an issue with lower unit or am I just not working shifter shaft correct?
