My question is for a late 80's V6 150 - i was going along at a high rpm and the motor seemed too wind out. I stopped the the motor and it would start fine but not go into gear. I took the lower unit off and it seems to be fine, i can shirt it manually when its off the boat. I put the lower unit back on and it does shift into gear fine with the motor not running - if i try to shift when the motor is running it doesnt shift into gear -
