Hi and Thanks for any help, Prior to changing the water pump I had the shifter in forward position. While reinstalling lower unit I had trouble getting it to mesh the last 2 inches. I put the shifter in neutral to see if that would help. It didn't. Turned flywheel while trying to install and it finally meshed. Ran motor and water coming out the tell tale. Shifted in forward and prop spinning. Shifted to reverse, prop spinning (did not notice prop rotation, duh). Put boat in water and had no reverse. Took lower unit back off and turned shift spline by hand (actually vice grips) and found neutral. Had shifter already in neutral and reinstalled. Ran motor and no forward or reverse. Took lower unit back off and recorded shaft rotation for different positions while turning splined connector by hand. Here's the sequence : At the ccw stop going cw it turned kind of hard and went into neutral. Still going cw it went into FWD. (turning prop by hand to verify position). Turned very freely then hit resistance that would kind of spring back a bit. Turned ccw it went freely and was still in FWD. Turned more and was in neutral. Then it hit resistance like before. Turned back cw and it went into FWD. Turned freely then went into both FWD and REV by turning prop. Continued cw and hit neutral. More turn and FWD. Then resistance. Be wildered and tired. Thanks for help!

You just don't have the shift rod in the right spot.
Drop it down and try again.
I/8th a turn can make the difference between F/R

Thanks Jerry, As I understand what you are saying is that the actual shifter is not quite in neutral? On the other end in the lower unit with it taken off , does the spline connector when turned by hand have stops going CW and counter CCW? And I need to have it in neutral (free turning prop) between FWD and REV? The only REV I ever get is a position that will turn the shaft either way when turning the prop. Seems like REV is never by itself, when the prop only will turn CW?

The shift shaft in the drive, turn it 1/8" at a time and spin the prop shaft.
It will eventually hit the right spot.

Sorry for being an idiot, but I don't understand what you are saying? I can turn the drive shaft by hand and it makes the prop turn whether I'm in neutral, fwd or rev. The shift shaft connector I turn with channel locks, but when I had it in neutral and reconnected to the motor and started the motor the prop didn't turn in either forward or reverse.

The pic shows the top of the shift shaft.
Turn that 1/8th a turn until it hits the right spot.
You can be as much as 180d out and the prop turns.
Spin the prop not the drive shaft and try to find the right spot.

The 'right spot' I assume is neutral? I had it in neutral after removing the lower unit the 2nd time, but after reinstalling and running the motor it wouldn't turn the prop when I shifted into fwd or rev?? Thanks again for your patience!
