I just replaced the water pump on my F225TXRA and it wouldn't shift into forward or reverse after I finished putting the lower unit back on. I figured the shift lever moved or was not lined up properly so I dropped the lower unit back down and carefully lined everything up and slowly reattached. I check to make sure I was able to shift into forward and reverse before I tightened everything up, but when I was finished it would not shift into forward or reverse. So I loosened the 9 bolts that hold the lower unit on just a few turns, and found that I am able to shift forward and reverse - I tighten the bolts up and I can not. What am I missing please.
