I grazed a sand bar at idle yesterday with the prop. Pulled it into neutral, trimmed up and floated across it. When I put it back in gear there was 1 clank but boat was moving. Pulled into neutral and put back in gear again.. No clank.. Gave it throttle and it planned off fine . Went to our next stop.. Left later and planned fine. 3rd time I tried to plane off it would almost get on plain then rpms would go up like the drive was trimmed too high but it was all the way down. Still able to make it home and no slipping at idle to 3000 rpms. Its an Alpha drive.. Have not had time to remove the prop and hub yet. Any Ides.

Make aligned marks on the hub and prop then take it for a hard ride. Then check your marks and see if they are still aligned. If not time to take it to the shop for repair.

Changed hub and problem solved
