Any thoughts on a very lightly scored driveshaft in a 1/2 inch section 6 inches above where lower unit bolts on? It's a 1981 probably, very inexpensive, everything else works well. I use it as a kicker; thought I might use it this season and see if it's any worse in the fall. The scored part runs through a sleeve bearing that's under water in operation.
Thanks ahead .
