[QUOTE="JMichael, post: 358644, member: 7544"] A couple of years ago I acquired an 8 horse Merc with a bent prop shaft. It also had water in the oil when I drained the lower unit. According to my dial indicator, the shaft was 8° out from straight. The manual says that 6° is the limit before replacing. After pricing new and used replacement shafts, I knew it was more than I was willing to invest in the little motor. I decided to try and straighten it myself. I was able to straighten it out enough to get it back to within 1° of straight. I reinstalled the shaft and figured I'd replace the seals if my repair job worked OK. As it turned out, the bent shaft must have been distorting the seal enough that it was causing it to leak, because it never leaked again and the motor ran great after the repair. I know the motor and shaft you are dealing with are larger, but if you have the equipment, I'd say there's a good chance you can straighten it and get it back to within tolerance limits. [/QUOTE]
