    Lower unit concerns

    Struck bottom last fall. We hit an unmarked rock at the mouth of a harbor. I have since learned that the harbors private owner has not maintained the entrance for years including not marking this obstacle. My B3 props are both being rebuilt, but the lower unit is making noises when put in either forward or reverse. Nothing huge, but something is wrong. We put on maybe 50 hours after the incident and the noise seemed to get a little louder. I will have it torn down and repaired this spring. Any idea what I damaged and what the repair will involve? Did I wreck a bearing, the u-joint or some gears?

    Since the noise is not present the upper half is ok with the unknown of the cone clutch however it’s most likely in the lower end gears or bent prop shaft.

      Agree with Mike. The prop shaft is likely bent causing a slight vibration and bearing failure. I’d check the shafts for runout

          Have you considered making an insurance claim if you have insurance?
