Shaft bearing question C&L 79í

I’m preparing for hull out soon. Planing to replace shaft seals and inspect cutlass ext. I’m wondering about what’s in the shaft bearing. 4 nuts holding it to the hull looks like it could use remove and clean up and caulk back on. Wondering if these typicly have a cutlass pressed into them or is the shaft just floating like a metal shaft log?

I’ve never replaced the shaft seals on this boat so kinda trying to prepare parts wise for hull out if I need to work on the shaft bearing. Any pointers much appreciated if the shaft bearing is something I should not mess with if it looks ok mechanically ext..

Thanks
CEC

So it’s a flange bearing right? Wondering if someone has a source? I see a lot that look similar but not identical. Seems like a part you can’t press a cutlass into you replace the whole flange bearing. Anyone done this type of shaft bearing before?

I could be way wrong but that looks almost like it was redone later than the original hull. The glass has a different meaning tint, etc. I think the bolt at the top is a keeper for a bearing but not certain of it. If it is a longer shaft to the transmission then itís possible someone added a supporting bearing. The shaft inside my boat is about 5í or more and Iíve been told it should be supported. It comes through cutlass bearing and then shaft log straight to the tail shaft of the tranny. The overall length is about 14í?? So a LOT of unsupported shaft. The shaft log goes to the typical fiberglass cone with the carrier for the packing gland. My boat is a Ď77 so itís possible they cut off the fiberglass and bolted in the bearing plate you see here.

Not sure what I am looking at. Shaft hardware looks much smaller than expected on a 79' boat.

If that is a typo, then it would be unusual to have a bearing in that shaft log. May not know for sure til you haul it. There will be a bearing right in front of the prop, but no other needed unless shaft is like over 8' long depending on dia and speed.

Sorry the boat is a 1979 it’s 37’ it does look like one side was reenforced but the other side looks original. Shafts are like 6’ I believe.
