I pulled the carrier bearing and everything is good on the inside, just the bearing around the shaft is shot. I don't want another case (unless I get another as a backup) because anything new I will have to get modified again for the nose cone pickup and torque tab.

Make sure you get a seal kit before re-assembling. Water in that area is usually due to a bad seal in the water pump base.

yep, thanks for the reminder. I went ahead and ordered a whole new seal kit, water pump kit, and bearings obviously.

Can someone help me identify what is holding back the drive shaft? I have the pinion nut removed. The prop shaft is still in there - unsure if I really need to remove that though it would make reinstalling the pinion nut much easier.

I got the remains of the bearing removed, but the shaft won't pull out. I can't tell if there is still part of the bear race down there or if that is the lubrication sleeve?

beat it with a hammer.....not for the faint of heart.......Sideways slammmm....

That pinion has been there a while and usually they don't come off without a little hand to hand combat.

What should have been a relatively easy fix today is turning into a pain, as it always goes. I got the new tapered roller bearing pressed onto the shaft. As I am sliding the shaft back in the install the pinion, of course it hit the lower pinion bearing and knocked all the rollers out. Now I did order a new pinion roller bearing just in case, but my existing was still good so I was going to just use it... until I knocked everything out.

It looks like that bearing presses out through bottom and comes out the prop hole. In some videos, I have seen where the bearings come up through the shaft column. I don't think this one comes up because there appears to be a lip preventing that. I also can't find any online manuals and a factory one plus special tools at this point is going to be more expensive than just taking it to a shop.

I am also thinking about packing that bearing race and the rollers themselves with bearing grease or petroleum jelly and refitting them back in, though that is probably a very tedious task.

It's really not that hard to do, just look at the rollers and see if you can see a pattern on the rollers and bearing race to put them back in the original orientation (top and bottom). It's not mandatory, but if you can see the pattern, the better. This way, they roll in the original direction.

Thanks everyone, again. Got the LU reassembled and got it out today and it runs better than ever. Still the RPMs are a little slow to climb when hammering it from a hole shot but once it finally spins up it is up on plane real quick and runs great. Still not sure why the slight hesitation from the start but still feels like a brand new boat compared to the last couple years.
