Happy New Year Listmates,

Looking for some insight on replacing the cutalss bearing for the propshaft. I noticied some uneveness in the prop wash at the end of the season. Thought it was barnacle buildup but now that the boat is hauled, its clear the bearing needs to be replaced. 

Bene spareparts has a standard version for $55 but I have seen some threads on alternates. 

Seems fairly straight forward, remove shaft, remove old bearing and replace. Any tips would be appreciated. 

Thanks and have a wonderful, safe and healthy 2021!

Best,

Jon

I just did mine on my 331, didn’t need to remove shaft.  Cleaned shaft up, removed propeller, and used dish soap/pliers to wiggle off the old cutlass.  I then used a really fine sandpaper and gently smoothed shaft before some more dish soap and slipping the bearing in place.

Cant tell from your photos if it’s the same flanged design.  There may also be a couple of screws you’ll need to remove and replace.

I had my shaft disconnected mainly because I also replaced my dripless too.  Could have done cutlass alone without.

You probably don't need to remove the shaft, with a long needle nose pliers spray some lubricant and gently pull it out as you turn it. Make sure first to remove the two screws on each side and the prop. If you remove the shaft you will end up having to lineup the engine and that is not an easy task.

A Beneteau bearing in the uk is approx £14 call it $20. Easy job prop off securing screws out bearing pushed or pulled out. Long nose pliers work for us. 👍🇺🇸

Thanks all. 

I do have to remove the shaft to replace the specialty set screws on the damper plate for the transmission gearbox. One broke off in the fly wheel last year when replacing the plate.  I also have a Max prop so not sure I want to take that off the shaft, that seems more  complicated but I may be wrong.

If you leave prop on you may not get it past your rudder.

No need to remove the shaft. Just the prop. Two set screws on the side. A little good luck and old one will come out. 

You only thing you need is a good prop puller.

Still No need to remove the shaft. It will slide back to enough to remove the transmission flex plate etc. 

I changed the transmission and flex plate in the water in the Bahamas. It took about an hour to remove the retransmission

Thanks Fletch. The max prop is a bit complicated but not insurmountable. Agreed taking it off is the easier method. 

Does one have to replace both the metal and rubber part of the bearing or just the rubber bearing? 

Thanks!

Fletch,

This is the cutlass bearing from Beneteau Spare parts, others I have seen also have a bronze sleeve.

From what I can tell and from the diagram, this is the only piece (106) - I do not visibly see a brass sleeve between housing and rubber bearing. Is this correct? The prop shaft o/d is 30mm.

Thanks much,

Jon

I actually just was sent a replacement bearing that had a brass sleeve.  I returned it on advice from this group, but also that I was worried I would have a tougher time getting it out next time.  Just replaced with the all rubber version.

If you already have the brass sleeve, I’m curious how difficult it will be to pull out?

I have no idea how you can change the cutlass bearing without removing the propeller unless you were to remove the rudder. That’s a bigger job.  

I am keening interested in your proposed method on leaving the prop in place.

If it’s a one piece rubber Beneteau bearing then it’s just one bit to replace. If however it’s a standard cutless bearing brass and rubber they are bounded together and are as one.

You seem to be making this more complicated than it is.



I would send the brass cutless back and get the proper one. I have only seen the brass cutless on boats with struts.

The only problem I see is how to get the bearing out since the flange piece is gone. Maybe some one else can chime in.

Good luck

Thanks much for the info. I did google the removal etc. I’m just ultra cautious on new to me jobs. If I can tackle a timing belt I’m sure I can remove a prop.

I’m looking at the bearing and there is almost no movement in the shaft but the bearing has degraded enough to warrant a replacement. The fit is so precise that extracting it with the shaft in place will be a challenge I’m sure.

If there is no movement in the shaft with respect to the bearing .. why are you replacing it?

If it's just the rubber one try screwing in a couple of drywall into the rubber to help extract.
My boat had a phenolic /rubber no way it would come ,I had to remove shaft and used a socket that fit the I'd of tube and joining extensions I was able to pound it out.Since having it out I replaced the Volvo dripless ,added an R&D coupling,aligned engine and the glassed the tube where comes out of hull.
This is a weak point in all Beneteaus 
They seal the tube hull joint with 5200 many have this seal fail and or fail to maintain,water then runs up the tube and into the boat .
My tube is glass later moorings had them change it to SS, too many towing dinghies had two rope wrap and crack tube
And to remove shaft I had to drop the rudder

They come out easier than you think. 

A couple of small picks or awls with a formed 90 degree sharp end at the tip

Hook each side 180 degrees apart and gently work it out. 

Be sure you have the two plastic screws out.

Hi Jon I've done the cutlass bearing twice on my B50 it also has a Maxprop. My original had a fiber outer to the bearing I had to remove the shaft the prop and drop the rudder. Each time I tackle this job the old bearing just wont come out without cutting through it to break the seal. There are details on line for the Maxprop removal just make a note of all the settings and make sure you mark up the outer casing before removal. My prop comes off the shaft easy each time. Toughest job for me is removing the drive coupling from the top end of the shaft, It's always very tight and difficult to get at. I used the brass/rubber type bearing this last time, I'll see if that makes the job easier next time.
