Not possible. You've got to pull out the rudder stock from below to change the lower bearings. The stern has to have quite a bit of clearance under it as the rudder + stock are quite tall.

I did mine years ago and FP sent me a PDF file showing the rudder / stock assembly.

Re: Rudder bearings

Thanks for your reply Muskova. Can you tell me why its not possible in say 4 metres of water with a diver underneath. Are the bearings pressed on the shaft as well as into the housing or are they threaded.
Would it be possible to get away with some of the newer bearing material like vesconite turned down to suit bottom and top bearings. I've emailed FP so hopefully they will send drawings to me. Further to that what is the quickest access to the stern area to change the steering cables. Appreciate your help

Re: Rudder Bearings

Hi Blaze,

1. Don't know if you could do it in the water. If it's clear water give it a try. I think the bearings just pressed on, but it was 6 years ago so I'm not 100%. They're nylon so you could turn them out of something else.
2. The steering gear area is accessed through the aft cabin bulkheads. We have a Maesto layout so it's different on both sides - the port side access is through a bulkhead. The starboard master cabin is via the storage locker behind the berth. It's tight but doable.

Re: Rudder Bearings

If you are just changing the inner bearing you may be able to do it with the boat in the water.
However the outers are usually corroded and need replacing too which will require the boat to be out of the water.
You can save money by buying the bearings from the manufacturer instead of FP.
However there is a common belief that the originals are made of inferior material so you would be better off getting some made from a higher grade material.
Good luck.
