This is super helpful as I'm on the hard now trying to get old JP3 pieces out of 2018 L40... the biggest challenge is getting the spare parts - right now I'm told the spares are weeks or months out so no Sawsall action here. There were 3 Leopards in a row here (Tortola BVI) doing this repair - all less than 5 year old boats! For those who haven't delved in to this yet, those Delrin bearings swell up in water and then seize against the rudder - in other words kind of inevitable that they will seize... Fantastic step by step, very much appreciated! thank you!
I think it is really important to stick to the 3 year bearing replacement schedule JP3 recommends to avoid issues. Most of us just ignore the bearings until there is a noticeable problem, and then it's too late and the housing are trashed too. Also, some materials will swell, but JP3 claims their material doesn't; so, I know people have had issues when asking a machinist to make them new bearings out of Delrin as it's not the right material to use for the job.
Good video!!! What i did is i had the ring that holds the rudder with the screw going through it, made 2-3 times higher ( there is enough space!!), because it breaks right where the screw goes through the plastic. So this is what i would suggest to do...
Incredibly helpful. Thanks so much! Should you bond that new housing to a sacrificial anode somewhere? My bearing and housing are stuffed because of electrolysis and pitting.
I wander if you make the same mistake again, applying aluminium housing again. Jefa is having the same parts in polyurethane. So, no corrosion, which means no oxide between the bearings, less friction and long lasting. Apart from this, you do not need to apply anode wiring to keep the aluminium sleeve in condition. I want to mention one useful hint here,- be aware what kind of antifoul you are applying as corrosion is progressive with antifouls that contain copper. That way you have a combination of stainless still, and copper that is etching aluminium by electrolysis.

Great video thanks for taking the time to show other people. Very Very informative
Thanks for the video. Great job explaining the process.
I’m just beginning this project in my L39. Great help. Thanks.
Glad it could help you! Good luck!
Excellent video - very helpful. And kudos to you - nice job
Great explanation. I did both my fittings in October while on the hard.
Well done video! Wish I had this when I owned an L46!

Where did you get the fiberglass tubes made. We're in Florida Fort Lauderdale area
Incredibly helpful. Thanks so much!

Not sure... JP3 does not mention doing this in any of their literature but you could certainly ask them!
