Bite the bullet and get a PSS seal HG. You'll have a dry bilge, no adjusting the cutlass bearing to one drip a minute, etc.
I fitted one and so glad I did.

I Negotiate the PSS seal kit as a deal for the slipping sail drive a engine reconditioner from Canada is a PSS seal agent that bought the sail drive for repairng



both parties are extremely happy with there trading

I don't really understand this because the pss seal does not replace the cutlass bearing

Hi HG

From what he had written I thought he was confusing a cutlass bearing with a stuffing box

It is not about the "brand", it is about the material it is made of.

Being as how you want to go traditional, lignum vitae would be fitting, but IF you can find it, the cost might be more than you have spent on the yacht so far.

If you are going to replace your existing I suggest getting the old one out first and see how much damage the extraction causes to where it was bonded.

Once you have cleaned up the damage and made the aperture into an as near as possible a cylindrical hole, get somebody to turn up a bush from Delrin or similar. It needs to measure 5 thou less on the O.D. than the hole it is going into so that it can be glued in with epoxy glue. The I.D. needs to have grooves in it to allow water lubrication and maybe 3 to 5 thou clearance on the shaft.

Before extracting the old stern bearing you should fit up the engine on the old shaft and bearing as accurately as possible and give it a run to make sure bearing and shaft replacement are really necessary. If it is necessary, use the engine position as a datum point to which the new shaft and bearing will be fitted to.

Ask yourself the question and answer it honestly "Do I really need to replace the stern bearing??"

The H28 club owns a jig Ill see If I'm allowed to borrow it Cisco.
There's two materials Duramax nitrile(rubber) and Tufnol I have heard the nitrile doesn't like sand around bass straight
Mine appears to be the later Tufnol.

Hi HG

The Walker Sailmasters appear to have the bearing in a external bolt on housing (the photo below is not mine but another one from down here)

Are the Walker H28's the same or are they internal in the hull

The Nitrile might be too hard on the SS. This place is just up the road from me. www.cammthane.com.au/

Mate has one of there cutlass bearings in his fishing boat, 2 inch shaft. I think it is vesconite, cost about $27. Probably similar companies where you live.

You're right Don - I was confusing the cutlass bearing with the stuffing box. I realized that right after I posted my reply, but couldn't retract it.
From now on I'll try not to shoot from the hip....:)

Im guessing the Cammthane is polyurethane. Good low friction, high wear resistance material. The concept of the cutlass bearing is a fluid bearing, the shaft essentially riding on a film of water. Some even have a hexagonal shape internally.

I found some Vesconite marine bushes 1" Id X 1.25 " OD X 4 inches long $22.00 each
I'm not to sure how long I need but would like to do the job at the weekend . They do offer longer pieces so Ill either buy two 4 inch longs or a 12 inch length if I can.
And cut off what I don't need
