Re: [Amel Yacht Owners] Modified SM Prop Shaft Seal Bush
I believe that you are over complicating the issue. As far as I remember the seals were from a local seal shop in Larnaca. I have no idea of the hardness but I can check when I get there next week as I bought more than I have used.
As far as the stainless is concerned, just plain old 316 is all I know. As Heinrich is no longer with us, I cannot find out, but maybe someone can test the bush which I still have.
The thing is Bill is that you are advocating people remain with a
situation that we all know lets us down unexpectedly and often at
an awkward time. You say you worry about protecting an expensive
system yet you encourage owners to suffer sea water mixing with
the lubricating oil. When this happens not everyone is in a
position to haul out immediately. More damage may be done if this
The benefits of what I have proven are:
The bush does not wear at anything like the rate of a bronze one.
As a result, it is now highly unlikely that the oil will be
contaminated between say three year haul outs.
There is no electrolysis problem with stainless on stainless. at
least not if lubricated with an anti corrosion grease such as
The fact that Amel are experimenting with a stainless surface
indicates that this is the way to go. I am so glad that Amel have
latched onto the idea, as they have with my idea of using sealed
bearings in the bow thruster. Maybe they will look at a stainless
sleeve on the bow thruster shaft too. It works!
You can protect the past all you want Bill, but my goal is to reduce nuisance servicing to the minimum so that I can enjoy sailing the boat.
Sometimes it pays to think outside the box.
Not sure about the mileage accolade. 48,273 as I speak almost all single handed. But then on an Amel that's easy!
Kindest regards to you and Judy
