Choosing the right metal

Hope I can get some help here. I need to replace the attachment on my Pearson's swing keel. The old one has corroded to almost nothing. It may be nearly 50 years old. It looks like it is probably some kind of bronze. It's only about 1/8 inch thick at best and in some places is almost paper thin. The board weighs maybe 200 lbs.

I can get 220 bronze sheet cut to size and would only have to drill a couple of holes to make the replacement. Or I can get aluminum bronze in 1/4 inch bar stock that could work and I think is more corrosion resistant than the 220 in seawater.

If any of you guys can tell me which way to go, I will really appreciate it so I can get this repair done and get this boat back in the water.

I've tried to get some info from a thread in the Pearson forum, but maybe here will get more exposure.

Re: Choosing the right metal

Any chance of a picture or a drawing? not quite seeing what exactly you're needing to replace (but confess lack of familiarity with that boat/system)..

How's this. This is not mine, but just like it (except this one is in good shape).

Re: Choosing the right metal

I would go with 316 stainless, and bolts, the cable should be 316 SS and the swage should be zinc coated copper. At least that is what lasted 25+ years before I changed it out for new last year. My details can be found here

Re: Choosing the right metal

I'd use the most corrosion resistant bronze flat bar I could get. I prefer bronze to S/S underwater if I have the choice.

Frankly though, I don't think it much matters - I'm sure many boats have had fittings like that made from galvanized iron or steel.

Re: Choosing the right metal

Thanks Closecall.. that should be easy to fabricate once you choose your material!

Re: Choosing the right metal

Try drmarine.com for a replacement. Ask for Rudy.

You'll need VIN, year and model.

The cable is SS and if in contact with brass in salt water, the SS will win out as you can clearly see in my thread.

The problem here is abrasion in the cable tube. Why change something that is proven to work.

Edit: My bad, I thought you were suggesting Dyneema. I miss read that.

Re: Choosing the right metal

I believe I'll go with stainless. The rest of the system is stainless so that makes sense. Also stainless is more readily available. Thanks for the input.
