Cavalier 32 Prop Anode

[Cavalier 32]

Hi All,

A surveyor has suggested that I should have an anode near my bronze prop. As far as I know, my girl has never had one fitted and I can't recall seeing any on other Cav 32's.

My girl is circa 1984 and has an enclosed prop set up very close to the rudder leading edge.

If a YES, what is the typical set up as far as wiring and connecting through the hull etc.

Cheers, Keith

If your shaft is solid coupled to the g box the engine anode will take care of the bronze prop,if it isn’t broken don’t fix it ,there is always enough to do on any boat,anodes only work if directly coupled to the underwater units to be protected.⛵️⚓️

No reason not to install a shaft anode forward of the prop and no wiring of any kind is needed (or possible.) You should know however that your engine anode is not going to protect your prop, nor is it designed to. Do you know how much exposed shaft exists between the prop and the cutless bearing?

The prop shaft is enclosed almost to the boss of the prop, no room for a shaft anode.

Not even 3/4"-1"?

my boat is the same ... no room on the shaft for any anode.

I have an anode bolted to the hull with a wire inside connecting to the shaft via a brush.

It would be nice if there were a way to fit an anode onto the prop so that it isn't reliant on the shaft brush.

What's wrong with a standard prop nut anode?

It's never been suggested as an option before ... do you think there's enough room for one? Would I need to disconnect the hull zinc, or would both be ok?

I presume they come with a standard thread? How does the split-pin that stops the nut backing off get past the fitting and go through the shaft?

sorry to OP for hijacking thread.

You would eliminate the existing nut and install the cone nut which has slots to allow for the installation of a cotter pin. The anode goes over it.

Thanks fstbttms , I'll look into it at the next haulout.

A diver could do it tomorrow.
