Amazing how electrolysis will eat up a prop. It's always interesting to see bad cases.

This was on a timber vessel called Odyssey after , and I think I got the story right, spending a few weeks on display at the Sanctuary cove boat show.
Went to move her and no go.

So unrecognizable all I kept thinking was, “I KNOW that’s not cinnamon “. Ha ha

Or perhaps better put - that was the shaft key!

The power of electricity - low voltage galvanic action at one end and high voltage lightening at the other end.

And lovely lights, music recordings, movie displays, communications devices, etc in the middle.

Could you imagine life without being able to control (mostly) electricity?

Don't forget all the buried steel gas/water/oil pipelines. I have surveyed countless gas pipelines where the cathodic protection failed.
The interesting thing with the pitted pipe in the picture below is that depending on the engineers report we could do the repair with a carbon fibre/epoxy resin bandage.

It can do nice things to bronze skin fittings too.

Which is why I don 't bond them together or to the ships ac ground system.

This is the shaft on the same boat as the prop pictured above.
