This is also a must. Glad you brought that up.

Have you had any trouble with corrosion at the solder?

I think the key has to do with what you said about it being sealed. Tin coated wire seals the copper, The solder seals the wire and fills the air spare around the strands, the wire jacket also seal the wire and the heat shrink with glue seals the air from all under it. Keeps the salt air and moisture out of it. There could be some slight reactions between the dissimilar metals but it will be minor in comparison to salt air or moisture.

Agree completely on the tinned wire but I’m constantly amazed how many bilge pump‘s and other marine equipment comes with just standard copper wire you would think that they would know better of course cost is always the factor

Didn’t notice whether the wire was tinned but just replaced a still working Rule bilge pump which was perhaps 25+ years old. I also have a much newer backup.
