Hub anodes

[PabloPicasso]

I have a two bladed folding prop on my sail drive. The prop hub has three anodes that struggle to last six months. The lifting or slipping is costly and or time consuming. Is it possible to double up the anodes somehow? Or put on bigger ones?

No. You are stuck with what you have. The prop is isolated from everything else and the anodes are to deal with galvanic action between the stainless pins and bronze prop. No way of connecting additional anodes. Nice little earner for the manufacturers, but not all brands of folding prop have them - or if they do, consume anodes so quickly.
