Corrosion at the pivot pin (or anywhere else) is not an issue with Martec folding props. With the Eliptec (non-geared) line of props, the ears will splay after years of use and the holes will wear over time, causing the blades to be sloppy in the hub but the Martec can be reburbished by the factory and properly maintained, they provide many years of good service.
