PROP ZINC SOLUTION

By Tom Assenmacher (1975 yawl SHEARWATER)

When we bought our boat in 1982, it had no zinc as it had always been in Lake Ontario. I took a bronze prop nut, welded a short piece of 1" bronze tubing to the nut, and placed a regular 1" donut zinc on the aft end of the prop.

Probably cuts down a bit on the prop efficiency, but not enough to notice.
