These are mil-spec aluminum anodes for Flexofold 3-Blade and 4-Blade propellers (up to 23"). This anode also fits Flexofold 2-Blade "LA" type props (2016 and later).
Aluminum is regarded to be the best anode material choice for boats that see some amount of time in salt, brackish, and freshwater - where traditional zincs may not protect as well. These aluminum anodes can last up to 50% longer in saltwater, while still offering good protection.
Includes a stainless steel mounting screw with a pre-applied underwater thread locker compound.
Compatible with:
- Flexofold 3-Blade and 4-Blade props (up to 23"), as well as on Flexofold "LA-type" 2-Blade propellers (2016 and later).
