The CMT-PNDAF14 is a 7/8" aluminum propeller nut anode designed to protect propeller nuts, shafts, and surrounding running gear from galvanic corrosion. This compact anode replaces the standard prop nut or installs in conjunction with it, providing direct protection at one of the most corrosion-prone points on the drivetrain.
Manufactured from marine-grade aluminum alloy, it delivers long-lasting protection in saltwater and brackish environments, outperforming traditional zinc in most real-world conditions.
