Martyr Anodes Yamaha Skeg Anode Aluminum

Martyr Anodes Yamaha aluminum skeg anodes are sacrificial anodes for Yamaha outboard lower units. They protect the engine's metal parts from galvanic corrosion. Each anode corrodes in place of the lower unit, and it replaces the original skeg anode once that one has worn away.

Key Features:

• Cadmium-free aluminum alloy: Aluminum anodes from Martyr's maker, CMP, contain no cadmium, a substance of environmental concern.
• Saltwater and brackish water protection: Aluminum protects better and lasts longer than zinc in saltwater. In brackish water it avoids the passivation problem that can make zinc stop working.
• Lighter than zinc: Aluminum anodes weigh less than zinc anodes.
• Military-spec alloys: Martyr anodes meet US Military specifications for their alloys, and in-house testing helps hold quality to those standards.
• Bolt-on installation: The anode is a straightforward replacement that bolts onto the skeg.

Replace your skeg anode when it has eroded significantly. This keeps the lower unit protected through the boating season.
