Yamaha anode 664-45371-01

An anode provides extra protection against corrosion. The anode will corrode sooner, thereby protecting the engine. All Yamaha anodes are made of a zinc and aluminium alloy and are therefore suitable for all types of water. We recommend assessing whether the anode needs to be replaced based on a visual inspection. The external anode at the tailpiece and/or bracket is easy to replace, but the internal anode requires specialist knowledge.

This anode is suitable for the following engines:
2-stroke: 20D, 25J, 25N, 30D and 40V
4-stroke: F20G and F25G
