Sierra 18-6035 Zinc Anode, Replaces Yamaha 6J9-45371-01-00, for 150-200 HP Outboards

The Sierra 18-6035 is a zinc anode built to protect Yamaha outboard motors from galvanic corrosion. As a sacrificial anode, it corrodes in place of the more expensive metal components on the outboard, giving critical engine parts a longer service life in fresh, brackish, or salt water. It is designed for Yamaha outboards rated 150-200 HP and directly replaces the Yamaha OEM anode numbered 6J9-45371-01-00.

Constructed from zinc, the 18-6035 is engineered to meet or exceed the quality of the original equipment part it replaces, giving boat owners a reliable, drop-in corrosion-protection component. Regular anode replacement is a routine part of outboard maintenance, and keeping a compliant anode installed helps prevent premature pitting and deterioration of the powerhead, lower unit, and other submerged metal parts. At a compact size and light weight, the 18-6035 is easy to keep on hand as a spare for scheduled maintenance intervals.
