Sierra 18-6132M Anode Kit for Yamaha 200-250 HP Outboard Motors

The Sierra 18-6132M is a complete magnesium anode kit designed as a direct-fit replacement for Yamaha outboard motors in the 200–250 HP range. Anodes are a critical component of any marine engine's corrosion protection system, sacrificing themselves to protect vital metal components on the lower unit, trim tabs, and engine housings from electrolytic and galvanic corrosion in saltwater, brackish, and freshwater environments.

Key Features:

• Magnesium alloy construction — ideal for freshwater use where galvanic protection is essential
• Direct OEM replacement fit for Yamaha 200–250 HP outboard engines
• Includes all necessary anodes to complete a full service replacement
• Manufactured to Sierra's OEM-equivalent quality standards for reliable, long-lasting protection
• Helps protect lower unit housings, trim tabs, and other submerged metal components
• Easy installation with no modification required

Sierra International is a trusted name in aftermarket marine parts, producing components that meet or exceed original equipment manufacturer specifications. Regular anode replacement is a key part of outboard motor maintenance and helps extend the service life of your Yamaha outboard investment.
