SEACHOICE Sacrificial Anode Kit for Yamaha 200–250 hp Outboards, Aluminum, One Size, Cadmium-Free

Seachoice's aluminum anode kit for Yamaha 200–250 hp outboards provides targeted, cadmium-free sacrificial protection for the gimbal housing and ventilation-plate skeg to reduce galvanic corrosion in salt and brackish water.

If you own a Yamaha 200–250 hp outboard, this two-piece Seachoice kit delivers OEM-style protection for vulnerable lower-unit and gimbal areas using aluminum anodes that meet Mil-Spec A-24779(SH). The kit replaces the original block anode at the gimbal housing plus the skeg-style anode for the ventilation plate, offering an environmentally friendlier alternative to cadmium-based fittings. It's engineered specifically for the listed Yamaha models and intended for marine environments where stray-current and electrochemical wear are concerns.

How does this kit protect my Yamaha outboard from corrosion?

The aluminum anodes act as sacrificial metal, corroding preferentially to steel and aluminum components on your outboard. By creating a controlled galvanic cell, the anodes divert electrochemical attack away from critical parts, preserving the motor's structural elements and fasteners.

• Includes a block anode sized for the gimbal housing and a skeg anode for the ventilation plate.
• Aluminum composition designed for salt and brackish water environments.
• Cadmium-free construction reduces environmental toxicity and disposal concerns.

Which Yamaha engines will these anodes fit and what comes in the kit?

This kit is manufactured to fit a broad range of Yamaha 200–250 hp 4-stroke models and specific model suffixes listed by Yamaha. Seachoice supplies the two replacement parts needed for those lower-unit areas so you can match OEM fitment quickly.

• Compatible with Yamaha F225, F250, F300 4-stroke and multiple 200–250hp model codes (see product fit list).
• Kit contains 1 gimbal housing block anode and 1 ventilation-plate skeg anode.
• Manufacturer part number: 50-95231 for straightforward cross-referencing.

How do I install and maintain these anodes for best performance?

Installation is straightforward for anyone familiar with lower-unit servicing: remove the old anodes, inspect mounting hardware and mating surfaces, then torque the new anodes to manufacturer recommendations. Periodic inspection and replacement when the anode has worn substantially will keep galvanic protection effective.

• Inspect anodes each season or after extended saltwater use; replace when more than 50% consumed.
• Clean mating surfaces and use proper torque for secure electrical contact.
• Keep fasteners clean and free of paint or corrosion to maintain the electrical path.

Why choose cadmium-free aluminum anodes from Seachoice?

Seachoice aluminum anodes are formulated to balance protection and environmental responsibility. Cadmium-free alloys reduce toxic metal release while still providing robust sacrificial action suited to marine conditions.

• Conforms to Mil-Spec A-24779(SH) for material quality and performance.
• Lower environmental impact compared with cadmium-based alternatives.
• Designed and distributed by a marine-focused brand run by boaters for boaters.

Who is this for? Boat owners with Yamaha 200–250 hp outboard engines who need reliable, environmentally conscious sacrificial protection for the gimbal housing and ventilation plate. This kit is ideal for anglers, watersports enthusiasts, and recreational boaters operating in salt or brackish water who want direct OEM-style replacement anodes that are simple to install and maintain.
