SEACHOICE Aluminum Anode Kit for Yamaha 150–200 HP, Cadmium‑Free — Gimbal Housing & Ventilation Plate Protection

This compact replacement kit includes the critical sacrificial anodes needed to guard the gimbal housing and ventilation plate on compatible Yamaha outboards. Engineered to meet Mil‑Spec A‑24779(SH) and built without cadmium, the SEACHOICE kit offers a durable, environmentally conscious option for keeping your lower unit parts protected from galvanic corrosion while on salt or brackish water.

Which Yamaha engines will this anode kit fit?

The kit is designed for Yamaha outboards in the 150–200 HP range across both 2‑stroke and 4‑stroke families, including specific models listed by Yamaha. It covers many common engine variants from 1988 onward, so it suits both newer and older boats when you need OEM-style protection.

• Fits F150, VF150 (4‑Stroke) and F175, F200 series (4‑Stroke)
• Includes compatibility for 150/175/200 HP 2‑Stroke models from 1988–1990 and newer
• Also fits select 225-series variants like 225ETLD, 225TLR, 225TXR
• Manufacturer part number: 50‑95211 for easy cross-reference

How do these aluminum anodes protect my outboard in saltwater conditions?

Sacrificial anodes corrode preferentially to the metal parts of your outboard, absorbing galvanic current generated by dissimilar metals and electrochemical activity. These aluminum pieces are positioned to shield the gimbal housing and ventilation plate, limiting pitting and deterioration of the attached components.

• Block anode protects the gimbal housing from stray currents and electrolytic attack
• Skeg anode shields the ventilation plate and reduces propeller-area corrosion
• Aluminum composition offers balance of life and conductivity in seawater
• Cadmium-free design minimizes environmental impact during use and disposal

What’s included and how simple is installation?

The kit includes two purpose‑shaped anodes sized for straightforward replacement of original parts. Installation is a basic mechanical task for anyone comfortable with lower unit maintenance; most owners can swap these anodes during routine service or while the motor is on a stand.

• Kit contents: 1 block anode for the gimbal housing, 1 skeg anode for ventilation plate
• Direct-fit parts for listed Yamaha models — no reshaping required
• Hand tools typically sufficient; torque and fastener recommendations follow Yamaha service guidance
• Replacing worn anodes regularly extends the life of polarized components

Who is this for: This SEACHOICE anode kit is intended for boat owners, mechanics, and marinas that service Yamaha outboards in salt or brackish environments and want a cadmium‑free, Mil‑Spec conforming replacement. It suits recreational anglers, workboat operators, and anyone maintaining 150–200 HP Yamaha engines who prefers responsible, proven sacrificial protection without compromising fit or performance.
