SEACHOICE Aluminum Anode Kit for Volvo Penta SX/DP‑SM Outdrives — Cadmium‑Free, Direct‑Fit with Hardware

Seachoice's aluminum anode kit protects Volvo/OMC SX outdrive components from galvanic corrosion using cadmium-free, Mil-Spec A-24779(SH) compliant parts.

This kit supplies targeted sacrificial anodes engineered for Volvo Penta SX and DP-SM drives, intended for salt and brackish water environments. Designed as direct-fit replacements, the components slow electrochemical wear on critical outdrive areas while eliminating cadmium from the alloy. The package includes a ventilation-plate top anode, a gimbal-housing block anode, and a full set of 18 stainless steel fasteners, giving you the hardware required for a complete installation.

Which Volvo drives does this anode kit fit?

The kit is manufactured to fit Volvo Penta SX and DP-SM drives, including SX dual-propeller models and OMC SX configurations. It is sized to match factory mounting points and wear areas on those drives, making it a straightforward OEM-style replacement.

• Compatible with Volvo Penta SX and DP-SM outdrives
• Works with SX dual propeller setups
• Designed to match original mounting locations
• Manufacturer part number 50-95341 for reference

How do these anodes reduce corrosion on my outdrive?

These aluminum anodes act sacrificially, corroding in place of steel and other metal parts to prevent pitting and galvanic damage. By providing an electrically preferred path for electrochemical reaction, they preserve housings, gimbals, and ventilation plate areas that would otherwise degrade faster in marine conditions.

• Aluminum alloy sacrifices before steel components
• Protects gimbal housing and ventilation plate surfaces
• Suitable for saltwater and brackish environments
• Cadmium-free composition minimizes environmental impact

What comes in the Seachoice anode kit and what standards do the parts meet?

The kit contains one ventilation-plate top anode, one block anode sized for the gimbal housing, and eighteen 8/304 stainless steel screws to complete the installation. All aluminum parts conform to Mil-Spec A-24779(SH), and the fasteners are corrosion-resistant grade 304 stainless steel.

• 1 top anode for the ventilation plate
• 1 block anode for the gimbal housing
• 18 stainless steel 8/304 screws included
• Parts meet Mil-Spec A-24779(SH); cadmium-free alloy

How do I install and maintain these anodes?

Installation follows the original anode mounting points: remove the old anodes, clean mating surfaces, fit the replacement anodes, and torque the supplied stainless screws. Regularly inspect anodes for heavy erosion; replace when more than 50% consumed or if attachment points are compromised.

• Remove old anodes and clean contact surfaces before fitting
• Use supplied 8/304 stainless screws to secure anodes
• Inspect periodically; replace if significantly worn
• Follow torque recommendations and safety procedures

Who is this for: This Seachoice anode kit is aimed at boat owners, marine technicians, and service yards maintaining Volvo/OMC SX and DP-SM outdrives who want an OEM-style, environmentally conscious replacement. It suits vessels operating in salt or brackish water that require reliable sacrificial protection and easy-to-install components—especially useful for routine outdrive service intervals and seasonal preparations.
