The CMT-852835Z is a zinc bar anode designed for Volvo Penta 290 sterndrive (outdrive) systems, providing essential galvanic corrosion protection to the drive housing and underwater components.
Mounted directly to the outdrive, this anode sacrifices itself to protect critical aluminum components from corrosion caused by electrolysis in saltwater environments. Zinc is the traditional and effective choice for full saltwater applications, offering reliable protection for sterndrives operating in consistent salinity.

Parts Desk Insight
Zinc is still the best choice for pure saltwater use, especially on older Volvo drives like the 290. If the boat is used in mixed water, consider switching to aluminum for longer life and better performance.
