Description
Product Overview
The captainmarine Marine Anode Kit is engineered to defend your outboard engine against corrosive damage. Constructed from high‑grade zinc, the anode acts as a sacrificial metal, drawing electrical currents that would otherwise degrade the gearbox housing. Dimensions are compact at 4 x 3 x 3 inches and the kit weighs just 2 pounds, making handling straightforward. It replaces OEM part numbers 822777Q1, 97-822777T1, 46399A1, among others, ensuring a perfect fit for a wide range of Mercury, Mariner, and MerCruiser models released from 1995 onward.
Usage
Designed for marine environments, this anode kit is ideal for recreational boaters, commercial operators, and maintenance technicians who need dependable corrosion control. Install the anode on the trimming tab of the gearbox housing; the metal will quickly form an oxide layer, protecting critical components during regular sailing, fishing trips, or offshore work. Regular inspection and replacement keep the hull and engine in optimal condition, extending service life and reducing costly repairs.
