Tecnoseal Anode Kit w/Hardware - Mercury Bravo 1 - Magnesium

The Tecnoseal Anode Kit w/Hardware for Mercury Bravo 1 in magnesium is essential corrosion protection for anyone who operates a Mercury Bravo 1 drive in saltwater or brackish environments. This complete anode kit provides sacrificial protection by corroding preferentially in place of your aluminum and steel drive components, extending the life of your propulsion system and avoiding costly mid-season repairs.

Tecnoseal's magnesium anodes work through galvanic potential—magnesium is more electronegative than the metals in your Bravo 1 drive, so it sacrifices itself instead of allowing corrosion to attack the drive housing, shaft, and internal passages. The kit includes all necessary hardware for direct installation, ensuring proper electrical contact and maximum protection. Magnesium is particularly effective in saltwater applications, offering faster corrosion rates than zinc or aluminum alternatives when water conditions demand it.

Mercury Bravo 1 owners who operate in saltwater, tidal zones, or regions with mineral-rich water should inspect and replace anodes annually—or every 100–150 operating hours in heavy salt-water use. The compact kit weighs just 1.5 lbs and mounts directly to OEM attachment points, making it a convenient choice for boaters looking to protect their investment.
