Tecnoseal Trim Plate Anode - Zinc Flat Mercury Alpha f/Engines

The Tecnoseal Trim Plate Anode – Zinc Flat Mercury Alpha for Engines is an essential sacrificial protection component designed to protect your outboard motor from galvanic corrosion in saltwater and brackish environments. This anode is crucial for maintaining the integrity of aluminum trim plates and lower unit components on Mercury outboards, preventing costly repairs due to corrosion.

Constructed from a specially formulated zinc, this anode is engineered to corrode preferentially to aluminum and steel components, providing effective cathodic protection. The flat trim plate design allows for direct mounting to the Mercury Alpha lower unit, placing the anode in the primary corrosion zone where saltwater circulation is most aggressive. This ensures reliable protection against corrosive elements in marine environments.

Boaters operating in saltwater, brackish rivers, or coastal bays will benefit from the Tecnoseal Trim Plate Anode, which should be replaced every 1–2 seasons based on water salinity. This compact anode, weighing 0.7 lbs, provides sufficient mass for multi-season protection without adding unnecessary weight or drag to your transom.
