Tecnoseal 01134SX Trim Tab Anode Zinc Yamaha SX Outboard Skeg Sacrificial Zinc

The Tecnoseal 01134SX is a zinc trim tab anode (sacrificial skeg anode) engineered specifically for Yamaha SX outboard engines. Manufactured by Tecnoseal, a leader in marine corrosion protection, this replacement anode delivers dual functionality: it acts as a sacrificial corrosion barrier and assists with hydrodynamic steering performance.

As a sacrificial anode, this zinc component preferentially corrodes in place of more expensive and harder-to-replace engine parts. It protects against the three primary types of marine corrosion — simple electrochemical corrosion, galvanic corrosion, and electrolytic/stray current corrosion — making it especially important for saltwater use. The anode should be inspected regularly and replaced once it has corroded to approximately half its original size.

In addition to corrosion protection, the trim tab anode counteracts propeller torque and reduces prop-walk — a propeller's tendency to pull the boat to one side — helping maintain directional balance and more neutral steering. Replacement is a straightforward maintenance task that can typically be completed in minutes.
