The Tecnoseal 01143 series consists of sacrificial trim tab anodes designed for Yamaha 150–225 HP outboard motors, corresponding to Yamaha OEM part number 6J9-45371-00. Each anode features a circular base with an integrated angled vertical fin, an extended horizontal section and a central threaded mounting arrangement, helping protect submerged metallic lower-unit components against galvanic corrosion. The anode measures 87 mm in overall height (h) and 100 mm in circular base diameter (Ø), with an M10 × 1.25 mounting thread (m). Two material versions are available: zinc (Tecnoseal 01143, 520 g) and magnesium (Tecnoseal 01143MG, 130 g). Both versions share identical dimensions and mounting geometry for compatible Yamaha 150–225 HP outboard applications.

Tecnoseal 6J9-45371-00 Yamaha 150–225 HP Outboard Trim Tab Anode Ø100 mm

The Tecnoseal 01143 series consists of sacrificial trim tab anodes designed for Yamaha 150–225 HP outboard motors. Corresponding to Yamaha OEM part number 6J9-45371-00, these replacement anodes help protect submerged metallic components of compatible Yamaha outboard lower units against galvanic corrosion.

Each anode features a circular base with an integrated angled vertical fin and an extended horizontal section. The fin rises above the circular base to form the trim tab profile, while the central threaded mounting arrangement provides attachment to the corresponding lower-unit assembly. The zinc or magnesium body acts as a sacrificial material, gradually corroding during service to help reduce galvanic corrosion of surrounding protected metallic components.

The anode measures 87 mm (3.43 in) in overall height (h) and 100 mm (3.94 in) in circular base diameter (Ø). The mounting thread (m) is M10 × 1.25. These dimensions and the mounting geometry are common to both available material versions.

Two material versions are available. The zinc version, Tecnoseal 01143, weighs 0.52 kg (1.15 lbs). The magnesium version, Tecnoseal 01143MG, weighs 0.13 kg (0.29 lbs). Both versions share the same physical configuration, allowing the appropriate sacrificial anode material to be selected according to the vessel's operating water conditions.

This trim tab anode is identified for Yamaha 150–225 HP outboard applications. Before replacement, the OEM reference, vertical fin profile, circular base diameter and mounting thread should be checked against the existing component.
