The Tecnoseal 01136 series consists of sacrificial trim tab anodes designed for Yamaha 9.9–15 HP outboard motors, corresponding to Yamaha OEM part number 66M-45371-00. Each anode features a tall, angled vertical fin attached to a compact mounting base with two fastening holes, helping protect submerged metallic outboard components against galvanic corrosion. The anode measures 53 mm in length (l), 38 mm in width (a) and 62 mm in overall height (h), with 7 mm mounting-hole diameter (Ø). Two material versions are available: zinc (Tecnoseal 01136, 90 g) and magnesium (Tecnoseal 01136MG, 20 g). Both versions share identical dimensions and mounting geometry, allowing selection of the appropriate sacrificial material according to operating water conditions.

Tecnoseal 66M-45371-00 Yamaha 9.9–15 HP Outboard Trim Tab Anode

The Tecnoseal 01136 series consists of sacrificial trim tab anodes designed for Yamaha 9.9–15 HP outboard motors. Corresponding to Yamaha OEM part number 66M-45371-00, these replacement anodes help protect submerged metallic components of compatible Yamaha outboard lower units against galvanic corrosion.

Each anode features a tall, angled vertical fin rising from a compact mounting base. Unlike conventional round trim tab anodes, this model has a distinctive fin profile and a base with two fastening holes. The sacrificial metal body provides corrosion protection for surrounding metallic components by gradually corroding during service.

The anode measures 53 mm (2.09 in) in length (l), 38 mm (1.50 in) in width (a) and 62 mm (2.44 in) in overall height (h). The mounting-hole diameter (Ø) is 7 mm (0.28 in). These dimensions correspond to the technical drawing in the Tecnoseal catalogue and are identical for both available material versions.

Two material versions are available. The zinc version, Tecnoseal 01136, weighs 0.09 kg (0.20 lbs), while the magnesium version, Tecnoseal 01136MG, weighs 0.02 kg (0.04 lbs). Both versions share the same shape, dimensions and mounting configuration, allowing the appropriate sacrificial anode material to be selected according to the vessel's operating water conditions.

The Tecnoseal 01136 series is intended for Yamaha 9.9–15 HP outboard applications. Before replacing the existing trim tab, the OEM reference, mounting-hole arrangement and vertical fin profile should be compared with the original component.
