Tecnoseal 825171 Yamaha 30–50 HP Outboard Bar Anode

Tecnoseal 825171 Yamaha 30–50 HP Outboard Bar Anode

The Tecnoseal 01126 series consists of sacrificial bar anodes designed for Yamaha 30–50 HP outboard motors. Corresponding to original part number 825171, these replacement anodes help protect metallic outboard components against galvanic corrosion by providing a replaceable sacrificial metal surface.

Each anode features a straight, elongated rectangular body with an oblong mounting slot at one end and a circular fastening hole at the opposite end. The mounting arrangement is designed for compatible Yamaha outboard installations, while the sacrificial anode material helps reduce corrosion of surrounding metallic components exposed to water.

The bar measures 194 mm (7.64 in) in overall length, 19 mm (0.75 in) in width and 12 mm (0.47 in) in height. The mounting-hole spacing (i) measures 166 mm (6.54 in), with a 7 mm (0.28 in) fastening-hole diameter and an additional 14 mm (0.55 in) mounting dimension (b). These measurements correspond to the technical drawing supplied in the Tecnoseal catalogue.

Two material versions are available. The zinc version, Tecnoseal 01126, weighs 0.29 kg (0.64 lbs), while the magnesium version, Tecnoseal 01126MG, weighs 0.07 kg (0.15 lbs). Both versions share identical dimensions and mounting geometry, allowing the appropriate sacrificial material to be selected according to the vessel's operating water conditions. The same anode design is also listed under Tecnoseal catalogue reference 00822.
