Tecnoseal 01138 / Yamaha 6UA-45251-00 Hydra Sterndrive Zinc Plate Anode

The Tecnoseal 01138 is a zinc sacrificial plate anode designed for Yamaha Hydra sterndrive systems. Corresponding to Yamaha OEM part number 6UA-45251-00, this replacement anode helps protect submerged metallic sterndrive components against galvanic corrosion.

The anode features a rectangular plate-shaped body with two raised cylindrical mounting bosses on its underside. Two recessed fastening holes pass through the mounting sections, providing attachment points for the corresponding Yamaha Hydra drive assembly. The contoured underside includes supporting surfaces around the cylindrical sections, while the flat rectangular plate forms the main sacrificial body.

Manufactured from zinc, the anode serves as a replaceable sacrificial component. During service, the zinc gradually corrodes preferentially, helping reduce galvanic corrosion of surrounding protected metallic sterndrive parts.

The Tecnoseal 01138 measures 99 mm (3.90 in) in overall length (l), 45 mm (1.77 in) in width (a) and 32 mm (1.26 in) in overall height (h). The centre-to-centre mounting-hole spacing (i) is 27 mm (1.06 in). Each mounting recess has a diameter (Ø) of 20 mm (0.79 in), while the fastening-hole diameter (Ø1) is 9 mm (0.35 in).

The zinc anode weighs 0.28 kg (0.62 lbs). Its two-point fastening arrangement and raised cylindrical mounting profile are intended for compatible Yamaha Hydra sterndrive installations. Before ordering, the original part number, mounting-hole spacing and body dimensions should be compared with the existing anode.
