Tecnoseal 01139 Yamaha 6T5-45251-00 Sterndrive Zinc Anode Plate (1989–1990)

The Tecnoseal 01139 is a zinc sacrificial anode plate designed for Yamaha sterndrive systems from 1989 to 1990. Corresponding to Yamaha OEM part number 6T5-45251-00, this replacement anode helps protect submerged metallic components of compatible Yamaha sterndrives against galvanic corrosion.

The anode features a distinctive U-shaped, open-centre construction with two elongated arms connected by a transverse section. Multiple mounting holes are positioned along the arms, allowing the plate to be secured to the corresponding sterndrive mounting area. The open central profile and fastening arrangement distinguish this component from conventional rectangular and circular marine anodes.

Manufactured from zinc, the Tecnoseal 01139 acts as a sacrificial corrosion protection component. During operation, the zinc is gradually consumed, helping reduce galvanic corrosion of surrounding protected metallic parts. The anode is intended for periodic inspection and replacement as part of sterndrive maintenance.

According to the Tecnoseal catalogue, the anode has an overall length dimension (l) of 108 mm (4.25 in) and an overall dimension (a) of 122 mm (4.80 in). The additional dimension (b) measures 62 mm (2.44 in), while the plate thickness (h) is 10 mm (0.39 in). The mounting dimensions (i) and (i1) are 76 mm (2.99 in) and 93 mm (3.66 in), respectively. The fastening-hole diameter (Ø) is 7 mm (0.28 in).

The anode weighs 0.35 kg (0.77 lbs). Before installation, the existing Yamaha sterndrive anode should be checked against the original part number, U-shaped body profile, overall dimensions and mounting-hole arrangement to confirm compatibility.
