Tecnoseal N51-11325-01 Yamaha Hydra Drive Zinc Pencil Anode with Brass Plug Ø12 x 52 mm – 3/8" BSPT

The Tecnoseal 01160T is a zinc pencil anode supplied complete with a brass threaded plug for Yamaha Hydra Drive sterndrive systems. Corresponding to Yamaha OEM part number N51-11325-01, this assembly provides sacrificial corrosion protection for compatible internal water-contacting metallic components.

The anode consists of a cylindrical zinc element fitted to a brass plug with a hexagonal head and tapered gas thread. The zinc element serves as the sacrificial component, while the brass plug provides the threaded mounting connection. Both components are supplied together as a complete assembly.

During service, the zinc element corrodes preferentially, helping reduce galvanic corrosion of protected metallic components exposed to water. The pencil anode should be inspected periodically and replaced when necessary according to the Yamaha drive manufacturer's maintenance recommendations.

According to the Tecnoseal catalogue, the assembly measures 52 mm (2.05 in) in length (l), with a zinc element diameter (Ø) of 12 mm (0.47 in). The brass plug head dimension (c) is 19 mm (0.75 in). The threaded connection is specified as 3/8" Gas Conico, a tapered gas pipe thread. The complete assembly weighs 0.06 kg (0.13 lbs).

The Tecnoseal 01160T is supplied in a zinc-and-brass configuration. Before ordering, compare the dimensions, tapered thread and Yamaha OEM reference with the original anode assembly.
