Tecnoseal 63P-11325-21-00 Yamaha Crankcase Cylinder Zinc Anode 150 HP
The Tecnoseal 01165 is a zinc sacrificial internal engine anode designed for Yamaha 150 HP outboard motors. Corresponding to Yamaha OEM part number 63P-11325-21-00, this replacement anode helps protect metallic components within the engine crankcase and cylinder assembly against galvanic corrosion.
The anode features a compact cylindrical, washer-shaped body with a countersunk central opening. Its circular profile and tapered internal recess correspond to the design illustrated in the Tecnoseal catalogue. This configuration is intended for the specified Yamaha internal engine anode installation.
The zinc material acts as a sacrificial corrosion protection component. During service, the anode corrodes preferentially, helping reduce galvanic corrosion of surrounding protected metallic engine components. Inspection and replacement should follow the Yamaha engine manufacturer's maintenance recommendations.
According to the Tecnoseal catalogue, the anode measures 6 mm (0.24 in) in height (h), with an outside diameter (Ø) of 12 mm (0.47 in) and a central opening diameter (Ø1) of 6 mm (0.24 in). The zinc anode weighs 0.005 kg (0.01 lbs).
