Tecnoseal 689-11325-00 Yamaha 25–30 HP Crankcase Cylinder Zinc Anode (1984–1997)
The Tecnoseal 01121 is a compact zinc sacrificial anode designed for the crankcase cylinder of Yamaha 25–30 HP outboard motors manufactured between 1984 and 1997. Corresponding to Yamaha OEM part number 689-11325-00, this replacement anode helps protect metallic engine components exposed to water against galvanic corrosion by providing a replaceable sacrificial zinc surface.
The anode features a small, contoured plate with a raised rectangular section, a shaped end and a recessed mounting hole. Its compact profile is intended for the corresponding anode mounting position on compatible Yamaha engine assemblies. The zinc material is gradually consumed during service, helping reduce corrosion of the surrounding protected metallic components.
The anode measures 28 mm (1.10 in) in length, 15 mm (0.59 in) in width and 9 mm (0.35 in) in height. The central mounting through-hole has a diameter of 7 mm (0.28 in). It weighs 0.02 kg (20 g) and is identified as Tecnoseal part number 01121. The same anode design is also listed in the Tecnoseal catalogue under reference 01760.
