The Tecnoseal 01147 series consists of small sacrificial internal engine anodes designed for Yamaha 40–90 HP outboard motors, corresponding to Yamaha OEM part number 688-11325-00. Each anode features a compact, shaped metal body with a U-shaped recess, an angled mounting section and a 5 mm fastening hole, intended to protect metallic components in the engine crankcase and cylinder assembly against corrosion. The anode measures 23 mm in overall length (l), 20 mm in height (h), with an additional dimension (l1) of 7 mm and a 5 mm mounting-hole diameter (Ø). Two material versions are available: zinc (Tecnoseal 01147, 10 g) and magnesium (Tecnoseal 01147MG, 3 g). Both versions share the same dimensions and mounting geometry. The same anode design is also listed under Tecnoseal catalogue reference 01759.

Tecnoseal 688-11325-00 Yamaha 40–90 HP Outboard Crankcase Cylinder Anode

The Tecnoseal 01147 series consists of small sacrificial internal engine anodes designed for Yamaha 40–90 HP outboard motors. Corresponding to Yamaha OEM part number 688-11325-00, these replacement anodes are intended for crankcase and cylinder applications, helping protect metallic engine components against corrosion.

Each anode features a compact, shaped metal body with an open U-shaped recess and an angled mounting section. The body incorporates a 5 mm fastening hole, while the surrounding metal profile provides the sacrificial material. The unusual shape and mounting arrangement distinguish this component from conventional cylindrical pencil anodes and external lower-unit anodes.

The anode is designed to act as a replaceable sacrificial corrosion protection component. During service, the zinc or magnesium material gradually corrodes preferentially, helping reduce corrosion of surrounding protected metallic engine parts.

According to the Tecnoseal catalogue, the anode measures 23 mm (0.91 in) in overall length (l) and 20 mm (0.79 in) in height (h). The additional dimension (l1) is 7 mm (0.28 in), and the mounting-hole diameter (Ø) is 5 mm (0.20 in). Both material versions have the same dimensions and mounting configuration.

Two versions are available. The zinc version, Tecnoseal 01147, weighs 0.01 kg (0.02 lbs). The magnesium version, Tecnoseal 01147MG, weighs 0.003 kg (0.01 lbs). The appropriate material should be selected according to the engine manufacturer's maintenance requirements and operating water conditions.

The same anode design is also listed under Tecnoseal catalogue reference 01759. This additional reference may assist in identifying the corresponding replacement when comparing manufacturer catalogue listings.
