The Tecnoseal 01151 series consists of cylindrical sacrificial pencil anodes designed for internal crankcase and cylinder applications on Yamaha 9.9–300 HP outboard engines, corresponding to Yamaha OEM part number 66M-11325-00. Each anode features a stepped cylindrical body with an axial M5 internal mounting thread, helping protect metallic engine components against corrosion. The anode measures 31 mm in overall length (l) and 10 mm in outside diameter (Ø), with a 15 mm stepped-section length (l1). Three material versions are available: zinc (Tecnoseal 01151, 10 g), aluminium (Tecnoseal 01151AL, 4 g) and magnesium (Tecnoseal 01151MG, 3 g). All three versions share identical dimensions and mounting geometry. The same anode design is also listed under Tecnoseal catalogue reference 01752.

Tecnoseal 66M-11325-00 Yamaha 9.9–300 HP Outboard Crankcase Cylinder Pencil Anode Ø10 mm

The Tecnoseal 01151 series consists of cylindrical sacrificial pencil anodes designed for Yamaha 9.9–300 HP outboard engines. Corresponding to Yamaha OEM part number 66M-11325-00, these replacement anodes are intended for internal crankcase and cylinder applications, helping protect metallic engine components against corrosion.

Each anode features a compact stepped cylindrical body with a larger-diameter section at one end and a narrower cylindrical section at the other. An axial M5 internal threaded hole provides the mounting arrangement. This stepped profile distinguishes the component from straight cylindrical pencil anodes and should be checked when identifying the correct replacement.

The zinc, aluminium or magnesium body serves as a sacrificial corrosion protection element. During service, the anode material gradually corrodes preferentially, helping reduce galvanic corrosion of surrounding protected metallic engine components. Regular inspection and replacement should follow the Yamaha engine manufacturer's maintenance recommendations.

According to the Tecnoseal catalogue, the anode measures 31 mm (1.22 in) in overall length (l) and 10 mm (0.39 in) in outside diameter (Ø). The stepped-section length (l1) is 15 mm (0.59 in), and the internal mounting thread (m) is M5. These dimensions and mounting characteristics are identical for all available versions.

Three material versions are available. The zinc version, Tecnoseal 01151, weighs 0.01 kg (0.02 lbs). The aluminium version, Tecnoseal 01151AL, weighs 0.004 kg (0.01 lbs), while the magnesium version, Tecnoseal 01151MG, weighs 0.003 kg (0.01 lbs). The appropriate material should be selected according to the engine manufacturer's specifications and operating water conditions.

The catalogue also lists Tecnoseal reference 01752 as an alternative reference for this anode design. This additional reference can help identify the corresponding replacement when comparing catalogue listings or existing Yamaha engine components.
