Tecnoseal 67F-11325-00 Yamaha 80–300 HP Outboard Crankcase Cylinder Anode

Tecnoseal 67F-11325-00 Yamaha 80–300 HP Outboard Crankcase Cylinder Anode

The Tecnoseal 01146 series consists of sacrificial internal engine anodes designed for Yamaha 80–300 HP outboard motors. Corresponding to Yamaha OEM part number 67F-11325-00, these replacement anodes help protect metallic components within compatible Yamaha engine crankcase and cylinder assemblies against galvanic corrosion.

Each anode features a compact cylindrical body with a raised square-profile section at one end and an internal threaded mounting hole at the opposite end. The stepped cylindrical construction provides the sacrificial metal body, while the square-profile section forms part of the anode's installation geometry. This design differs from external trim tab, bracket and lower-unit anodes because it is intended for an internal engine application.

The sacrificial material gradually corrodes during service, helping reduce galvanic corrosion of protected metallic engine components. The anode is a replaceable maintenance component and should be inspected according to the engine manufacturer's maintenance requirements.

According to the Tecnoseal catalogue, the anode measures 32 mm (1.26 in) in overall length (l) and 23 mm (0.91 in) in cylindrical body diameter (Ø). Additional dimensions are 5 mm (0.20 in) for a, 17 mm (0.67 in) for b, 10 mm (0.39 in) for c and 15 mm (0.59 in) for h. The internal mounting thread (m) is M6. These measurements are common to all three available versions.

Three material options are available. The zinc version, Tecnoseal 01146, weighs 0.07 kg (0.15 lbs). The aluminium version, Tecnoseal 01146AL, weighs 0.027 kg (0.06 lbs), while the magnesium version, Tecnoseal 01146MG, weighs 0.02 kg (0.04 lbs). The material should be selected according to the operating environment and applicable Yamaha maintenance specifications.

The same anode design is also listed under Tecnoseal catalogue references 01914 and 00846. These additional references can assist in identifying the corresponding replacement component when comparing catalogue listings and existing engine anodes.
