The Tecnoseal 01148 series consists of small cylindrical sacrificial anodes designed for Yamaha 4–70 HP outboard engines, corresponding to Yamaha OEM part number 6G8-11325-00. Intended for internal crankcase and cylinder applications, each anode features a slightly tapered cylindrical body with an axial mounting hole, helping protect metallic engine components against corrosion. The anode measures 16 mm in height (h), 13 mm in maximum outside diameter (Ø), 12 mm in secondary outside diameter (Ø1) and 5.50 mm in through-hole diameter (Ø2). Three material versions are available: zinc (Tecnoseal 01148, 10 g), aluminium (Tecnoseal 01148AL, 6 g) and magnesium (Tecnoseal 01148MG, 4 g). All versions share identical dimensions and mounting geometry. The catalogue also lists references 00844, 01750 and 01408-2 as alternative anode references for this design.

Tecnoseal 6G8-11325-00 Yamaha 4–70 HP Outboard Crankcase Cylinder Anode

The Tecnoseal 01148 series consists of small cylindrical sacrificial anodes designed for Yamaha 4–70 HP outboard engines. Corresponding to Yamaha OEM part number 6G8-11325-00, these replacement anodes are intended for internal crankcase and cylinder applications, helping protect metallic engine components against corrosion.

Each anode features a compact, slightly tapered cylindrical body with an axial through-hole. The body has a wider outside diameter at one end and a slightly smaller outside diameter at the other, creating the profile shown in the Tecnoseal catalogue drawing. The central opening provides the fastening arrangement for installation in the corresponding Yamaha engine location.

The anode functions as a sacrificial corrosion protection component. During service, its zinc, aluminium or magnesium body gradually corrodes preferentially, helping reduce corrosion of surrounding protected metallic engine parts. These anodes are replaceable maintenance components and should be inspected according to the engine manufacturer's maintenance recommendations.

According to the Tecnoseal catalogue, the anode measures 16 mm (0.63 in) in height (h), 13 mm (0.51 in) in maximum outside diameter (Ø) and 12 mm (0.47 in) in secondary outside diameter (Ø1). The central through-hole diameter (Ø2) is 5.50 mm (0.22 in). These dimensions are identical for all three available material versions.

Three versions are available. The zinc version, Tecnoseal 01148, weighs 0.01 kg (0.02 lbs). The aluminium version, Tecnoseal 01148AL, weighs 0.006 kg (0.01 lbs), while the magnesium version, Tecnoseal 01148MG, weighs 0.004 kg (0.01 lbs). The appropriate sacrificial material should be selected according to the engine manufacturer's requirements and the vessel's operating water conditions.

The catalogue also identifies references 00844, 01750 and 01408-2 as alternative references for this anode design. These references can assist in identifying the correct replacement when comparing Tecnoseal catalogue listings and existing engine components.
