Tecnoseal 6BL-11325-00 Yamaha 25 HP Crankcase Cylinder Anode Ø13 x 25 mm

The Tecnoseal 01161 series consists of small sacrificial internal engine anodes designed for Yamaha 25 HP outboard motors. Corresponding to Yamaha OEM part number 6BL-11325-00, these replacement anodes help protect metallic components within the crankcase and cylinder assembly against corrosion.

Each anode features a straight cylindrical body with a central axial hole extending through its length. The simple cylindrical profile and through-hole arrangement correspond to the design illustrated in the Tecnoseal catalogue. Both material versions have identical physical dimensions and mounting geometry.

The anode functions as a sacrificial corrosion protection component. During service, its zinc or magnesium material corrodes preferentially, helping reduce galvanic corrosion of surrounding protected metallic engine components. Inspection and replacement should follow the Yamaha engine manufacturer's maintenance recommendations.

According to the Tecnoseal catalogue, the anode measures 25 mm (0.98 in) in height (h), with an outside diameter (Ø) of 13 mm (0.51 in) and a central hole diameter (Ø1) of 6 mm (0.24 in).

Two material versions are available. The zinc version, Tecnoseal 01161, weighs 0.02 kg (0.04 lbs), while the magnesium version, Tecnoseal 01161MG, weighs 0.005 kg (0.01 lbs). The appropriate material should be selected according to the Yamaha engine manufacturer's requirements and operating water conditions.
