The Tecnoseal 01131 series consists of sacrificial block anodes designed for the engine mounting brackets of Yamaha 40–50 HP outboard motors, corresponding to OEM part numbers 63D-45251-01 and 63D-45251-00. Each anode features a contoured, channel-shaped body with two recessed mounting holes and reinforcing ribs, helping protect metallic outboard bracket components against galvanic corrosion. The anode measures 85 mm in length, 62 mm in width and 32 mm in height, with 46 mm mounting-hole spacing (i) and 7 mm fastening-hole diameter (Ø). Three material versions are available: zinc (01131, 570 g), aluminium (01131AL, 220 g) and magnesium (01131MG, 140 g). All versions share identical dimensions and mounting geometry. The same anode design is also listed under Tecnoseal catalogue reference 01651.

Tecnoseal 63D-45251-01 / 63D-45251-00 Yamaha 40–50 HP Outboard Bracket Anode

The Tecnoseal 01131 series consists of sacrificial block anodes designed for the mounting brackets of Yamaha 40–50 HP outboard motors. Corresponding to Yamaha OEM part numbers 63D-45251-01 and 63D-45251-00, these replacement anodes help protect metallic outboard bracket components against galvanic corrosion.

Each anode features a contoured block with a channel-shaped profile designed to follow the corresponding mounting area of compatible Yamaha outboard brackets. The body incorporates two recessed mounting holes, curved supporting surfaces and raised reinforcing ribs. This configuration allows the anode to fit around the bracket mounting area while providing a replaceable sacrificial metal surface.

The anode measures 85 mm (3.35 in) in overall length, 62 mm (2.44 in) in width and 32 mm (1.26 in) in height. The mounting-hole spacing (i) measures 46 mm (1.81 in), while the fastening-hole diameter (Ø) is 7 mm (0.28 in). The shaped profile and mounting dimensions should be compared with the original component before replacement.

Three material versions are available with identical dimensions and mounting geometry. The zinc version, Tecnoseal 01131, weighs 0.57 kg (1.26 lbs). The aluminium version, Tecnoseal 01131AL, weighs 0.22 kg (0.49 lbs), while the magnesium version, Tecnoseal 01131MG, weighs 0.14 kg (0.31 lbs). These alternatives allow the appropriate sacrificial anode material to be selected according to the vessel's operating water conditions.

The same anode design is also listed under Tecnoseal catalogue reference 01651, providing an additional reference for identifying the corresponding replacement component.
