Tecnoseal Bruntons Autoprop H5 Zinc Propeller Anode

Tecnoseal AUTOH5 Bruntons Autoprop H5 Zinc Propeller Anode

The Tecnoseal AUTOH5 is a zinc sacrificial propeller anode designed for Bruntons Autoprop H5 feathering propellers. It provides a replaceable corrosion protection component for the propeller assembly, helping protect electrically connected underwater metallic parts against galvanic corrosion.

The anode has a compact, dome-shaped body with three integrated mounting lugs and fastening holes. Its geometry is designed for installation on the corresponding Autoprop H5 propeller assembly. The manufacturer's technical drawing specifies an overall height of 32 mm (1.26 in), an external dimension (a) of 55 mm (2.17 in) and a mounting dimension (i) of 41 mm (1.61 in). The anode incorporates a 34 mm diameter (Ø), a 27 mm internal diameter (Ø1) and 7 mm mounting holes (Ø2).

Manufactured from zinc, the Tecnoseal AUTOH5 weighs 0.17 kg (0.37 lbs). Its sacrificial construction allows the anode material to be consumed preferentially, reducing galvanic corrosion of compatible underwater propeller components.

Technical Specifications

Design and Mounting Configuration

The Tecnoseal AUTOH5 features a rounded, dome-shaped external profile with three mounting lugs distributed around the base. Each lug incorporates a fastening hole, allowing the anode to be secured to the corresponding Bruntons Autoprop H5 propeller assembly.

The mounting geometry is defined by a 41 mm dimension (i), 7 mm fastening holes (Ø2), a 34 mm diameter (Ø) and a 27 mm internal diameter (Ø1). The body has an overall height of 32 mm, with additional dimensions a = 55 mm and b = 21 mm.

Before ordering, compare these dimensions and the three-hole mounting arrangement with the existing anode. Confirm that the original propeller assembly corresponds to the appropriate Bruntons Autoprop configuration.

Compatibility

The manufacturer's catalogue identifies this anode for the Autoprop H5 series. The supplied product information also lists H-5BB and APS Saildrive propellers; compatibility with these additional configurations should be verified against the existing anode and propeller documentation before ordering.

Corrosion Protection and Maintenance

Manufactured from zinc, the Tecnoseal AUTOH5 functions as a sacrificial corrosion protection component. The zinc is designed to corrode preferentially, helping protect electrically connected underwater metallic components of the propeller assembly against galvanic corrosion.

Inspect the anode regularly for material consumption and replace it when significantly depleted. During installation, ensure suitable electrical contact between the anode and the propeller component requiring protection.
