Tecnoseal Max Prop 2-Blade Zinc Cone Propeller Anode Ø36 mm

Tecnoseal 00489 Max Prop 2-Blade Zinc Cone Propeller Anode Ø36 mm

The Tecnoseal 00489 is a zinc sacrificial cone-shaped propeller anode designed for compatible Max Prop 2-blade propeller assemblies. Its tapered construction and recessed mounting arrangement are intended to provide a replacement sacrificial anode for the corresponding propeller configuration.

The anode has a distinctive conical outer profile with a rounded base and a central internal mounting cavity. The manufacturer's illustrations show fastening holes integrated into the lower section of the body, allowing attachment to the corresponding Max Prop propeller component.

With an overall height of 51 mm (2.01 in), an outside base diameter of 36 mm (1.42 in) and an internal diameter of 27 mm (1.06 in), the Tecnoseal 00489 is designed for a specific mounting configuration. Its zinc construction provides sacrificial corrosion protection for electrically connected underwater metallic components of compatible marine propeller systems.

Technical Specifications

Max Prop Compatibility

The Tecnoseal 00489 is intended for Max Prop 2-blade propeller installations. The manufacturer identifies the compatible propeller configuration but does not specify an individual Max Prop model designation or propeller diameter range in the supplied chart.

Before ordering, verify the original anode dimensions and mounting arrangement against the manufacturer's technical drawing. Particular attention should be given to the 36 mm outside diameter, 27 mm internal diameter, 51 mm overall height and fastening hole positions.

Design and Mounting Configuration

The anode features a conical outer body with a recessed central mounting section. Its tapered shape extends from the circular base toward the pointed upper section, while the lower section incorporates the fastening arrangement shown in the technical drawing.

The overall height (h) is 51 mm, and the maximum outside diameter (Ø) is 36 mm. The central mounting diameter (Ø1) measures 27 mm, with an additional mounting dimension (a) of 9 mm and a fastening hole diameter (Ø2) of 4.5 mm.

These measurements define the replacement anode's mounting geometry and should be checked against the existing Max Prop component before installation.

Galvanic Corrosion Protection

Manufactured from zinc, the Tecnoseal 00489 acts as a sacrificial corrosion protection component. When electrically connected to the underwater metallic parts requiring protection, the zinc corrodes preferentially, helping reduce galvanic corrosion of the propeller assembly.

Zinc sacrificial anodes are commonly used in saltwater environments. Material suitability should be confirmed according to the vessel's operating conditions and the propeller manufacturer's recommendations.

Inspection and Replacement

Inspect the anode during routine propeller maintenance and replace it when the sacrificial material is significantly depleted, damaged or no longer securely attached.

Before installation, compare the replacement dimensions with the original anode, inspect the fastening points and ensure suitable electrical contact with the metallic component requiring protection.
