Tecnoseal Max Prop Saildrive Zinc Collar Anode – Internal Ø63 mm

Tecnoseal 00485-1 Max Prop Saildrive Zinc Collar Anode – Internal Ø63 mm

The Tecnoseal 00485-1 is a zinc sacrificial collar anode designed for compatible Max Prop Saildrive propeller assemblies. This ring-shaped replacement component is intended to provide galvanic corrosion protection for electrically connected underwater metallic parts of the propeller system.

The anode features a circular collar body with a central opening and a split mounting arrangement. Its external profile includes a chamfered outer surface and lateral fastening points, allowing the component to be secured around the corresponding mounting section of a compatible Max Prop assembly.

The anode measures 93 mm (3.66 in) in outside diameter, 63 mm (2.48 in) in internal diameter and 20 mm (0.79 in) in overall height. The fastening arrangement includes a hole diameter of 5.5 mm (0.22 in). Its weight is 0.42 kg (0.93 lbs).

Technical Specifications

Design and Mounting Configuration

The Tecnoseal 00485-1 features a circular, ring-shaped construction with a central opening and fastening points positioned around the outer body. The manufacturer's technical drawing shows a split collar profile with a chamfered outer surface, designed for installation around the corresponding section of a compatible Max Prop Saildrive assembly.

Its 63 mm internal diameter is the primary dimension for identifying the required collar size. The outside diameter of 93 mm and height of 20 mm define the overall external dimensions of the anode. The manufacturer also specifies a 5.5 mm fastening hole diameter.

Before installation, compare the existing anode's dimensions and fastening arrangement with the manufacturer's technical drawing to confirm compatibility.

Max Prop Saildrive Compatibility

The Tecnoseal 00485-1 is intended for compatible Max Prop Saildrive propeller systems requiring a zinc collar anode with a 63 mm internal opening.

The manufacturer's supplied chart identifies the Saildrive application but does not provide a specific Max Prop model number or propeller diameter range. Compatibility should therefore be confirmed using the existing anode dimensions and mounting configuration.

Galvanic Corrosion Protection

Manufactured from zinc, this collar anode functions as a replaceable sacrificial corrosion protection component. When electrically connected to the underwater metallic parts requiring protection, 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 collar anode during routine propeller maintenance and replace it when the sacrificial material is significantly depleted, damaged or no longer securely mounted.

Before fitting the replacement, check the mounting surfaces, fastening points and internal diameter. Ensure suitable electrical contact between the anode and the metallic component requiring protection.
