Tecnoseal 15670000 GORI Zinc Collar Anode for 2-Blade Saildrive Propellers 13–18"

Tecnoseal 01023 GORI 15670000 Zinc Collar Anode for 2-Blade Saildrive Propellers 13–18"

The Tecnoseal 01023 is a zinc sacrificial collar anode designed for GORI 2-blade Saildrive propellers in the 13–18 inch size range. It corresponds to original GORI part number 15670000 and serves as a replacement corrosion protection component for compatible propeller assemblies.

The anode features a curved, split collar design with mounting holes positioned along its body. This configuration is intended for attachment around the corresponding mounting section of the GORI propeller assembly. Manufactured from zinc, the anode provides sacrificial corrosion protection for electrically connected underwater metallic components.

The manufacturer's technical drawing specifies a length (l) of 98 mm (3.86 in), a width (a) of 40 mm (1.57 in) and a mounting dimension (i) of 79 mm (3.11 in). The mounting arrangement includes dimensions Ø = 11 mm (0.43 in) and Ø1 = 6.50 mm (0.26 in). The anode weighs 0.58 kg (1.28 lbs).

Technical Specifications

Design and Mounting Configuration

The Tecnoseal 01023 features a curved collar-shaped body designed for installation on a compatible GORI Saildrive propeller assembly. The technical illustrations show the collar profile and mounting holes used to secure the anode in position.

The manufacturer's drawing identifies a length of 98 mm (l), a width of 40 mm (a) and a mounting dimension of 79 mm (i). Additional fastening dimensions are specified as Ø = 11 mm and Ø1 = 6.50 mm. These measurements describe the mounting geometry and should be compared with the original component before replacement.

The collar configuration differs from conventional cone-shaped propeller nut anodes. When selecting a replacement, verify the shape, mounting dimensions and fastening arrangement rather than relying solely on the propeller diameter.

Compatibility with GORI Propellers

The Tecnoseal 01023 is specified for GORI 2-blade propellers for Saildrive installations, covering the manufacturer's indicated propeller size range of 13–18 inches.

• Compatible Manufacturer: GORI
• Propeller Configuration: 2-blade
• Installation Type: Saildrive
• Propeller Size: 13–18 inches
• Original Replacement Reference: GORI 15670000

The 13–18 inch specification refers to the compatible propeller size range, not the shaft diameter or the physical diameter of the anode.

Galvanic Corrosion Protection

Manufactured from zinc, the Tecnoseal 01023 functions as a sacrificial anode within the compatible propeller's corrosion protection arrangement. When electrically connected to the metallic components requiring protection, the zinc corrodes preferentially, helping reduce galvanic corrosion of those components.

Zinc sacrificial anodes are commonly used in saltwater applications. The suitability of the material should be checked against the vessel's operating environment and the manufacturer's corrosion protection recommendations.

Inspection and Replacement

Inspect the collar anode periodically during propeller maintenance. Replace it when the sacrificial material becomes significantly consumed or when its condition no longer permits secure installation.

Before fitting the replacement, check the mounting surfaces and fastening arrangement. Ensure suitable electrical continuity between the anode and the metallic component requiring protection.
