Gori 20x13x3LH Folding Propeller – 3-Blade, Ø20", Pitch 13", Left-Hand, for 35 mm ISO Shaft

Gori 20x13x3LH Folding Propeller – 3-Blade, Ø20", Pitch 13", Left-Hand, for 35 mm ISO Shaft

The Gori 20x13x3LH is a high-performance 3-blade folding propeller engineered for 35 mm ISO shaft systems. Introduced in 1994 and recognized with both the DAME and HISWA Awards, this model remains at the forefront of marine propulsion innovation.

Key Features

• Size: Ø20", Pitch 13"
• Rotation: Left-hand (LH), 3-blade folding design
• Shaft Compatibility: 35 mm ISO shaft
• Engine Range: 7 kW (10 hp) to 221 kW (300 hp) and above
• Overdrive Function: Allows pitch adjustment under power for optimized motor performance
• Efficiency: +15% in forward and reverse compared to traditional folding/rotary blade propellers
• Low Drag: Compact profile when folded reduces sailing resistance
• Debris Resistant: Shape prevents entanglement with seaweed and plastic
• Reduced Vibration: Curved blade design minimizes noise and vibration

Overdrive Function

The unique Overdrive function enables the helmsman to adjust pitch and blade profile while under way, using the boat’s single lever control—without hydraulics or complex mechanics. This results in reduced fuel consumption, lower RPMs, less engine noise, and enhanced cruising efficiency in calm conditions or when motoring under sail.

Performance Under Sail

When folded, the propeller has an extremely low drag profile, significantly improving boat speed under sail. Independent tests confirm the efficiency gain, contributing to better racing performance and fuel economy.

Performance Under Engine

Thanks to the optimized curvature and blade rotation, the propeller delivers +15% higher thrust in both forward and reverse compared to other folding and rotary propellers. This improves maneuverability and reliability across a wide range of operating conditions.

With its proven engineering, premium materials, and over 25 years of field success, the Gori 20x13x3LH folding propeller offers unmatched value in both cruising and performance sailing applications.
