Gori 16.5x13x3RHS Folding Propeller – 3-Blade, Ø16.5", Pitch 13", Right-Hand, for Sail Drive

The Gori Propeller 16.5x13x3RHS is a high-efficiency 3-blade folding propeller developed for sail drive systems. Since its introduction in 1994, it has received international recognition, including the DAME and HISWA Awards, for its innovative design and outstanding marine performance.

Key Features

• 3-blade folding design with right-hand rotation
• Diameter: Ø16.5", Pitch: 13"
• Designed for sail drives (e.g., SD40, SD50, etc.)
• Overdrive function for improved motor cruising
• Flexible hub for shock absorption and electrical isolation
• Low drag profile when sailing

Overdrive Function

The Overdrive feature allows the helmsman to adjust pitch and profile dynamically while underway. This delivers the same cruising speed at lower RPM, reducing fuel consumption, engine noise, and vibration—all without hydraulics or complex mechanics.

Performance Under Sail

• Folding blades reduce drag to the minimum
• Independent tests confirm increased speed under sail
• Prevents entanglement with seaweed and debris
• No need for shaft brake with hydraulic gearboxes

Performance Under Engine

Tests confirm up to +15% higher efficiency in both forward and reverse compared to other folding or rotary-blade propellers. This is achieved through optimized blade curvature and dynamic rotation design.

Engine Compatibility

• For engines from 7 kW (10 hp) to 221 kW (300 hp)
• Also supports vessels with engines above 300 hp

Sail Drive Hub System

The Gori Saildrive Propeller hub includes a flexible core that acts as a shock absorber and provides electrical isolation from the saildrive unit, meeting engine manufacturer requirements. A built-in safety system ensures long-term durability and effective power transfer.

Compatible with popular saildrives such as Bukh, Sonic, Volvo-Penta, Yanmar, and others. Each Gori propeller is individually numbered for quality assurance and future support.
