Gori 11.5x8x2RHS-50S Folding Propeller – 2-Blade, Ø11.5", Saildrive, RH, for Volvo Penta MB2A 50S

The Gori 11.5x8x2RHS-50S is a high-performance 2-blade folding propeller designed for sailing yachts with engines up to 44 kW (60 hp). This model is tailored for saildrive installations such as the Volvo Penta MB2A 50S, offering right-hand (RH) rotation and a 11.5” diameter with 8” pitch. Built on over 25 years of refinement, the Gori folding propeller combines efficiency, innovation, and durability.

Key Features:
- Diameter: 11.5” / Pitch: 8” / Rotation: Right-hand (RH)
- Drive Type: Saildrive (e.g. Volvo Penta MB2A 50S, 100S, Bukh, Sonic, Yanmar)
- Wing Synchronization: Toothed blade connection ensures minimal vibration
- Automatic Folding: Wings fold under sail, reducing drag by up to 35%
- Sailing Speed Gain: Up to 1 knot increase under sail
- Debris Resistance: Blade design prevents snagging by seaweed or plastic
- Flexible Hub: Integrated shock-absorbing core for protection and insulation
- Reverse Efficiency: Equal to or better than 2- or 3-blade folding and fixed props
- Forward Drive Efficiency: Exceeds most conventional rotary and folding designs
- Material: High-strength, corrosion-resistant marine alloys
Performance Advantages:

This propeller ensures smooth propulsion with reduced vibration during powered operation. When sailing, the blades automatically fold to minimize resistance and increase boat speed. Extensive testing confirms excellent thrust and responsiveness in reverse, with a folding mechanism that relies on both blade shape and centrifugal force for consistent performance.

Compatibility:
- Engine Power: Up to 44 kW / 60 hp
- Designed for saildrive units including Volvo Penta MB2A 50S, 100S
- Also suitable for: Bukh, Sonic, Yanmar saildrives (with matching specifications)
Benefits:
- Maximizes sailing performance with reduced drag and better speed
- Delivers high thrust and efficiency in both forward and reverse
- Minimizes engine and drivetrain vibration for smoother operation
- Flexible hub protects drivetrain and meets OEM isolation standards
- Proven performance in both cruising and racing conditions
The Gori 11.5x8x2RHS-50S folding propeller is ideal for discerning sailors who demand optimal performance, efficiency, and reliability in all sailing and motoring conditions.
