Gori 16.5x10x3LHx1:10W25 Folding Propeller – 3-Blade, Ø16.5", Pitch 10", Left-Hand, for 25 mm ISO 1:10 Shaft
The Gori Propeller 16.5x10x3LHx1:10W25 is a premium 3-blade folding propeller, first introduced in 1994 and awarded the DAME and HISWA Awards for its groundbreaking innovation in marine propulsion. Designed for sailing yachts and motor sailers, it offers the benefits of both folding and fixed propellers—low drag under sail and strong thrust under engine power.
Key Features
- 3-blade folding design for reduced drag under sail
- Left-hand rotation, Ø16.5", pitch 10"
- Fits 25 mm ISO 1:10 tapered shaft
- Overdrive function for efficient motoring at lower RPMs
- Quiet and low-vibration operation
Overdrive Function
The innovative Overdrive function allows dynamic pitch and blade profile adjustment through a single lever control, without the need for hydraulics or complex mechanics. It enables the same cruising speed at lower engine revs, reducing noise, fuel use, and vibration.
Engine Compatibility
- Engine range: 7 kW (10 hp) to 221 kW (300 hp)
- Also available for vessels with engines above 300 hp
Performance Under Sail
- Lowest drag among 3-blade folding propellers when folded
- Prevents seaweed or debris from catching during sailing
- Eliminates need for a shaft brake on hydraulic gearboxes
Performance Under Engine
Independent tests confirm that the Gori folding propeller provides up to +15% more efficiency in both forward and reverse compared to other folding or rotary blade designs. This performance is achieved through optimized blade curvature and rotation.
Construction & Quality
Made from high-grade Nibral and stainless steel, every Gori propeller is individually numbered for traceability and service. With over 25 years of industry leadership, Gori remains the preferred choice of yacht designers, builders, and regatta sailors worldwide.
