Gori 15x9x3RH Folding Propeller – 3-Blade, Ø15", Pitch 9", Right-Hand, for 30 mm ISO Shaft with Overdrive Function

The Gori Propeller 15x9x3RHx1:10W30 is an advanced 3-blade folding propeller designed for 30 mm ISO shafts. Introduced in 1994 and recognized with both the DAME Award and HISWA Award, it offers an outstanding blend of sailing speed and motoring thrust for sailing yachts and motor sailers alike.

Key Features

• 3-blade folding propeller for enhanced sailing performance
• Overdrive function for pitch adjustment under power
• Superior thrust in forward and reverse
• Minimized vibration and engine noise
• Constructed from premium Nibral and stainless steel

Technical Specifications

• Diameter: Ø15"
• Pitch: 9"
• Blades: 3
• Rotation: Right-Hand (RH)
• Shaft: 30 mm ISO Shaft (1:10 taper)
• Engine Compatibility: 10 hp to 300+ hp (7–221 kW+)

Overdrive Function

The Overdrive feature enables the helmsman to switch the pitch and profile of the propeller during forward motion, using only the boat's single lever shift. No hydraulics or electronics are needed. It provides the same speed at lower RPMs, cutting fuel consumption, vibration, and engine noise.

Performance Under Sail

The low-drag folded profile significantly increases sailing speed, as validated by independent tests. Its hydrodynamic design avoids fouling from seaweed or plastic and eliminates the need for shaft brakes on vessels with hydraulic gearboxes.

Performance Under Engine

Tests by industry-leading yachting magazines confirm up to +15% greater efficiency in both forward and reverse modes compared to other folding or rotary blade propellers. The special curvature and blade rotation optimize thrust, even with lower engine output.

Professional Build Quality

With over 25 years of expertise, Gori Propeller is a leader in folding propeller technology. Each propeller is built to the highest standard from corrosion-resistant Nibral and stainless steel and is individually numbered for service traceability and quality assurance.
