Gori 3 Blade Folding Propeller 18X12X3LHS-SD40-60 for SD 50 Sail Drive

Gori Propeller 18X12X3LHS-SD40-60 - Folding Propeller 18x12x3LHS for SD 50 Sail Drive

The Gori Propeller 18X12X3LHS-SD40-60 represents a groundbreaking 3-blade folding propeller that debuted in 1994, earning prestigious accolades such as the DAME Award and HISWA Award for its innovation in marine products. This propeller signifies a significant technological leap in the realm of sailing yachts, providing both larger sailing vessels and motor sailers with the dual benefits of enhanced speed under sail and the thrust of a fixed propeller under motor power.

Characterized by the distinctive wing curvature, the 3-blade Gori folding propeller excels in creating exceptional thrust in both forward and reverse, surpassing the performance of most other propellers in the market. The introduction of the unique "Overdrive" function elevates motorized driving, allowing the helmsman to dynamically adjust pitch and profile when moving forward, seamlessly controlled via the boat's single lever shift without the need for delicate hydraulics or complex mechanics.

Designed to operate under power in calm weather or while sailing, the "Overdrive" function delivers the same speed at lower revs, resulting in reduced engine noise, vibration, and fuel consumption. The operational simplicity involves switching to reverse via idle to move the ship clearly backward, then switching back to ahead. Returning from "overdrive" to normal ahead involves shifting gears to neutral, allowing the propeller to fold, and then shifting back to ahead, making it a distinctive feature that sets the Gori 3-blade folding propeller apart from its counterparts.

Suitable for engines ranging from 7kW (10hp) to 221kW (300hp), this folding propeller extends its capabilities beyond small and medium-sized sailing yachts to accommodate engines over 300 hp, catering to large sailing yachts and motor sailers. The special design minimizes noise and vibration, common issues with rotary blade propellers with flat blades. Available in diameters from 15” to 30” for standard shafting and 15” to 20” for saildrive configurations, the Gori 3-blade folding propeller offers a diverse range of options to suit various vessel requirements.

Under sail, the low profile when folded contributes to the lowest drag among 3-blade folding and rotary blade propellers, as confirmed by independent tests. This results in an increased boat speed under sail, enhancing the overall value of your boat. The shape of the folding propeller prevents seaweed, plastic bags, and other debris from getting caught on it, ensuring a smooth sailing experience. Additionally, with hydraulic gearboxes, the expensive installation of a shaft brake can be avoided without compromising the durability of the gearbox.

Performance under engine power has been extensively tested by leading yachting magazines and independent organizations, demonstrating a significant increase in efficiency both in advance (+15%) and reverse (+15%) compared to other folding or rotary blade propellers. This heightened efficiency is attributed to the special curvature and rotation of the propeller blades, optimizing thrust even with underpowered engines.

Specifically designed for saildrive configurations, the Gori Saildrive Propeller features a hub with a flexible core that acts as a shock absorber, electrically isolating the propeller from the saildrive, as required by engine manufacturers. A safety system in the hub enhances durability and ensures maneuverability at all times. The propeller has been meticulously designed to be compatible with popular sail drives such as Bukh, Sonic, Volvo-Penta (including 50S and 100S drives), Yanmar, and others, further expanding its versatility.
