Gori 3 Blade Folding Propeller 22x16x3RH1:10W for 40 mm ISO Shaft

Gori Propeller 22x16x3RH 1:10W40 - Folding Propeller

The 3-blade Gori folding propeller was launched in 1994 and in the same year received the DAME Award and HISWA Award for the best new marine product.

The 3-blade Gori folding propeller marks a technological and functional advance in the development of propellers for sailing yachts. Now both larger sailing yachts and motor sailers can achieve the speed advantages of the folding propeller under sail combined with the thrust of the fixed propeller under motor.

Due to the wing curvature of the 3-flg. Gori folding propeller creates excellent thrust ahead and by turning the wings, the same power is also achieved backwards, i.e. more power and better maneuvering properties than with almost all other propellers.

'Overdrive' function

The "Overdrive" -Function of the 3-blade Gori folding propeller gives motorized driving a new dimension. The helmsman can change the pitch and profile of the propeller when moving forward. This is controlled via the boat's single lever shift without the use of delicate hydraulics or complicated mechanics.

The “overdrive” is used under power in calm weather or when powering under sail. The "overdrive" gives the same speed at lower revs. This means less engine noise, less vibration and reduced fuel consumption.

The function is simple. In order to get from normal ahead to "overdrive", switch to reverse via idle, the ship must move clearly backwards, then switch back to ahead. To return from "overdrive" to normal ahead, shift gears to neutral, propeller folds, shift back to ahead.

The "overdrive" function and turning the propellers when maneuvering is unique and distinguishes the Gori 3 flg. Folding propeller from all other propellers.

Suitable for engines from 7kW (10hp) - 221kW (300hp)

Folding propellers were previously mainly reserved for small and medium-sized sailing yachts with relatively low engine power. Now available for engines over 300 hp. Large sailing yachts and motor sailers can now also use the special advantages of the Gori 3-bladed propeller.

The result of the special design of the Gori propeller is a minimum of noise and vibration, which is often a problem with rotary blade propellers with flat blades.\n The 3-blade Gori folding propeller comes in diameters from 15” to 30” for standard shafting and 15” to 20” for saildrive configurations.

Advantage under sail

The low profile when folded gives the lowest drag of all 3 -flg. Folding and rotary blade propellers. Independent tests have proven this effect. This results in an increase in boat speed under sail. This increase in speed increases the overall value of your boat. Why sail slowly?

The shape of the folding propeller prevents seaweed, plastic bags and other flotsam from getting caught on it and the propeller from opening when sailing. With hydraulic gearboxes, therefore, the expensive installation of a shaft brake can be dispensed with without jeopardizing the durability of the gearbox.

Performance under engine

Tests by the leading yachting magazines and other independent organizations have shown that the 3rd flg. Gori folding propeller has a significant has higher efficiency in advance (+15%) and reverse (+15%) compared to other folding or rotary blade propellers. This high level of efficiency is due to the special curvature and rotation of the propeller blades. Rotary blade propellers have a flat blade design, which means that under-powered thrust is not optimized.
