Our Part #: GOR3BLADERSD20 | Mfr. Part #: 3 BLADE SSO 20.0
Shaft: 38 to 50 mm
Diameter: 20 in
Pitch Range: 12 to 16
The 3-blade Gori Folding Propeller marks a technological and functional leap forward in the development of propellers for sailboats. It is the only folding propeller operating the same pitch in forward and in reverse, the blades pivot 180 degree. It is now possible for sailboats and motorsailers to gain the folding propeller's speed advantages under sail, combined with the fixed propeller's thrust capability when motoring. The 3-blade Gori Folding Propeller was introduced on the market in 1994 and won the DAME award and HISWA award the same year, as the best new marine product.
Overdrive Function, less is more
The 3-blade Gori Folding Propeller's Overdrive function adds a new dimension to sailing under power. The helmsman can choose the propeller pitch and profile in the water while sailing forward by regulating the yacht's shift and throttle control. Without the use of vulnerable hydraulics or complicated mechanical devices. Used when motorsailing in fair weather or when using the engine under sail. Overdrive provides the same speed at lower rpms resulting in less engine noise, less vibrationand better fuel economy.
Full Speed Under Sail
Traditionally, folding propellers are best suited for small and medium size sailboats with moderate engine sizes. However, the 3-blade Gori Folding Propeller’s unique design brings these advantages within the reach of larger sailboats and motorsailers. The extra speed under sail is substantialand the unique design prevents seaweed etc. snagging the propeller. Tests by major yachting magazines have shown that the 3-blade Gori Folding Propeller has a much better efficiency both forward (+11%) and reverse (+6,5%) than a feathering propeller.
Practically designed for most engine sizes
The 3-blade Gori Folding Propeller is offered in diameters from 15" and up to 30", for boats fitted with engines from approximately 10 HP (7 KW) and up to approximately 300 HP (221 KW). The 3-blade Gori Folding Propeller is manufactured in the same professional quality, where every single propeller has its own number and a "logbook" during production. Each propeller is balanced dynamically.
