Gori 3 blade folding propeller

Available on all products. Inboard or Outboard. The Gori Folding propeller "overdrive" function adds a new dimension to sailing under power.

The 3-blade Gori folding propeller marks a technological and functional leap forward in the development of propellers for sailboats. 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'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. The "overdrive" is used when motorsailing in fair weather or when using the engine under sail.

Looking for efficiency and less vibrations, then look no further. From the intricately designed aquadynamic shape and the ingenious folding mechanism to the precision engineering. When looking to reduce drag the Gori Racing Propeller is the choice for the majority of One Design racing yachts. The 3-blade GORI Overdrive Folding Propeller give the helm the ability to choose the pitch and profile of the blades without the use of hydraulics or complicated mechanical devices. One propeller. Two settings. When in Overdrive there is less engine noise, less vibration, and better fuel economy. It really is that simple. See more. It has the same features and operates the same way as the 3-blade GORI Propeller, with the blades pivoting degrees between forward and reverse, providing the same thrust in both directions.

End of shaft to leading edge of rudder I. The "overdrive" is used when motorsailing in fair weather or when using the engine under sail.

Remember me Log in. Lost your password? It is the only folding propeller operating the same pitch in forward and in reverse, the blades pivot 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. 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.

Geared blade design ensures that the blades open and close together giving less vibration ahead and astern. This results in one full knot of improvement in speed under sail. It does not rely solely on centrifugal force to open the blades as do many other folding propeller types. NIBRAL is far stronger in all specification areas than manganese bronze commonly used by other prop manufacturers. For the last five years my boat, a Catalina , has struggled to get through the water under power, especially against a tide or current. I installed it in the spring and it has made an amazing difference.

Which is the best folding or feathering propeller for your boat? Emrhys Barrell compares 15 props in a test of speed, thrust, drag, stopping speed and propwalk. Not much, if you want to slow your boat down by at least half a knot when you are sailing. A fixed three-bladed prop, locked in gear, exerts as much drag as hanging a bucket over the stern. The answer is, fit one of the many folding or feathering props on the market. But which one, and what are the drawbacks?

Tighten the large bolt in the centre of the puller 17 and this will draw the hub cone off of the shaft. Clean the surface of the propeller hub to ensure a good clean contact between the hub and the new zinc. Pull the inner hub 2 , flexible bushing 2. No strain or loading to the transmission. If the gear wheel 13 has been damaged or worn…it should be replaced If the flexible stops 15 have been damaged or worn…they must be replaced. Related Products. Increases efficiency thrust under power and over a greater Rpm range. The 3-blade Gori folding propeller is offered in diameters from 15" and up to 30". Algonac Propeller Puller A. Loctite Blue Installing the Propeller The propeller is delivered assembled. The result is less engine noise, less vibration and better fuel economy. Gear Wheel Now undo the retaining cap using the C-Spanner If you continue to use this site we will assume that you are happy with it. First remove the 3 x allen head bolts 5 holding the jacket 1 in place.

They are available in both LH and RH configurations for both saildrive and shaft installations. These results showed conclusively the advantages of the GORI 3-blade propeller. Astern: GORI was 6.

The propeller revolution for larger sailboats and motorsailers is emphasized by the fact that the 3-blade Gori folding propeller can be used for boats fitted with engines from approximately 10 HP 7 KW and up to approximately HP KW , and the power transfer is on the whole the same as for fixed 3-blade propellers. Use the C-Spanner 16 to tighten and align the 3 threaded holes 5 with the holes in the jacket. You may use a hammer with care, to get the jacket started as it is a firm fit. Slide the blade housing assembly onto the hub cone 4 , making sure that the tabs engage the hub cone. Remember me Log in.
