Autostream Self Feathering Propellers

English Brochure Deutsche Broschüre Nederlandstalige Brochure

The Autostream self-feathering propeller has evolved through 8 models, over more than thirty years. Many experienced sailors tell us they consider the Autostream propeller to be the best propeller of its type available – a fact we are proud of. They offer excellent propulsion, control and low-drag. We know by the fact we sell very few parts, that the reliability and robustness is second to none. Self-feathering propellers are the propeller of choice for most cruising sailors. It is also ideal for those with difficult docking conditions, hard to handle sailboats or those that just like the reassurance of extra control – all with little drag whilst sailing.

  • New blade design is up to 20% more efficient than previous model
  • Use of Duplex 2507 for the blades allows a very thin cross section, while retaining great strength
  • Body components cast in 316L
  • "O" ring seals on the blades and main gear hub prevent loss of grease
  • Simple screw and locknut pitch adjustment can be adjusted easily, even while in the water
  • Independent ahead and astern pitch adjustment, allows optimum ahead pitch and fine reverse pitch for maximum thrust and minimum "prop walk"
  • Dual blade bearings support the blade either side of the gear for increased rigidity
  • Oversize dowels locate blade assembly and transmit driving torque
  • 6 x 8mm cap head screws lockwired in place for security provide a very robust construction
  • Sacrificial zinc anode tail cone with stainless steel core. A single Nylok nut makes in water replacement easy
  • Single permanently fitted grease nipple/"zerk" lubrication point, enables easy in water lubrication of all bearing areas (required annually)
