Advantages of Autostream Self Feathering Propellers over Folding Propellers
The reversing performance of feathering propellers is superior to all other fixed and folding blade propellers which are designed for optimum ahead performance.
Feathering propeller blades rotate on their axis when going from forward to reverse, This presents the same leading edge of the blade to the water as in the ahead position.
Autostream propellers have independent pitch adjustment for forward and reverse
This allows pitch adjustment to achieve optimum ahead performance whilst allowing a fine pitch setting astern, giving less tendency for prop walk and maximum thrust.
have many propellers giving 20 year plus service, and in most cases these can be refurbished for around 20% of the replacement cost.
Also the material used in Autostream propellers is less prone to electrolysis.
Propellers with moving blades such as folding and feathering have poor electrical connection of components to the standard shaft anode.
It is therefore important that a substantial anode be attached directly to the propeller to give satisfactory protection.
Autostream propellers have sufficient pitch adjustment to accommodate virtually all engine/gearbox combinations.
This plus the ability to be changed from right hand rotation to left hand rotation means that in most instances the same propeller can be used should you decide to change to an engine with different specifications.
