I have a folding propeller, what is the advantage of fitting an Autostream self-feathering propeller?
The drag would be slightly more than a two blade folding and about the same as a three blade- folding propeller. Stopping and reversing power would be significantly improved. Ahead performance would be similar and in most cases improved due to the ability of the Autostream Propellers pitch to be easily adjusted to tune the propeller to suit the engine and boat. The life of an Autostream Propeller will be at least three times greater than a folding propeller due to the moving parts being permanently lubricated and protected from the elements. The fact that the Autostream is made of stainless steel, the same material as most propeller shafts, plus a significant zinc anode right on the propeller reduces the possibility of damage due to electrolysis, the main cause of propeller failure, especially in folding propellers.
