Craftsman Marine propellers are machined with a tapered shaft hole (1:10) and a keyway.
They are well balanced and finely machined at the edges to prevent propeller singing. The propellers are made from manganese bronze and have a Fa/F ratio of 0,52 (52% blade surface). The range of propellers offered by Craftsman Marine is extensive, with a variety of dimensions in regard to diameter and pitch. Our propellers are produced to operate at the highest efficiency and minimal noise production and vibrations.
