Claims
- 1. A method of making a propeller hub for a marine drive having a propeller shaft with a tapered outer diameter receiving said propeller hub therearound, the method comprising providing a propeller hub with a two stage bore having a first section of given inner diameter and a second section of larger inner diameter than said given inner diameter, machining said bore along a taper angle to form a first tapered inner diameter section at the first bore section for flush contact with said propeller shaft, a second tapered inner diameter section at said second bore section for flush contact with said propeller shaft, and a central inner diameter section at said second bore section and between said first and second tapered inner diameter sections, said central inner diameter section meeting said second tapered inner diameter section at a transition angle defined by said taper angle of said machining, mounting said propeller hub on said propeller shaft, said central inner diameter section meeting said first tapered inner diameter section at the interface between said first and second bore sections, said central inner diameter section being spaced from said propeller shaft by a maximum gap at said interface, and by no gap at said transition angle.
