ABSTRACT:
In a marine drive having a tapered propeller shaft section (14) and a tapered propeller hub (20, 60) matching and fitting therearound in flush contact, a relief inner diameter section (28, 66) is provided in the hub, spaced from the propeller shaft, to prevent flush contact and facilitate removal of the propeller hub from the propeller shaft. In a further embodiment, a thrust collar (50) with a substantially steeper tapered section (56) further facilitates removal.
