ABSTRACT:
A spider differential assembly (7) of a marine drive is constructed so that the spider (16) and its associated spider pinion gears (20) can float in all directions, except about the common central axis (5) of the propeller drive shafts (4, 8). More particularly, a spider is provided with a central hub opening (18) through which the main drive shaft passes. A plurality of radially extending spindles (19) carry the spider gears and extend outwardly where they terminate in an enclosure (30, 31) arranged to prevent circumferential spider movement about the common drive shaft axis, but which permits free spider floating.
