ABSTRACT:
Drive engaging linkage (2) for a marine drive lower gear case (4) includes linkage (38) for converting translational movement of an operator controlled stalk (32) into axial movement of an inner axial control shaft (20) within a propeller shaft (6) to in turn slide a clutch (18) axially along the outside of the propeller shaft into engagement with drive gear means (8). The stalk (32) and linkage (38) are part of a pre-assembled subassembly (66) inserted downwardly into the gear case. The linkage includes a crank (40) pivoted at a point (42) on the subassembly above the propeller shaft and axially spaced from the drive gears, and including a lever arm (46) loosely engaging a portion (48) of the inner control shaft extending axially beyond the drive gears.
