Abstract
A marine drive shift mechanism includes a shift ring (200) having a chamfer zone (204) along an arcuate portion of its outer circumference facilitating ease of shifting. A stepped camming surface (222) provides step function shifting movement. Neutral positioning notches (238, 240) are provided on the clutch sleeve (18) to improve clutch sleeve (18) placement when the shift mechanism is in neutral.
