Abstract
A marine drive (10) has a driveshaft housing (20) including a bell housing (22) with an exhaust passage (30) therethrough directing exhaust gas and cooling water, and a shift shaft (34) extending through the exhaust passage and journaled in the bell housing by a bushing (52) in a bore (38) in a section (40) of the bell housing. The interface (50) of the bushing and the bore is subject to corrosion from exhaust gas and cooling water. Shifting is eased by enabling a portion (54) of the bushing to contract radially inwardly toward the shift shaft (34) due to the noted corrosion, without binding the shift shaft and otherwise impeding rotation thereof.
