ABSTRACT:
A marine propulsion device comprising a lower unit including a gearcase, a propeller shaft mounted in the gearcase for rotation about a generally horizontal fore and aft axis and having an axially extending forwardly opening bore, a shift shaft including a rearward portion located in the bore, a forward portion, and structure for connecting the forward portion to the rearward portion to effect common axial movement of the forward and rearward portions in both directions along the fore and aft axis, a shift lever supported by the lower unit for rotary movement about a horizontal axis transverse to the fore and aft axis, being adapted to be connected to a vertically shiftable link to thereby rock the lever about the transverse horizontal axis, and including a leg, and structure for connecting the leg to the forward portion of the shift shaft to effect movement of the forward portion of the shift shaft in both directions along the fore and aft axis in response to rotary shift lever movement, one of the structure for connecting the forward portion of the rearward portion and the structure for connecting the leg to the forward portion including assembling structure operable incident to forward displacement of the rearward portion of the shift shaft to effect such connection thereof so as thereafter to effect displacement of the shift shaft in both directions along the fore and aft axis in response to rocking movement of the shift lever about the transverse horizontral axis.
