A synchronized gear shift mechanism is provided for a marine propulsion system. Using a hub and a sleeve that are axially movable relative to an output shaft but rotationally fixed to the shaft and to each other, the gear shift mechanism uses associated friction surfaces to bring the output shaft up to a speed that is synchronism with the selected forward or reverse gear prior to mating associated gear tooth surfaces together to transmit torque from an input shaft to an output shaft. The friction surfaces on the forward and reverse gears can be replaceable to facilitate repair after the friction surfaces experience wear.
[ I claim:] [1.] A gear shift mechanism for a marine propulsion system, comprising:an input shaft;a driving gear attached for rotation with said input shaft;an output shaft;a forward gear rotatably attached to said output shaft, said forward gear having first and second toothed surfaces and a first
[ I claim:] [1.] A gear shift mechanism for a marine propulsion system, comprising:an input shaft;a driving gear attached for rotation with said input shaft;an output shaft;a forward gear rotatably attached to said output shaft, said forward gear having first and second toothed surfaces and a first friction surface, said first friction surface being manually detachable from said forward gear;a reverse gear rotatably attached to said output shaft, said reverse gear having third and fourth toothed surfaces and a second friction surface, said second friction surface being manually detachable from said reverse gear, said first and third toothed surfaces of said forward and reverse gears being connected in meshing relation with said driving gear;a hub which is rotationally fixed to said output shaft and free to slide axially along said output shaft relative to said forward and reverse gears, said hub having a third friction surface facing said first friction surface of said forward gear, said hub having a fourth friction surface facing said second friction surface of said reverse gear;a sleeve disposed radially outward from said hub, said sleeve being rotationally fixed to said hub and free to slide axially relative to said hub, said sleeve having a fifth toothed surface facing and being axially movable relative to said second toothed surface, said sleeve having a sixth toothed surface facing and being axially movable relative to said fourth toothed surface;a detent device detachably connecting said hub to said sleeve; anda shifting mechanism for moving said sleeve axially relative to said forward and reverse gears, said hub and said sleeve being shaped to assure that said third friction surface moves into contact with said first friction surface prior to said fifth toothed surface moving into contact with said second toothed surface when said sleeve is moved axially toward said forward gear and that said fourth friction surface moves into contact with said second friction surface prior to said sixth toothed surface moving into contact with said fourth toothed surface when said sleeve is moved axially toward said reverse gear, said detent device allowing said hub and said sleeve to move relative to each other in response to a predetermined magnitude of force in an axial direction exerted on said sleeve by said shifting mechanism.
