A marine propulsion device comprising a propulsion unit including an internal combustion engine, the engine comprising a cylinder, a water jacket, a water jacket inlet port communicating with the water jacket, and a lower face having therein an exhaust outlet port communicating with the cylinder, the propulsion unit also including a drive shaft housing having a lower end, a gearcase connected to the lower end of the drive shaft housing, a propeller rotatably supported by the gearcase, a drive shaft which extends through the drive shaft housing and which includes an upper end driven by the engine and a lower end drivingly connected to the propeller, and an exhaust housing located at least partially within the drive shaft housing and connected to the lower face of the engine, the exhaust housing comprising an exhaust passage located interiorly of the exhaust housing and communicating with the exhaust outlet port, a water intake port, and a water intake passage located interiorly of the exhaust housing and communicating between the water intake port and the water jacket inlet port, and a water pump having an outlet communicating with the water intake port.

Marine propulsion device

A marine propulsion lower unit including a gear case supporting a propeller shaft adapted to carry a propeller, which gear case has an upper surface including therein a cylindrical well defined by cylindrical peripheral wall and a bottom wall having therein an axial bore, a combined shift rod bushing and gear case seal assembly comprising a hub having an axis and axially spaced first and second ends, which hub also includes therein an axial bore extending from the first end, and which hub also includes therein a counter bore extending from the second end, and communicating with the axial bore in coaxial relation thereto, a flange extending from the hub and received in the well in the gear case, a pair of attachment arms extending from the hub in transverse radially outward relation to the axis of the hub and fixedly connected to the gear case, a plug member received in the counter bore and having an axial bore communicating with the axial bore in the hub, a shift rod extending through the axial bore in the plug member and through the axial bore in the hub, a first seal between the flange and the gear case, and a second seal between the plug member and each of the hub and the shift rod.

Combined shift rod bushing and gear case seal for marine propulsion

A marine propulsion device comprising a transom bracket adapted to be mounted on the transom of a boat and having a side and upper surface, the marine propulsion device further comprising a swivel bracket mounted on the transom bracket for pivotal movement relative to the transom bracket about a generally horizontal tilt axis and between an operating position and a raised position, a propulsion unit including a rotatably mounted propeller and being mounted on the swivel bracket for pivotal movement relative to the swivel bracket about a generally vertical steering axis, a tilt lock shaft having first and second ends extending through the swivel bracket along a second generally horizontal axis spaced rearwardly from and substantially parallel to the tilt axis, a lever member mounted on the shaft and including a contact pad extending parallel to and radially offset from the second axis and further including at least one leg extending substantially perpendicularly relative to the contact pad, and manually operable structure for rotating the tilt lock shaft between a lock position, wherein the leg extends along the side of the transom bracket and the contact pad engages the upper surface of the transom bracket to prevent movement of the swivel bracket from the raised position to the operating position, and a release position wherein the contact pad disengages the transom bracket to permit the swivel bracket to move from the raised position to the operating position.

Outboard motor tilt lock device

Disclosed herein is a marine propulsion device comprising a lower unit including a gear case rotatably supporting a propeller shaft adapted to support a propeller, which gear case includes an interior passage leading to a water pump, which gear case also includes a leading edge and opposite side surfaces having outwardly convex configurations extending rearwardly from the leading edge, one of the side surfaces including a cooling water inlet comprising an opening located in the one side surface, communicating with the interior passage, and defined by forward and rearward walls, a recess located in the one side surface forwardly of the opening and having a rearward end located at the forward wall of the opening and a forward end, which recess increases in lateral depth from the forward end to the rearward end, and a screen located in the opening and including an inclined portion extending outwardly and rearwardly from the forward wall of the opening, and a side portion extending rearwardly from the inclined portion to the rearward wall of the opening, which screen also includes a series of horizontal parallel slots located in the inclined and side portions and affording inflow of cooling water to the passage.

Marine propulsion device with screened water inlet

A marine propulsion device comprising a mounting bracket adapted to be mounted on the transom of a boat, a propulsion unt mounted on the mounting bracket for pivotal movement relative thereto about a generally vertical steering axis, the propulsion unit including a pivotally mounted propeller and an engine drivingly connected to the propeller by a transmission, and a shift handle assembly including an inner member mounted on the propulsion unit for movement relative thereto, the inner member being connected to the transmission for actuation of the transmission in response to movement of the inner member, an outer member movable between spaced first and second positions relative to the inner member, and a bolt for securing the outer member in the first position so as to cause movement of the inner member in response to movement of the outer member, and for selectively permitting movement of the outer member to the second position.

Marine propulsion device with releasable shift handle

A marine propulsion device comprising a lower unit including a rotatably mounted propeller, and an internal combustion engine drivingly connected to the propeller, the engine including an engine block, a crankshaft rotatably supported by the engine block and including an end portion projecting from the engine block, a flywheel including a hub, the hub being mounted on the end portion of the crankshaft and having an outer surface, and a bearing located between the engine block and the outer surface of the flywheel hub for facilitating rotation of the flywheel relative to the engine block.
