Claim 1
Independent Claim
87 words
In a marine propulsion device, the combination of a support, a power shaft mounted on said support and extending horizontally adjacent to and generally parallel to the stern of a boat, a housing mounted on and extending from said support for pivotal movement about the axis of said power shaft, a driven shaft carried by said housing and extending normal to said power shaft, and a reversing clutch connecting said power shaft and said driven shaft and including an actuating shaft extending axially through said power shaft.
Claim 2
Dependent Claim
87 words
In a marine propulsion device, the combination of a support, a power shaft mounted on said support and extending horizontally adjacent to and generally parallel to the stern of a boat, a housing mounted on and extending from said support for pivotal movement about the axis of said power shaft, a driven shaft carried by said housing and extending normal to said power shaft, and a reversing clutch connecting said power shaft and said driven shaft and including an actuating shaft extending axially through said power shaft.
Claim 3
Dependent Claim
141 words
In a marine propulsion device, the combination of a support, a housing mounted on and extending from said support for pivotal movement about a horizontal axis, a power shaft rotatably mounted on said housing and extending horizontally adjacent to the stern of a boat and coaxially with said horizontal axis, said power shaft having an axial bore extending from at least one end thereof, a driven shaft carried by said housing and extending normal to said power shaft, reverse and forward driving gears rotatably mounted coaxially with said power shaft within said housing, a clutch between said power shaft and said reverse and forward gears, a clutch actuating shaft extending through said power shaft bore and extending exteriorly of said housing from one end thereof, and a gear on said driven shaft in driving connection with said reverse and forward gears.
Claim 4
Dependent Claim
141 words
In a marine propulsion device, the combination of a support, a housing mounted on and extending from said support for pivotal movement about a horizontal axis, a power shaft rotatably mounted on said housing and extending horizontally adjacent to the stern of a boat and coaxially with said horizontal axis, said power shaft having an axial bore extending from at least one end thereof, a driven shaft carried by said housing and extending normal to said power shaft, reverse and forward driving gears rotatably mounted coaxially with said power shaft within said housing, a clutch between said power shaft and said reverse and forward gears, a clutch actuating shaft extending through said power shaft bore and extending exteriorly of said housing from one end thereof, and a gear on said driven shaft in driving connection with said reverse and forward gears.
Claim 5
Dependent Claim
101 words
In a marine propulsion device, the combination of a support, a power shaft mounted on said support and extending horizontally adjacent to the stern of a boat, a housing mounted on and extending from said support for pivotal movement about the axis of said power shaft, a pair of bevel gears rotatably mounted concentrically with said power shaft within said housing, a drive shaft carried by said housing and extending normal to said power shaft and having thereon a bevel gear in mesh with said pair of bevel gears, and a reversing clutch connecting said power shaft and said bevel gears.
Claim 6
Dependent Claim
101 words
In a marine propulsion device, the combination of a support, a power shaft mounted on said support and extending horizontally adjacent to the stern of a boat, a housing mounted on and extending from said support for pivotal movement about the axis of said power shaft, a pair of bevel gears rotatably mounted concentrically with said power shaft within said housing, a drive shaft carried by said housing and extending normal to said power shaft and having thereon a bevel gear in mesh with said pair of bevel gears, and a reversing clutch connecting said power shaft and said bevel gears.
Claim 7
Dependent Claim
64 words
A device in accordance with claim 2 wherein said housing includes arcuate bearing surfaces located coaxially with said horizontal axis and inwardly of said one end of said housing and said support includes bearing surfaces meeting with said housing bearing surfaces and being, at least at one end, horizontally open, whereby at least said one end of said housing is uncovered by said support.
Claim 8
Dependent Claim
41 words
A device in accordance with claim 2 wherein said housing also includes means defining a cavity containing said clutch and means defining a water jacket at least partially surrounding said clutch cavity and means for supplying water to said water jacket.
