Marine propulsion device with access opening
View Patent ↗A marine propulsion device is provided with an access opening through a portion of its gimbal housing. At least two support locations, formed integrally with the gimbal housing, provide locations to support a swivel shaft that attaches a gimbal ring to the gimbal housing. A steering lever is attached to the swivel shaft at a location between the points of support. The shaft extends through cylindrical holes in both support portions of the gimbal housing and a nut extends at least partially through one of the cylindrical holes to retain the swivel shaft and steering lever in position. The nut is removable from the shaft by accessing the nut through the opening formed in the support structure of the gimbal housing.
1. A marine propulsion device comprising:
a gimbal housing which is attachable to a transom of a marine vessel;
a gimbal ring rotatably supported by said gimbal housing;
a shaft rotatably supported by said gimbal housing and attached to said gimbal ring, said shaft being rotatable about a steering axis;
a steering lever connected to said shaft;
a nut attached to a threaded portion of said shaft, said nut and said steering lever being configured to rigidly attach said steering lever to said shaft, said steering lever being rotatable about said steering axis;
a first cylindrical hole formed through a first portion of said gimbal housing;
a second cylindrical hole formed through a second portion of said gimbal housing, said first and second cylindrical holes being coaxial with each other and with said steering axis;
wherein said nut extends into and at least partially through said first cylindrical hole.
2. The marine propulsion device according to claim 1 wherein said nut has an outer cylindrical surface rotatably supported in said first cylindrical hole.
3. The marine propulsion device according to claim 2 comprising a bushing disposed in said first cylindrical hole, and wherein said outer cylindrical surface of said nut is rotatably supported within said bushing.
4. The marine propulsion device according to claim 3 wherein said first cylindrical hole has an inner surface, and said bushing is disposed radially between said outer cylindrical surface of said nut and said inner surface of said first cylindrical hole.
5. The marine propulsion device according to claim 1 comprising an access opening formed in said gimbal housing, said steering axis extending through said access opening, and a cover which is removably attached to said gimbal housing and disposable over said access opening.
6. The marine propulsion device according to claim 1 wherein said steering lever is retained between said nut and said second portion of said gimbal housing.
7. The marine propulsion device according to claim 6 wherein said steering lever is disposed between said first and second portions of said gimbal housing.
8. The marine propulsion device according to claim 1 wherein said steering lever is retained between said nut and said gimbal housing, and said steering lever is disposed between said first and second cylindrical holes.
