Claims
- 1. A marine propulsion device for a boat hull having a transom, said device comprising a steering post having a longitudinal axis and adapted to be connected to the boat transom for rotation about said longitudinal axis, a propulsion assembly including a rotatably mounted propelling element, and means connecting said propulsion assembly and said steering post for common pivotal movement about said longitudinal axis and for movement of said propulsion assembly relative to said steering post between a running position and a second position elevated from the running position and against steering movement of said propulsion unit assembly relative to said steering post, said means connecting said propulsion assemby and said steering post including means for selectively and rectilinearly displacing said propulsion unit assembly relative to said steering post between said running position and said second position, said means for selectively and rectilinearly displacing said propulsion assembly comprising a hydraulic cylinder having an axis and a piston moveable in and relative to said cylinder along said cylinder axis, means connecting said cylinder to said steering post with said cylinder axis in fixed relation to said steering post, and means connecting said propulsion assembly to said piston for common movement therewith and for connecting said propulsion assembly to said cylinder for propulsion assembly movement axially of said cylinder.
- 2. A marine propulsion device for a boat hull having a transom, said device comprising a steering post having a longitudinal axis and adapted to be connected to the boat transom for rotation about said longitudinal axis, a propulsion assembly including a rotatably mounted propelling element, and means connecting said propulsion assembly and said steering post for common pivotal movement about said longitudinal axis and for movement of said propulsion assembly relative to said steering post between a running position and a second position elevated from the running position and against steering movement of said propulsion unit assembly relative to said steering post, said means connecting said propulsion assembly and said steering post including means for selectively and rectilinearly displacing said propulsion unit assembly relative to said steering post between said running position and said second position, said means for selectively and rectilinearly displacing said propulsion assembly comprising a link which is extensible and contractable and which is connected, at one end, to said steering post and connected, at the other end, to said propulsion assembly, and means cooperating with said link for preventing pivotal movement in a vertical plane of said propulsion assembly with respect to said link.
- 3. A marine installation comprising a boat hull including a transom, a steering post having a longitudinal axis and rotatably carried by and aft of said transom about said longitudinal axis, a propulsion unit assembly including a rotatably mounted propelling element, and means connecting said propulsion unit assembly and said steering post for common pivotal movement about said longitudinal axis and for movement of said propulsion unit assembly relative to said steering post between a running position and a second position spaced from the running position and against other material movement of said propulsion unit assembly relative to said steering post, said means connecting said propulsion unit assembly and said steering post including means providing rectilinear movement of said propulsion unit assembly relative to said steering post between said running position and said second position, said means providing rectilinear movement of said propulsion assembly comprising a link which is extensible and contractable and which is connected, at one end, to said steering post and connected, at the other end, to said propulsion unit assembly, and further including means for preventing pivotal movement in a vertical plane of said propulsion unit assembly with respect to said link.
