Outboard motor capable of being tilted up and trimmed in, and marine vessel therewith

Abstract

An outboard motor includes a main body including a power source and a bracket to be attached to a stern of a hull. The main body is rotatable about a rotating shaft of the bracket such that an upper portion of the main body moves toward a front of a marine vessel and a lower portion of the main body moves toward a rear of the marine vessel, or such that the upper portion of the main body moves toward the rear of the marine vessel and the lower portion of the main body moves toward the front of the marine vessel. When the marine vessel is cruising, a distance from the rotating shaft to an upper end of the stern in a vertical direction of the marine vessel is equal to or longer than a distance from the rotating shaft to a propeller shaft in the vertical direction of the marine vessel.

What is claimed is: 
     
         1 . An outboard motor comprising:
 a main body including a power source;   a bracket to be attached to a stern of a hull of a marine vessel and including a rotating shaft; and   a propeller shaft to rotate a propeller at a lower portion of the main body; wherein   the main body is attached to the bracket and rotatable in a first direction and a second direction;   in the first direction, the main body is rotatable about the rotating shaft such that an upper portion of the main body moves toward a front of the marine vessel and the lower portion of the main body moves toward a rear of the marine vessel;   in the second direction, the main body is rotatable about the rotating shaft such that the upper portion of the main body moves toward the rear of the marine vessel and the lower portion of the main body moves toward the front of the marine vessel; and   when the marine vessel is cruising, a first distance from the rotating shaft to an upper end of the stern in a vertical direction of the marine vessel is equal to or longer than a second distance from the rotating shaft to the propeller shaft in the vertical direction of the marine vessel.   
     
     
         2 . The outboard motor according to  claim 1 , wherein, when the marine vessel is cruising, the first distance is twice or more as long as the second distance. 
     
     
         3 . The outboard motor according to  claim 1 , wherein, with respect to a fore-and-aft direction of the hull, the rotating shaft is more rearward than a rear end of the stern. 
     
     
         4 . The outboard motor according to  claim 1 , wherein, in the second direction, the main body rotates about the rotating shaft by a rotation angle of about 20° or more. 
     
     
         5 . The outboard motor according to  claim 1 , wherein, in the second direction, the main body rotates about the rotating shaft by a rotation angle of about 30° or more. 
     
     
         6 . The outboard motor according to  claim 1 , wherein a posture control plate that rotates with respect the vertical direction of the marine vessel is not provided at the stern of the hull. 
     
     
         7 . The outboard motor according to  claim 1 , further comprising a lift to move the main body in the vertical direction of the marine vessel. 
     
     
         8 . The outboard motor according to  claim 7 , wherein the lift is operable to change a position of the main body in the vertical direction of the marine vessel when the marine vessel is cruising. 
     
     
         9 . The outboard motor according to  claim 7 , wherein the marine vessel includes hydrovanes, and the lift is operable to move the main body downward to a lower side of the hull when the marine vessel is foilborne cruising. 
     
     
         10 . The outboard motor according to  claim 7 , wherein, to store the marine vessel, the lift raises the main body, and the main body rotates in the first direction. 
     
     
         11 . The outboard motor according to  claim 1 , wherein the power source includes an electric motor. 
     
     
         12 . A marine vessel comprising:
 an outboard motor including a main body including a power source;   a bracket attached to a stern of a hull of the marine vessel and including a rotating shaft; and   a propeller shaft to rotate a propeller at a lower portion of the main body; wherein   the main body is attached to the bracket and rotatable in a first direction and a second direction;   in the first direction, the main body is rotatable about the rotating shaft such that an upper portion of the main body moves toward a front of the marine vessel and a lower portion of the main body moves toward a rear of the marine vessel;   in the second direction, the main body is rotatable about the rotating shaft such that the upper portion of the main body moves toward the rear of the marine vessel and the lower portion of the main body moves toward the front of the marine vessel; and   when the marine vessel is cruising, a first distance from the rotating shaft to an upper end of the stern in a vertical direction of the marine vessel is equal to or longer than a second distance from the rotating shaft to the propeller shaft in the vertical direction of the marine vessel.   
     
     
         13 . An outboard motor comprising:
 a main body including a power source; and   a bracket to be attached to a stern of a hull of a marine vessel and including a rotating shaft; wherein   the main body is attached to the bracket and rotatable in a first direction and a second direction;   in the first direction, the main body is rotatable about the rotating shaft such that an upper portion of the main body moves toward a front of the marine vessel and a lower portion of the main body moves toward a rear of the marine vessel;   in the second direction, the main body is rotatable about the rotating shaft such that the upper portion of the main body moves toward the rear of the marine vessel and the lower portion of the main body moves toward the front of the marine vessel; and   in a vertical direction of the marine vessel, the rotating shaft is closer to a lower end of the stern than to an upper end of the stern.   
     
     
         14 . An outboard motor comprising:
 a main body including a power source; and   a bracket to be attached to a stern of a hull of a marine vessel and including a rotating shaft; wherein   the main body is attached to the bracket and rotatable in a first direction and a second direction;   in the first direction, the main body is rotatable about the rotating shaft such that an upper portion of the main body moves toward a front of the marine vessel and a lower portion of the main body moves toward a rear of the marine vessel;   in the second direction, the main body is rotatable about the rotating shaft such that the upper portion of the main body moves toward the rear of the marine vessel and the lower portion of the main body moves toward the front of the marine vessel; and   in a vertical direction of the marine vessel, the rotating shaft is closer to a lower end of the main body than to an upper end of the main body.
