Propulsion system for a marine vessel

Abstract

A propulsion system for a marine vessel includes a transom bracket being configured to be connected with a transom of the marine vessel, a drive unit being rotatably connected with the transom bracket so as to be pivotable from a lowered position into a raised position, or vice versa, and a trim arrangement being arranged between the transom bracket and the drive unit to adjust a trim angle of the drive unit when in the lowered position, wherein a support face is arranged on the transom of the marine vessel or at the transom bracket, and the drive unit comprises a support member arranged opposite the support face in the lowered position whereby the support face is configured to support the support member.

         3 . The propulsion system of  claim 2 , wherein the first pivot hub part and the second pivot hub part have an outer geometry enabling that the drive unit can be pivoted around the first pivot joint. 
     
     
         4 . The propulsion system of  claim 3 , wherein a section of the the first pivot hub part and the second pivot hub part each have a section radius and a segment of the drive unit has a segment radius, the section radius and the segment radius being substantially equal to match each other in different trim angles of the drive unit when in the lowered position. 
     
     
         5 . The propulsion system of  claim 1 , wherein the support face is arranged for receiving the support member in different trim angles of the drive unit. 
     
     
         6 . The propulsion system of  claim 1 , wherein the support face comprises a rigid, semi-rigid or an elastic material or a combination thereof. 
     
     
         7 . The propulsion system of  claim 1 , wherein a support element is arranged at the support face, the support element is made of a rigid, semi-rigid or an elastic material or a combination thereof. 
     
     
         8 . The propulsion system of  claim 1 , wherein the drive unit is pivoted between the lowered position and the raised position by a tilt arrangement. 
     
     
         9 . The propulsion system of  claim 2 , wherein the drive unit is connected with the transom bracket via a connecting arm, the connecting arm being connected with the transom bracket via the first pivot joint and connected with the drive unit via a second pivot joint, wherein the drive unit is configured to be moved in the water and out of the water by the connecting arm pivots around the first pivot joint or the drive unit pivots around the second pivot joint or the connecting arm and the drive unit pivot around both pivot joints. 
     
     
         10 . The propulsion system of  claim 9 , wherein the connecting arm comprises an arm support member, the arm support member is arranged opposite the support face in the lowered position of the drive unit whereby the support face is configured to support the arm support member in different angles of the drive unit. 
     
     
         11 . The propulsion system of  claim 9 , wherein the connecting arm is configured to be pivoted around the first pivot joint in a clockwise direction or an anticlockwise direction independently of any pivoting of the drive unit around the second pivot joint. 
     
     
         12 . The propulsion system of  claim 9 , wherein the drive unit is configured to be pivoted around the second pivot joint in a clockwise direction or an anticlockwise direction independently of any pivoting of the connecting arm around the first pivot joint. 
     
     
         13 . The propulsion system of  claim 9 , wherein the connecting arm is configured to be pivoted around the first pivot joint in a clockwise direction or an anticlockwise direction at the same time as the drive unit is pivoted around the second pivot joint in a clockwise direction or an anticlockwise direction. 
     
     
         14 . The propulsion system of  claim 9 , wherein the first pivot joint is arranged at a first end of the connecting arm, the second pivot joint is connected at a second end of the connecting arm. 
     
     
         15 . The propulsion system of  claim 14 , wherein the arm support member is arranged at the second end. 
     
     
         16 . The propulsion system of  claim 1 , wherein the support face has a first side and a second side, the first side and/or the second side has a side support face projecting outwards from the support face so that the side support face can support the support member in a transverse direction in relation to a longitudinal extension of the marine vessel. 
     
     
         17 . The propulsion system of  claim 16 , wherein a first support face is projecting outwards from the first side and a second support face is projecting outwards from the second side. 
     
     
         18 . The propulsion system of  claim 1 , wherein the drive unit comprises an electric motor. 
     
     
         19 . The propulsion system of  claim 2 , wherein the drive unit is configured to be trimmed and/or titled around the first pivot joint and/or the second pivot joint.
