Abstract: The present invention relates to a mounting device (30) for a joystick (10), the mounting device (30) comprising a first and second mounting element (32, 34), a spring element (36) and a ball element (38). The two mounting elements (32, 34) are rotatably attached to allow rotation of the joystick (10) about a central axis (22) of yaw rotation. The spring element (36) is mounted to the first mounting element (32) and urges the ball element (38) against a ball support surface (50) of the second mounting element (34). The ball support surface (50) is inclined such that rotation of the stick element (16) about the central axis (22) away from a neutral yaw position causes increase of tension in the spring element (36), biasing the joystick (10) towards the neutral yaw position. Further, the invention relates to a joystick (10) and a marine vessel.

Abstract: The present invention relates to a mounting device (30) for a lever (10) configured for controlling a marine vessel. The mounting device (30) is configured to hold a lever element (14) rotatably about a rotation axis (32) and to adjust an amount of resistance against moving the lever element (14) depending on an angular lever position. In a first angular lever position range, the amount of resistance against further angular deflection increases with an increased deflection of the lever element (14) beyond a neutral position. The present invention further relates to a lever (10) configured for controlling a marine vessel and to a marine vessel.

Abstract: A boat drive including combustion engine located within the hull and a drive unit located outside the hull. The drive has a propeller shaft and an exhaust system with an exhaust duct and an outlet. The exhaust duct connects the engine to the exhaust outlet for carrying away exhaust gases from the engine and cooling water introduced into the exhaust duct. The exhaust outlet is arranged in the propeller shaft. A first exhaust release opening is arranged in the exhaust duct, between the engine and the exhaust outlet, so that during operation, a first fraction of the exhaust gases and cooling water is discharged through the first exhaust release opening, while a second fraction of the exhaust gases and the cooling water is discharged through the exhaust outlet. A device is provided for adjusting the first fraction that can be discharged through the first exhaust release opening.
