A method is provided for controlling a boat. The boat is adapted to float in a body of water. The boat includes a hull having a longitudinal extension along a hull longitudinal axis, a lateral extension along a hull lateral axis and a vertical extension along a hull vertical axis. The boat also includes a set of drive units, the set of drive units comprising at least one drive unit. Each drive unit in the set is arranged such that it, during driving of the boat, is adapted to be at least partially submerged into the body of water; adapted to be pivotable, relative to the hull, around a drive unit longitudinal axis that is substantially parallel to the hull longitudinal axis such that a drive unit roll angle can be varied, and adapted to be pivotable, relative to the hull, around a steering axis that forms an angle with the drive unit longitudinal, axis such that a drive unit steering angle can be varied.

A transport package for a boat propeller drive () that has a suspension fork () for suspending the drive in a suspension plate mounted on the stern transom of a boat. The package includes a bottom plate () and a cover that can be removed from the bottom plate. The drive is held in a fixed position in the package by means of upper and lower spacing elements (). When the cover and the upper spacing elements are removed, the suspension fork is exposed and the drive is held stable in an upright position by the bottom plate together with the lower spacing elements to serve as a mounting fixture.

Apparatus for adapting a propeller system including a propeller shaft () and a propeller () adapted to be mounted on the propeller shaft (). The propeller system includes a propeller () connected in a rotationally fixed manner to a propeller shaft (), the propeller shaft () having a portion provided with splines () which cooperate with corresponding splines () inside the hub () of the propeller () in order to obtain the rotationally fixed connection, where the splines () on the propeller shaft () and in the hub () of the propeller () are helical, with a predetermined oblique angle (&#x3b1;, &#x3b2;). The invention also relates to a propeller shaft () and a propeller () which are intended to be used in the propeller system.

Method and device for regulating the phase angle between a first and a second crankshaft of an internal combustion engine. The engine includes primary cylinders that communicate with secondary cylinders and in every primary cylinder there is movably arranged a primary piston that is connected to the first crankshaft and in every secondary cylinder there is movably arranged a secondary piston that is connected to the second crankshaft. The first and second crankshafts are connected to each other by means of a transmission adapted with the device that includes a crankshaft extension for obtaining the control of the phase angle, the extension being fixed against rotation and displaceably connected to one of the crankshafts and via a grooved portion rotationally connected to the second of the crankshafts. When the crankshaft extension in displaced, rotation is obtained in the grooved portion that results in a corresponding phase angle shift.
