An outdrive for a marine vessel, such as a watercraft having an inboard engine, is provided. The outdrive can include a standoff box joined with a drive unit having a driveshaft that rotates in response to rotation of an input shaft coupled to an engine within a hull of the watercraft. The drive unit includes a propeller shaft that rotates in response to rotation of the driveshaft, and an associated propeller. The drive unit is vertically movable from a raised mode to a lowered mode, in which the propeller shaft is a preselected distance from a bottom of the boat hull, thereby lowering a thrust point produced by the propeller, all while the watercraft is moving through water and while the propeller is producing thrust. A related method and standoff box are also provided.

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.

An outboard propulsion system comprising an engine configured to receive oil; an oil pan configured to receive oil from the engine; and an oil reservoir configured to receive oil from the oil pan and provide oil to the engine, in use.
