Abstract

A method of controlling a propeller drive assembly attachable to a hull of a marine vessel, said propeller drive assembly comprising a propeller drive unit and a housing for attachment to a hull of the marine vessel on an inside of the hull. The housing defines an inner space and an opening through which at least a portion of the propeller drive unit is movable into and out of the inner space. The propeller drive assembly comprises a suspension mechanism attached to the housing and configured to suspend the propeller drive unit, wherein the suspension mechanism is adapted to move the propeller drive unit between a stowed position and a deployed position. The method comprises a first step comprising triggering rotation of each propeller shaft such that the respective propeller shaft reaches a respective predetermined rotational position and stops at the respective predetermined rotational position, and a second step comprising triggering movement of the suspension mechanism from the deployed position to the stowed position. Each propeller shaft is provided with a respective propeller, and wherein the respective predetermined position of each propeller shaft is such that each respective propeller is at least partly confined within the inner space of the housing when the propeller drive unit is in the stowed position.
