Abstract: A marine motor assembly for mounting to a watercraft is disclosed. The marine motor assembly has a motor unit including a motor unit housing, a motor, a propulsion device, an air pump fluidly communicating with an under-housing volume of the motor unit housing, a pressure sensor for measuring air pressure in the under-housing volume, and a control unit communicating with the air pump and the pressure sensor. The control unit is programmed for controlling the air pump for changing air pressure in the under-housing volume, and monitoring change in the air pressure for a predetermined amount of time for confirming that the motor unit housing is water-resistant, or that the water resistance of the motor unit housing is compromised. A method for testing a water resistance of a motor unit housing of a marine motor assembly is also disclosed.
