A marine propulsion system includes an engine-powered propulsion device coupled in torque-transmitting relationship with an engine. A non-engine-powered propulsion device is coupled to a source of electric or hydraulic power. A control module is provided in signal communication with the engine-powered propulsion device and the non-engine-powered propulsion device. A user-operated input device is in signal communication with the control module. The marine propulsion system operates in a non-engine-powered propulsion mode in response to the control module determining the following: the engine was previously running; a speed of the engine is below an engine-stopped speed threshold; the marine propulsion system is on; and a request for movement of the vessel has been input via the user-operated input device. While the marine propulsion system operates in the non-engine-powered propulsion mode, the control module controls the non-engine-powered propulsion device to generate thrust to maneuver the vessel according to the request for movement.

A watercraft has a deck; central, left and right pods connected to a bottom of the deck; and a helm assembly disposed on the deck. The central pod is laterally centered relative to the deck. The central pod has a central hull defining a central tunnel, a motor connected to and disposed at least in part in the central hull, and a jet propulsion system disposed at least in part in the tunnel and operatively connected to the motor. The left pod is disposed at a left of the central pod and is laterally spaced from the central pod. The left pod has a left hull that is narrower than the central hull. The right pod is disposed at a right of the central pod and is laterally spaced from the central pod. The right pod has a right hull that is narrower than the central hull.

A trim system for a watercraft has a nozzle pivotable about a trim axis, a trim actuator operatively connected to the nozzle, at least one sensor for sensing at least one operating condition of the watercraft, a control unit electronically connected to the at least one sensor for receiving a sensor input signal indicative of the at least one operating condition. In a first trim control mode, the control unit controls the trim actuator to pivot the nozzle about the trim axis within a first range of trim angles. In a second trim control mode, the control unit controls the trim actuator to pivot the nozzle about the trim axis within a second range of trim angles. The first range of trim angles is greater than the second range of trim angles. A watercraft having a trim system and a method of controlling the trim are also disclosed.
