Trim system for a watercraft and method for controlling a trim of a watercraft

A trim system for a watercraft comprising:

• a nozzle adapted for being pivotally connected about a trim axis;
• a trim actuator operatively connected to the nozzle for pivoting the nozzle about the trim axis;
• at least one sensor for sensing at least one operating condition of the watercraft, the at least one operating condition of the watercraft being at least one of watercraft speed, motor speed, motor speed input device position, water pressure in a jet propulsion system of the watercraft, and water flow speed in the jet propulsion system;
• a control unit electronically connected to the at least one sensor for receiving a sensor input signal from the at least one sensor and to the trim actuator for controlling the trim actuator, the sensor input signal being indicative of the at least one operating condition,
• the control unit controlling the trim actuator to pivot the nozzle about the trim axis in a selected one of at least a first trim control mode and a second trim control mode,
• in the first trim control mode, the control unit controlling the trim actuator to pivot the nozzle about the trim axis within a first range of trim angles,
• in the second trim control mode, the control unit controlling the trim actuator to pivot the nozzle about the trim axis within a second range of trim angles,
• the first range of trim angles being greater than the second range of trim angles,
• the control unit controlling the trim actuator in the first trim control mode when the at least one operating condition is below a threshold value of the at least one operating condition until the at least one operating condition exceeds the threshold value,
• the control unit controlling the trim actuator in the second trim control mode when the at least one operating condition is above the threshold value of the at least one operating condition.

A method for controlling a trim of a watercraft comprising:

• sensing at least one operating condition of the watercraft, the at least one operating condition of the watercraft being at least one of watercraft speed, motor speed, motor speed input device position, water pressure in a jet propulsion system of the watercraft, and water flow speed in the jet propulsion system;
• controlling a trim actuator to pivot a nozzle of a jet propulsion system of the watercraft about a trim axis in a first trim control mode when the at least one operating condition is below a threshold value of the at least one operating condition until the at least one operating condition exceeds the threshold value;
• and
• controlling the trim actuator to pivot the nozzle about the trim axis in the second trim control mode when the at least one operating condition is above the threshold value of the at least one operating condition,
• in the first trim control mode, the trim actuator is controlled to pivot the nozzle about the trim axis within a first range of trim angles,
• in the second trim control mode, the trim actuator is controlled to pivot the nozzle about the trim axis within a second range of trim angles, and
• the first range of trim angles being greater than the second range of trim angles.
