A method of controlling a watercraft comprises actuating a lever, controlling a speed of rotation of an engine to be at or below a reverse gate actuation speed in response to the actuation of the lever, moving the reverse gate in response to the actuation of the lever without further driver intervention once the speed of rotation of the engine is at or below the reverse gate actuation speed, and controlling the speed of rotation of the engine in order to decelerate the watercraft in response to the actuation of the lever and the reverse gate moving without further driver intervention. A watercraft and a method of controlling the watercraft based at least in part on an angle of a helm assembly are also disclosed.

What is claimed is: 1. A method of controlling a watercraft, the watercraft having a hull, a deck disposed on the hull, a seat disposed on the deck, an engine compartment defined between the hull and the deck, an engine disposed in the engine compartment, an electronic control unit, a jet propulsion system connected to the hull and operatively connected to the engine, a throttle operator for controlling the engine, a lever, and a reverse gate operatively connected to the hull, the reverse gate being movable between a first stowed position and a second position in which the reverse gate redirects a jet of water expelled from the jet propulsion system, the reverse gate being in operative connection with the lever, the method comprising: actuating the lever; determining a speed of rotation of the engine; if the speed of rotation of the engine is above a predetermined reverse gate actuation speed: controlling the speed of rotation of the engine to be at or below the reverse gate actuation speed in response to the actuation of the lever; and moving the reverse gate to the second position in response to the actuation of the lever without further driver intervention once the speed of rotation of the engine is at or below the reverse gate actuation speed; if the speed of rotation of the engine is at or below the predetermined reverse gate actuation speed: moving the reverse gate to the second position in response to the actuation of the lever without further driver intervention; and controlling the speed of rotation of the engine in order to decelerate the watercraft in response to the actuation of the lever and the reverse gate moving to the second position without further driver intervention. 2. The method of claim 1, wherein controlling a speed of rotation of the engine in order to decelerate the watercraft includes increasing the speed of rotation of the engine above the reverse gate actuation speed. 3. The method of claim 1, further comprising adjusting the second position of the reverse gate without further driver intervention. 4. The method of claim 1, wherein controlling the speed of rotation of the engine comprises adjusting a position of a throttle valve of the engine. 5. The method of claim 1, wherein controlling the speed of rotation of the engine comprises adjusting at least one of an ignition timing and an injection timing of the engine. 6. The method of claim 1, further comprising: sensing a position of the throttle operator; adjusting a position of a throttle valve of the engine based on the position of the throttle operator when the lever is not actuated; generating a signal when the lever is actuated; and adjusting the position of the throttle valve of the engine based on the signal when the lever is actuated. 7. The method of claim 1, further comprising: sensing a speed of the watercraft; and moving the reverse gate to a neutral position in which the reverse gate redirects a jet of water expelled from the jet propulsion system so as to maintain the watercraft in position when the speed of the watercraft is near or at zero without further driver intervention. 8. A watercraft comprising: a hull; a deck disposed on the hull; an engine compartment defined between the hull and the deck; an engine disposed in the engine compartment; a throttle body having a throttle valve and being in fluid communication with the engine; a jet propulsion system connected to the hull and operatively connected to the engine; an electronic control unit (ECU) associated with the watercraft for controlling at least an operation of the engine; a throttle operator being movable between an idle position and an actuated position and being in electronic communication with the ECU; a throttle valve actuator operatively connected to the throttle valve and in electronic communication with the ECU; an engine speed sensor for sensing a rotational speed of the engine and being in electronic communication with the ECU; a reverse gate operatively connected to the hull, the reverse gate being movable between a first stowed position and a second position in which the reverse gate redirects a jet of water expelled from the jet propulsion system; a reverse gate actuator operatively connected to the reverse gate for moving the reverse gate between the first stowed position and the second position, and being in electronic communication with the ECU; and a lever associated with the watercraft and being in electronic communication with the ECU, wherein when the engine speed sensor senses a speed of rotation of the engine above a predetermined reverse gate actuation speed, the ECU sends a first signal to the throttle valve actuator in response to an actuation of the lever such that a speed of rotation of the engine is controlled to be at or below the reverse gate actuation speed, the ECU sends a second signal to the reverse gate actuator to move the reverse gate to the second position in response to the actuation of the lever once the speed of rotation of the engine is at or below the reverse gate actuation speed; wherein when the engine speed sensor senses a speed of rotation of the engine at or below the predetermined reverse gate actuation speed, the ECU sends the second signal to the reverse gate actuator to move the reverse gate to the second position in response to the actuation of the lever; and wherein the ECU sends a third signal to the throttle valve actuator in response to the actuation of the lever such that actuating the lever results in a controlled deceleration of the watercraft once the reverse gate is in the second position. 9. The watercraft of claim 8, further comprising a handlebar; wherein the throttle operator is disposed on the handlebar; and wherein the throttle operator is selected from a group consisting of a thumb-actuated throttle lever, a finger-actuated throttle lever, and a twist grip. 10.
