A sharpener assembly for a food slicer includes a rotatable frame with a sharpening member and a truing member operatively connected for rotation with the frame. The frame is mounted on a food slicer to place the sharpening member and truing member on opposed sides of a slicer knife. The frame is rotated to rotate the sharpening member and the truing member into contact with respective sides of the slicer knife.

The watercraft of claim 1, wherein the first sensor is a watercraft speed sensor configured to output a signal to the controller that is indicative of a vehicle speed of the watercraft. 7. The watercrafi of claim 1, wherein the first sensor is a throttle valve position sensor configured to output a signal to the controller that is indicative of the position of the throttle valve. 8. The watercraft of claim 1, wherein throttle valve control mechanism is configured to maintain the throttle valve open to a degree corresponding to a trolling condition of the watercraft. 9. The watercraft of claim 1, wherein throttle valve control mechanism is configured to maintain the throttle valve open to a degree corresponding to a transient condition of the watercraft between a displacement mode of operation and a planing mode of operation. 10. The watercraft of claim 1, wherein the engine control system additionally comprises a steering angle sensor, and wherein the controller is configured to deactivate the throttle valve control mechanism so as to permit the throttle valve to return to an idle position when a steering angle is less than a preset degree. 11. The watercraft of claim 1, wherein the controller and the throttle valve control mechanism are configured to maintain the throttle valve at a preset position between the idle and fully open positions. 12. The watercraft of claim 1, wherein the controller and the throttle valve control mechanism are configured to retard movement of the throttle valve from a preset position, which lies between the idle and fully open positions, to the idle position. 13. The watercraft of claim 12, wherein the controller and the throttle valve control mechanism are configured to gradually decrease the opening degree of the throttle valve at least over a range of movement between the preset position and the idle position. 14. A jet propelled watercraft comprising: an engine having at least one throttle valve, the throttle valve being movable between a closed position and a fully open position; a throttle operator remotely positioned relative to the engine and coupled to the throttle valve, the throttle operator being movable between first and second positions whereby the throttle operator causes the throttle valve to move between the closed and fully open positions, respectively; a steering mast comprising a handlebar rotatably carried by the steering mast and configured to steer the watercraft; and an engine control system comprising a first sensor configured to detect an operating state of the watercraft or the engine, a second sensor configured to detect a position of the throttle operator, a third sensor configured to detect an angular orientation of the handlebar, a throttle valve control mechanism including an actuator cooperating with the throttle valve under at least one operating state of the watercraft or the engine, and a controller communicating with the first and second sensors and with the throttle valve control mechanism, the controller being configured to activate the throttle valve control mechanism once the operating state of the watercraft or engine is greater than a predetermined state, and the controller and throttle valve control mechanism further being configured to delay closure of the throttle valve at least when the throttle operator moves to the first position and the handlebar exceeds a predetermined angular orientation, wherein the first sensor is an engine speed sensor configured to output a signal to the controller that is indicative of engine rotational speed. 15. A jet propelled watercraft comprising: an engine having at least one throttle valve, the throttle valve being movable between a closed position and a fully open position; a throttle operator remotely positioned relative to the engine and coupled to the throttle valve, the throttle operator being movable between first and sec
