Abstract
An operation device for a water-jet propulsion watercraft includes a first rotational shaft and a second rotational shaft. A first link can be rotatable about the first rotational shaft and a second link can be rotatable about the second rotational shaft. A bridging link can be configured to be capable of moving in parallel. A rotational end of the first link and a rotational end of the second link can be coupled such that an imaginary straight line connecting the rotational end to the first rotational shaft is parallel to an imaginary straight line connecting the rotational end to the second rotational shaft. A holding section can be provided on the bridging link to be held and operated by an operator.
Claims14
An operation device for a water-jet propulsion watercraft comprising:
- a first and a second rotational shaft provided parallel to each other in a hull of the watercraft;
- a first link rotatable about the first rotational shaft and a second link rotatable about the second rotational shaft;
- a bridging link with a rotational end of the first link and a rotational end of the second link being coupled such that an imaginary straight line connecting the rotational end of the first link to the first rotational shaft is parallel to an imaginary straight line connecting the rotational end of the second link to the second rotational shaft, the bridging link having at least an operator's seat side end and a portion near the operator's seat side end extending approximately parallel to an imaginary straight line connecting the rotational ends and capable of moving in parallel;
- and
- a holding section provided on the bridging link to be held and operated by an operator of the watercraft;
- wherein a reciprocating movement of the holding section is transmitted to an engine output control device or a propelling direction changing device through the bridging link, the first link, and the second link.
An operation device for a water-jet propulsion watercraft comprising:
- an engine driving a jet pump;
- an output control device configured to control an output of the engine;
- a reverse bucket disposed on the jet pump;
- a user operable handle disposed in the hull and configured to allow the user to input control commands to at least one of the output control device and the reverse bucket;
- and
- means for guiding the handle through a generally linear movement.
