| 20080280512 | Jet-Propulsion Personal Watercraft - A jet-propulsion personal watercraft includes an engine configured to generate a driving power for generating a propulsion force to propel the watercraft, an engine speed changing system configured to be able to change an engine speed of the engine, a determiner configured to determine whether or not to execute control for effectively steering the watercraft at start of deceleration, and an engine controller configured to control the engine speed changing system based on information received from the determiner. The engine controller is configured to, when the determiner determines that the control for effectively steering the watercraft should not be executed, control the engine speed changing system so that a decrease rate of the engine speed immediately after the determination is smaller than a decrease rate of the engine speed in a case where the determiner determines that the control for effectively steering the watercraft should not be executed. | 11-13-2008 |
| 20100082214 | Driving Control System for Personal Watercraft - A driving control system includes a controller which is configured to, in response to a command for starting an auto-cruise mode generated by the operation of an input device, control an engine speed or a vehicle speed so that a value detected by a speed detector falls within a cruising speed range, when the value detected by the speed detector is outside the cruising speed range; and to then cause the watercraft to cruise at a constant engine speed or at a constant vehicle speed. | 04-01-2010 |
| 20100131131 | Personal Watercraft - A personal watercraft includes a handle having a pair of right and left grip portions, and a handle pad configured to cover a region of the handle, the region being located between the pair of grip portions. The handle pad is provided on a surface thereof with an accommodating concave portion configured to accommodate therein a portable information device. | 05-27-2010 |
| 20100167607 | Personal Watercraft - A personal watercraft comprises an engine which is mounted in a body of the watercraft and is equipped with an open-loop water cooling system; a coolant passage in which water for cooling the engine flows; a water flow generator configured to operate in association with the engine to generate a water flow in the coolant passage; and a valve unit configured to restrict a flow of the water in the coolant passage. | 07-01-2010 |
| 20110159753 | PERSONAL WATERCRAFT - A personal watercraft comprises an oil cooler including an oil cooling passage through which oil circulating inside an engine flows and a coolant passage through which coolant for cooling the oil in the oil cooling passage flows; a first oil passage through which the oil flowing toward the oil cooling passage flows; a second oil passage through which the oil flowing out from the oil cooling passage flows; a bypass passage connecting the first oil passage to the second oil passage so as to bypass the oil cooling passage; and a valve configured to open and close the bypass passage; wherein the valve opens the bypass passage when the temperature of the oil is lower than a predetermined value and closes the bypass passage when the temperature of the oil is not lower than the predetermined value. | 06-30-2011 |
