PROPULSION CONTROL ARRANGEMENT FOR A MARINE VESSEL
A propulsion control arrangement operable to control a speed and possible direction of a marine vessel. A marine propulsion control system controlling a carried by a hull of a marine vessel, wherein the marine propulsion control system is adapted to receive an input command from the propulsion control arrangement.
Shift interrupt method for a marine propulsion system
A system and method of interrupting power to an ignition coil in a marine engine during an actuation of a shift cable for transitioning between gears is provided. The method includes connecting a sensor assembly to the shift cable. The sensor assembly includes magnets, a Hall sensor for magnetic sensing, and a control circuit. The magnets are configured to pass by the Hall sensor, which senses a change in polarity of the magnets. The control circuit is configured to interrupt power to the ignition coil. The method includes sensing a polarity of the magnets; determining if the polarity of the magnets has changed; and sending a signal to the control circuit based on the change in polarity of the magnets, which causes an output interrupting power to the ignition coil.
MULTI-SPEED TRANSMISSIONS AND METHODS FOR SHIFTING MULTI-SPEED TRANSMISSIONS FOR MARINE VESSELS
A method for shifting a multi-speed transmission for transmitting rotation between an input shaft and an output shaft for a marine vessel. The method includes providing a multi-speed transmission having first and second gears engaged by actuating first and second clutches, and providing first and second pressure sensors that measure first and second pressures within the first and second clutches, respectively. The method further includes performing a first shift from the first gear to the second gear by de-actuating the first clutch a first delay after the second clutch is actuated, then measuring the first and second pressures and determining a first shift pressure at which the first and second pressures are substantially equal while performing the first shift. The method further includes comparing the first shift pressure to a first pressure threshold range and adjusting the first delay when the first shift pressure is outside the first pressure threshold range.
SYSTEMS AND METHODS FOR SHIFTING MULTI-SPEED TRANSMISSIONS
A method for shifting a marine propulsion device transmission between first and second gears transmitting torque from a powerhead with a redline RPM. The transmission has a transition time for completing a shift. The method includes measuring an RPM of the powerhead, comparing the RPM to a first threshold, and starting a timer when the RPM exceeds the first threshold. The method includes measuring the RPM of the powerhead after the first threshold is exceeded, comparing the RPM to a second threshold, stopping the timer when the RPM exceeds the second threshold, determining an elapsed time between starting and stopping the timer, and determining a shift RPM based on the determined elapsed time, the redline RPM, and the transition time of the transmission. The method includes controlling the transmission to shift when the RPM measured for the powerhead reaches the shift RPM such that shifting completes before the redline RPM.
SYSTEMS AND METHODS FOR SHIFTING MULTI-SPEED TRANSMISSIONS
A method for shifting a multi-speed transmission of a marine propulsion device between a first gear and a second gear each configured to transmit torque from a powerhead to a transmission output shaft. The method includes determining an actual power level requested for operating the marine propulsion device and measuring a transmission output shaft speed in which the transmission output shaft is rotating. The method further includes comparing the actual power level to a shift threshold, the shift threshold corresponding to expected power levels for operating the marine propulsion device as a function of the transmission output shaft speed of the transmission output shaft. The method further includes controlling the multi-speed transmission to shift when the actual power is outside the shift threshold.
SYSTEMS AND METHODS FOR SHIFTING MULTI-SPEED TRANSMISSIONS
A method for downshifting a multi-speed transmission of a marine propulsion device to a first gear from a second gear. The method includes providing a shift schedule that indicates a shift recommendation for when to downshift from the second gear to the first gear. The method further includes configuring the transmission to downshift when the shift schedule indicates the shift recommendation, determining a requested speed of the marine propulsion device, measuring an actual speed of the marine propulsion device, calculating an error between the requested speed and the actual speed, comparing the error to an error threshold, and determining when the error exceeds the error threshold longer than a duration threshold. The method further includes controlling the transmission to downshift, despite the shift schedule indicating a non-shift recommendation, when the duration threshold is exceeded so as to reduce the error between the requested speed and the actual speed.
OPERATION DEVICE FOR SHIP PROPULSION MACHINE
An operation device includes a lever, a holder rotatably supporting the lever, a rotation restriction mechanism restricting a rotation range of the lever to the rotation range including a forward movement operation range, a backward movement operation range, and a neutral position, and a lever holding mechanism holding the lever at the neutral position. The lever includes a base portion rotatable supported by the holder, and an operation portion being movably connected to the base portion with respect to the base portion in an extending direction of the operation portion. The lever holding mechanism holds the lever at the neutral position so as not to be rotatable when the operation portion moves toward one side in the extending direction, and brings the lever into a rotatable state from the neutral position when the operation portion moves toward the other side in the extending direction.
PERSONAL WATERCRAFT
A hybrid personal watercraft combines features of pontoon boats and deck boats, in a cost-effective and versatile package. The watercraft includes port and starboard sponsons which combine a pair of outboard flotation cavities. A space below the deck and above the hull bottom creates at least one, and potentially up to three additional flotation cavities, which may also be used as storage areas accessible by an access door in the bow of the watercraft and/or a set of hatches in the deck. The watercraft may be efficiently produced assembled from polymer materials, such as thermoplastic polyolefin (TPO).
VESSEL OPERATION SYSTEM AND VESSEL
A vessel operation system includes a propulsion apparatus to generate a forward thrust or a backward thrust by output of an engine, a throttle actuator to change a throttle opening degree of the engine, a first operator, a second operator, and a controller. When the propulsion apparatus generates a backward thrust, the controller sets a first target value within a range not more than a first upper limit value in accordance with an operation of the first operator and control the throttle actuator so that the throttle opening degree reaches the first target value. The controller sets a second target value within a range not more than a second upper limit value larger than the first upper limit value in accordance with an operation of the second operator and control the throttle actuator so that the throttle opening degree reaches the second target value.
BOAT SIDE CONSOLE
A modular steering console. The modular steering console has a main console portion having a top side and a side. The top side includes holes for receiving bolts. The side of the main console portion has holes for receiving bolts. The modular steering console has one or more brackets having slots in a top side configured to be fastened to the main console top side by bolts through the slots to allow lateral adjustment of the brackets while allowing a side of the brackets and the side of the main console portion to sandwich a side of a boat.
