    Another likely lost sale due to the Kawasaki CEO and corporate team still not addressing this significant issue that they definitely must know all about.

    If you can test ride an Ultra 310 and it works well at all throttle and speed conditions, then I think you are fine as this issue seems to be fairly binary; it won't come out of nowhere, it either happens or it doesn't. I got lucky on my 2017 model as I did not test ride, but in no way would I buy a new one now until they acknowledge the problem and deal with it properly.

    The engine and the rest of the machine seems to be reliable outside of this part throttle problem, which makes it all the more ridiculous that spineless corporate yespeople keep looking the other way.

    This is the best info I have found. Is long reading but good info.

    Marine 1,498 cm3 4-Stroke In-Line Four Engine
    Fitted with a supercharger and intercooler, the liquid-cooled 1,498
    cm3, In-line 4-cylinder marine engine that propels the ULTRA 310
    Series models forward with an exhilarating rush of acceleration
    produces an output much greater than a normally aspirated engine
    of the same displacement. This is due in large part to the use of a
    roots type TVS supercharger, which generates boost even at low
    rpm to ensure powerful acceleration, right from idle. Maximum
    output is a lofty 228 kW (310 PS)*.
    *Output measured at the crankshaft under controlled conditions. Actual performance may vary.
    * DOHC, 16-valve, fuel-injected, 4-stroke In-Line Four engine displaces
    1,498 cm3 and has a bore/stroke ratio of 83.0 x 69.2 mm. Compression
    is 8.2:1.
    * A single throttle body is used with a bore diameter of ø60 mm.
    * High-flow fuel injectors with 4 orifices complement the engine’s
    substantial output and contribute to combustion efficiency.
    * For efficient piston cooling, each piston is cooled by two oil jets with
    0.5 mm jet nozzles.
    * Water jacket distributes water evenly around the cylinder for efficient
    cooling performance. To help prevent dilution due to over-cooling, a
    check-valve opens to release the water from the jacket when the engine
    is idling or turned off; it closes when running to allow the jacket to fill.
    * Oil cooler features a second water-cooling layer to ensure adequate
    cooling at higher rpm.

    * Baffle plates (2 longitudinal, 1 cross) in the oil pan act as partitions,
    helping to keep oil from collecting on one side of the pan during tight
    turns, or sudden acceleration/deceleration.
    * The ULTRA 310 Series models feature a 4-into-2-into-1 powerboat-style
    exhaust system, which routes the exhaust pipe upwards. This allows
    the smoothest flow for exhaust gases, maximising exhaust efficiency.
    * Dual water muffler arrangement provides greater volume, which reduces
    exhaust back pressure, and in turn contributes to performance. The
    large muffler volume also contributes to a quite ride.
    Supercharger and Intercooler
    * The roots type supercharger is known as a fixed displacement
    supercharger. This design produces large amounts of boost even at
    low rpm, for instant and powerful acceleration right off of idle. With
    every revolution, it force-feeds the engine 2 litres of air (theoretical
    volume is 2,019.3 cm3 per engine revolution), ensuring a stable supply
    of high-pressure intake air at all rpm. The result is a very flat and meaty
    torque curve and step-free power across the rev range, with none of the
    time lag associated with turbochargers.
    * Twin Vortices Series (TVS) Roots supercharger, featuring twin 4-lobe
    rotors, is highly efficient and quite compact. Boost pressure is 16.8 psi.
    * Where some superchargers deliver compressed air in waves, the TVS
    unit offers continuous delivery, contributing to smooth throttle response.
    * Internal planetary gearing increases supercharger speed 2.1 times,
    to ensure the necessary speed to deliver the high-power output. An
    external pulley has a 0.9 reduction ratio. The combination delivers the
    required rotational speed while ensuring a low belt load.

    * To ensure ideal intake air pressure, not one, but two air bypass valves
    are used. A vacuum air bypass valve is used to balance air pressure
    upstream and downstream of the throttle body. It works mostly at
    low and medium rpm. A second, regulatory air bypass valve aids the
    vacuum air bypass valve in preventing over-boosting when the throttle
    is shut (or opened) suddenly. Should the system’s specified maximum
    pressure be exceeded, the regulatory air bypass valve is activated,
    allowing air to escape.
    * Efficiently cooling the high-pressure intake air is a liquid-cooled
    intercooler. Friction between the air molecules heats the intake air to
    extremely high (power-robbing) temperatures, but the intercooler cools
    the air back down to ambient temperature. Cooler air results in high
    engine output.

    Electronic Throttle Valve
    Electronic throttle valves efficiently manage the engine’s massive
    power output. They also make minute engine control possible,
    enabling easy switching between riding modes.
    * Accelerator Position Sensor (APS) converts throttle lever input to an
    electronic signal. This signal is then used by the ECU to control the
    throttle valve via electric motor. A Throttle Position Sensor (TPS) on the
    throttle body provides feedback to the ECU.
    * Redundancy in the system (APS and TPS each send two sets of signals
    to the ECU) ensures some control is maintained in case of failure.

    Propulsion (Jet Pump / Impeller)
    Electric Trim-Control System
    * To efficiently convert the ULTRA 310 Series engine’s massive power
    into thrust, a large-diameter ø160 mm jet pump is used.

    * Developed based on feedback from Kawasaki’s race machines, this
    pump was specially designed to deliver breathtaking acceleration,
    stable output and good “bite,” even when riding in rough water.
    * A large impeller, featuring a sophisticated 3-blade design, delivers both
    high performance and quiet operation. A revised impeller blade angle
    contributes to increased acceleration performance off the line.
    * 8-vane guide smooths and regulates the flow of water from the impeller
    for efficient and powerful propulsion.
    * Horizontal guide vanes on the grate “grip” the water, keeping the bow
    from rising on acceleration for improved stability. The improved hookup
    enables a more efficient transfer of power to thrust.
    * ø88 mm steering nozzle, designed to be short and slim, ensures a light
    steering load. Handling feels light despite the high-power output.

    Electric Trim-Control System
    * This convenient system allows the angle of the jet pump nozzle to be
    controlled electrically (seven positions: STD +/- three positions), making
    it easier for riders to adjust the attitude of the hull to suit water surface
    conditions and riding style.
    * In rough water, angling the jet pump upwards raises the bow for rough
    water handling. Conversely, when conditions are smooth, angling the
    jet pump downwards lowers the bow for turning performance.

    Launch Control Mode - NEW
    When accelerating with the system engaged, the trim is
    automatically adjusted to suit vehicle speed.

    * Two modes allow either single or repeated launches.
    - Single mode: once set, Launch Control Mode is only active for the first
    acceleration period.
    - Repeat mode: once set, Launch Control Mode is active each time the
    rider accelerates from a slow speed.

    Electronic Cruise Control
    This mode fixes speed (rpm) at the level specified. It is a
    convenient feature for long-distance cruising.

    * The mode is activated by pushing the button on the right handle
    when riding.
    * Cruising speed can be adjusted using the UP and DOWN buttons.
    * During operation, the speed displayed on instrument panel will
    flash slowly.
    * After activation, the throttle is pulled all the way in to maintain speed.
    (This position is more relaxing than keeping the lever at partial
    throttle.) Releasing the throttle lever disengages the system.

    One-Touch "NO WAKE" Mode - NEW
    This handy mode is used in “No Wake” zones. It regulates engine
    speed to maintain a forward speed of 5 mph (8 km/h).

    * When activated, the drive mode indicator will read “5mph.”
    * When riding into a headwind or with a load, pushing the cruise control
    UP button offers three levels of increased rpm. Speed range is 5 mph (8
    km/h) to 6.2 mph (10 km/h). NEW
    * To disengage, press the button again, or pull the throttle lever.

    Power Mode Selection / SLO-Mode - NEW

    Riders can select from Full, Middle and Low Power Operation, as
    well as Smart Learning Operation (SLO)-Mode.

    * When using the standard (Full Power Operation) key, riders can easily
    switch between power modes to suit conditions, skill level, or preference
    using the mode button on the left handle.
    * With Full Power Operation (FPO), engine output is unrestricted, allowing
    riders to experience the unbridled potential of the supercharged engine.
    * Middle Power Operation (MPO) and Low Power Operation (LPO) offer
    progressively more restricted engine output. MPO limits output to
    approximately 80% of FPO; LPO sets output to approximately 60% of
    * Default setting when first starting the engine is MPO, which is
    manageable for beginners.
    * Smart Learning Operation (SLO)-Mode function allows newer riders
    to become familiar with the handling and response of the JET SKI
    watercraft at a more relaxed pace before unleashing the full power of
    the supercharged engine.
    * A separate SLO-Mode key that restricts operation to SLO-Mode is
    coloured bright yellow, making it easy to distinguish from the FPO key.

    Kawasaki Smart Steering

    * The KSS (Kawasaki Smart Steering) supplementary steering system is
    designed to assist new riders as they learn turning and manoeuvring of
    a personal watercraft.
    *Ideal for novice riders, can be easily disconnected for more advanced riders.

    KSRD (Kawasaki Smart Reverse with Deceleration) -NEW

    * Kawasaki Smart Reverse with Deceleration electrically deploys the reverse bucket.
    Activated with a thumb switch on the right handle, it enables thrust to be controlled with one hand. When fully deployed, the reverse bucket contributes to deceleration.

    * To reverse the JET SKI, simply push the thumb switch. This will fully
    deploy the reverse bucket and apply thrust. Pushing the thumb switch
    farther increases the thrust.
    * In addition to “Forward” and “Reverse” modes, a “Neutral” drive mode,
    where the reverse bucket is partially deployed, helps keep the JET
    SKI in place when idling. To engage “Neutral” from “Forward” mode,
    release the throttle lever and gently push and release the thumb switch.
    From “Reverse” mode, simply releasing the thumb switch will engage

    Reverse Assist
    * With the reverse thumb switch fully depressed, the Trim control buttons
    (UP/DOWN) can be used to increase/decrease engine rpm to adjust
    thrust. This feature is handy when backing the JET SKI out of trailer
    into the water.
    * When the reverse thumb switch is released, rive mode switches to
    Neutral and the engine returns to idling.

    Lightweight Hull
    Loaded with technology from Kawasaki’s championship winning
    machines, the race-developed hull handles with precision and
    control, with a high level of seaworthiness – and at speeds from
    idle to its impressive top end. Specifically designed to handle the
    enormous output from the supercharged engine, the hull achieves
    a balance of strength and light weight.
    * Deep-V hull design enables banked turning performance. This
    reduces the lateral G-loads imposed on riders during turns, allowing
    them to better concentrate on riding. Measuring 22.5°, the idealised
    V-angle at the bottom of the hull helps prevent spinouts during sharp
    turns. As a result, the ULTRA 310 Series models deliver the neutral
    handling and turning characteristics for which Kawasaki JET SKI
    watercraft are famous.
    * Feedback from Kawasaki’s numerous IJSBA championship winning
    racing machines contributed to a hull specially designed to cope with
    the engine’s massive output while offering precise performance and
    responsive handling in both calm and choppy-water conditions.
    * The bottom of the hull slants upwards steeply from the centre section to
    the bow, allowing the ULTRA 310 Series models to penetrate swells and
    waves with less shock. At low speeds the result is great composure; at
    higher speeds the massive thrust enables the hull to push through most
    waves rather than bounce over top of them.
    * The lower hull is specially designed to distribute the engine and power
    delivery loads over a wide area.
    * With hull thickness determined based on a detailed strength analysis,
    the hull offers an idealised strength balance matched to the engine’s
    high output, and a lightweight package.

    Ride Plate

    * A groove running from the centre to the rear of the ride plate makes it
    easier to hold a straight course when running straight ahead.

    Quattro KSD - Kawasaki Splash Deflectors
    * Ridges across the bottom of the bow, Kawasaki Splash Deflectors
    deflect water splashing forward from under the hull. A fourth splash
    deflector mounted at the top reduces spray during high-speed turns.
    Whether turning or blasting straight ahead, at high speeds or low, the
    Quattro KSD minimises spray, allowing greater rider concentration.

    Increased Splash Protection -
    * Front bumper is 50 mm taller, offering increased splash protection for improved
    comfort. Channels in the bumper allow water that sprays up onto the bonnet to be
    redirected overboard.

    * At its tallest, the rear bumper is 100 mm higher, making it harder for water to wash on deck during tight, banked turns.
    Extensive Cruising Range - NEW
    * Offering more fuel capacity than any machine in its class, the fuel tank
    holds 80 litres of fuel. At cruising speed (70kph, in ECO mode this will yield approx 150km's of range in ideal conditions with 1 Rider and 10kg of luggage)

    *Kawasaki's use the Marine law. 1/3 out, 1/3 back, 1/3 in reserve. The Kawasaki will tell the rider they are on LOW fuel when the tank see's 1/3 remaining. This is equal to approx 28Litres of fuel and almost enough to travel a further 50klms.
    * Sponsons extend from the hull to provide stable straight-line
    performance (e.g. porpoising from start is minimised, etc) while helping
    to retain the machine’s narrow overall design. They also contribute
    significantly to the superb manoeuvrability when changing direction
    (particularly at higher speeds).

    Built-in Cleaning System
    * The ULTRA 310 Series models feature a built-in cleaning system to
    purge seawater used to cool the engine and intercooler. There are two
    separate circuits (one for the engine, one for the intercooler), each with
    a dedicated flushing port on the transom. Fitting a separate connecting
    tube is quick and easy. (Flushing the engine requires the engine to be
    running; flushing the intercooler requires the engine to be off.)

    Dynamic Luxury Styling
    All-new from the deck up, the 2022 ULTRA 310 Series models were
    completely restyled to give them a fresh image. Their “dynamic
    luxury” design maintains the dynamism of their predecessors
    while adding a three-dimension feel, and a high attention to
    detail ensures a luxurious, high-grade finish for each of the three
    distinctive, head-turning designs.

    * Sleek, dynamic styling, headed by an aggressive intake-style design at
    the bow, conveys their sporty prowess and ensures that these JET SKIs
    stand out on the water.
    * Designers carefully crafted parts with a three-dimensional feel to complement
    the dynamic styling, expertly weaving these pieces together to create a high-grade,
    bespoke design.
