Kawasaki Ultra 310X SE for sale: Specifications

Figures can change a little between model years, so the paperwork that comes with the ski is the final word. The maker keeps the current specs on its Ultra 310 page on Kawasaki.com if you want to compare models.

Trim and Equipment on the Kawasaki Ultra 310X SE for sale

The 310X SE is a special edition of the earlier generation Ultra 310. It has the same supercharged 1,498 cc engine, the deep V Ultra hull and the luxury trim Kawasaki gave its SE models. Because it is an earlier generation, we confirm the exact model year and equipment of the unit with you before you order.

The Supercharged Heart of the Kawasaki Ultra 310X SE for sale

The Ultra 310 is Kawasaki’s flagship. Under the seat sits a 1,498 cc inline four, the same basic block as the STX 160, but this one is fed by an Eaton Twin Vortices supercharger with an air to water intercooler. Boost runs to about 16.8 psi and the compression ratio drops to 8.2 to 1 to handle it.

Power goes straight to a 160 mm axial flow jet pump with a stainless three blade impeller. That big pump is what turns the supercharger’s shove into real acceleration, even with two adults on board and a full tank. We are happy to answer questions about the Kawasaki Ultra 310X SE for sale by email or chat.

Kawasaki adds rider aids so the power is usable. Power Modes let you soften things for a beginner or a passenger. Launch Control stops the bow standing up when you nail it from a stop. Kawasaki Smart Reverse with Deceleration gives you braking and a proper reverse from a lever on the left bar.

Who the Kawasaki Ultra 310X SE for sale Suits

Long distance and open water

A 21 gallon tank and a big, dry hull make the Kawasaki Ultra 310X SE for sale a real touring machine. Owners do island hops, coastal runs and lake crossings that would wear you out on a smaller ski.

Two up and three up riding

There is room for three adults, and the power does not fade with weight. Families who ride together like that.

Towing

With supercharged torque and a long hull, pulling a tube or a skier is easy. Check your local rules on seating and spotters.

Riders who want the top model

Some people just want the best one Kawasaki makes. This is it.

How the Kawasaki Ultra 310X SE for sale Rides

Sit on the Kawasaki Ultra 310X SE for sale and the first thing you notice is the size. The Ultra hull is long and wide, so it feels planted at the dock and stable when people climb on from the back.

Open the throttle and it simply goes. The supercharger pulls hard all the way up, and the deep V hull cuts through chop instead of slapping over it. On a long run across open water this is where the Ultra makes sense: you arrive less tired. The Kawasaki Ultra 310X SE for sale handles this well.

Kawasaki Ultra 310X SE for sale or an STX 160?

The STX 160 is lighter, cheaper and more playful in tight turns. For lakes, rivers and short sessions it is plenty.

The Kawasaki Ultra 310X SE for sale is for people who ride far, ride loaded or ride in rough water. It costs more and burns more fuel when you use the power, but nothing in the Kawasaki range is as fast or as comfortable.

Who Buys the Kawasaki Ultra 310X SE for sale From Us

Most of our buyers are private owners who want a new ski at a clear price without the usual showroom games. After them come rental companies, resorts and tour operators adding to their fleets, and dealers who need stock. What they all want is the same: the right model, proper paperwork and a ski that arrives in one piece.

Living With the Kawasaki Ultra 310X SE for sale

Day to day, a modern four stroke ski is easy. You launch, press start and ride. Afterwards you flush the engine, rinse the hull and put the cover on. There is no oil to mix, no choke and no hard starting on cold mornings. Look after it and it will give you years of easy weekends.

Your First Rides on the Kawasaki Ultra 310X SE for sale

Take the first rides somewhere quiet. Get used to the throttle, the steering and, if fitted, the brake and reverse lever. Remember a jet ski needs throttle to steer. If you let off completely, it goes straight. Practise slow turns, docking and coming alongside a jetty before you go fast or carry passengers.

Taking People With You

A loaded ski handles differently. It takes longer to stop, leans more in turns and needs more throttle to get going. Ride smoother with passengers, give them a heads up before changes in speed and never exceed the rated capacity.

Before You Leave the Beach

Fuel, battery, drain plugs, intake grate, lanyard, life jackets. Run through that list every time. Open the seat and sniff for fuel, and look for water in the hull. If anything looks wrong, sort it on land, not halfway across the bay. This is where the Kawasaki Ultra 310X SE for sale earns its keep.

Docking Without Drama

Come in slowly, at an angle, and use short bursts of throttle to steer. If your ski has brake and reverse, use it gently to slow the last metre. Have a line ready at the bow and someone on the dock if you can. Wind and current push a light ski around more than you expect, so allow for them before you get close.

Wind, Waves and Timing

Morning water is usually the calmest. Plan longer rides early and keep the afternoon for short sessions near the launch. Learn what your local water does when the wind swings, and always leave enough fuel to fight a headwind on the way home. Plenty of buyers message us before ordering the Kawasaki Ultra 310X SE for sale, and we like that.

Early and Late Season Riding

Spring and autumn can be the best riding of the year, with quiet water and fewer people. The water is colder though, so dress for a fall, carry a phone in a dry bag and keep to familiar places.

Breaking In the Kawasaki Ultra 310X SE for sale

Follow the break-in in the owner’s manual. Usually that means varying speed for the first hours, avoiding long periods at full throttle and having the first service done on time. Engines that are broken in gently tend to run better for longer.

Maintenance on the Kawasaki Ultra 310X SE for sale

• Flush the engine with fresh water after every ride in salt or dirty water.
• Rinse the hull, pump and trailer.
• Check the intake grate for weed, rope and plastic.
• Change the engine oil and filter at the hours in the manual, or once a year.
• Check the battery and keep it charged between rides.
• Grease the pivots and fittings listed in the manual.
• Inspect the impeller and wear ring each season.

None of this needs special skills. Most owners do the basics and pay a mechanic for the annual service.

Looking After the Jet Pump

There is no propeller on a jet ski. Water is drawn through a grate under the hull, pushed by an impeller and squirted out the back. Sand, gravel and weed are the enemies. Avoid running in very shallow water, and if the ski starts to rev without pulling, check the intake grate first. A worn impeller or wear ring will also make the ski feel slow, and both are normal service parts. Keep that in mind with the Kawasaki Ultra 310X SE for sale.

Fuel Use and Running Costs

A supercharged 1.5 litre burns more fuel than a naturally aspirated ski when you use the throttle hard. Cruise at moderate speed and the big tank gives you a long range. Kawasaki recommends premium unleaded for the supercharged engines, so check the manual and fuel accordingly.

Fuel use depends on how you ride. Cruising at a steady speed is far cheaper than running flat out. Parts and servicing for big brands are easy to find in most countries, which keeps long term costs sensible. That applies to the Kawasaki Ultra 310X SE for sale as much as any ski.

Salt Water Care

Salt is hard on any machine. After every salt ride, flush the engine through the flush port, rinse the hull, pump and trailer, and dry the engine bay. A spray of corrosion inhibitor under the seat now and then helps a lot. Do not leave the ski sitting in salt water for days if you can avoid it.

Looking After the Finish

Sun and salt fade paint and seats faster than anything. Rinse, dry and cover after each ride, wax the hull now and then and treat the seat with a UV protectant. A clean ski also makes it easier to spot small cracks or loose fittings early. Many repeat customers come back for a second Kawasaki Ultra 310X SE for sale.

Keeping the Battery Healthy

A small battery works hard on a jet ski. Use a maintenance charger between rides, keep the terminals clean and check the battery is held down tight. If the starter turns slowly, charge or replace the battery before your next trip.

Displays and Electronics

Modern skis carry a lot of electronics: digital displays, rider modes, audio and sometimes GPS. Keep the display covered when parked, rinse it with fresh water after salt rides and update apps or software when the maker releases updates. Read the display warnings. They usually tell you exactly what needs attention. The Kawasaki Ultra 310X SE for sale is covered here too.

Towing and the Ramp

Check tyre pressure, lights and wheel bearings before each trip. At the ramp, have everything ready before you back in so you do not block others. Launch, move the ski away, then park the car. Coming back, line the ski up slowly and winch it on.

Laying It Up

Before a long break, flush and dry the engine, treat the fuel, change the oil and charge the battery. In freezing climates follow the manual’s winterising steps so no water stays in the cooling system. A breathable cover keeps dust and sun off. It is worth remembering when you ride the Kawasaki Ultra 310X SE for sale.

Theft Prevention

A hitch lock, a wheel clamp and a cover that hides the model go a long way. Store the key separately, record the hull number and keep your purchase papers safe. If the ski lives at a marina, ask about their security before you sign up.

Safety Gear and Common Sense

Everyone on board should wear a life jacket. Clip the lanyard to your wrist or vest every time you ride, so the engine stops if you fall off. Carry a whistle, a tow rope and a phone in a dry bag. Keep a safe distance from swimmers, divers and boats, and ride slowly near shore. That is a big part of why people choose the Kawasaki Ultra 310X SE for sale.

Licences and Local Rules

Rules for jet skis vary by country and even by lake or harbour. Some places need a licence or boating certificate, registration, insurance or minimum age limits. Check with your local authority before you ride. We supply the paperwork you need to register the ski where you live. The Personal Watercraft Industry Association also shares general riding and safety advice at pwia.org.

Insurance and Registration

In many countries a jet ski must be registered and insured before you ride. Even where it is not required, insurance is worth it for theft, damage and liability. Your insurer will usually want the hull number, the purchase invoice and photos. We supply the documents you need. Owners of the Kawasaki Ultra 310X SE for sale tell us the same thing.

Pulling a Tube or a Skier

Towing is one of the best things about a three seat ski. Use a rope rated for the job, keep a spotter on board where the law requires it, and give your rider a gentle start. Wide turns keep the tube from whipping into the wake.

Quick Fixes Before You Call a Mechanic

No start: lanyard on, battery charged, terminals tight. It is one of the reasons we keep the Kawasaki Ultra 310X SE for sale in stock.

Loss of thrust: clear the intake grate with the engine off.

Overheating: weed or sand in the intake or cooling system. You get all of that with the Kawasaki Ultra 310X SE for sale.

Rough running: old fuel or water in the fuel. Start there.

Steering feels vague: check the nozzle and steering cable for damage. Ask us if you want photos of the Kawasaki Ultra 310X SE for sale before it ships.

Mistakes New Owners Make

Running in shallow water and sucking up sand. Forgetting to flush after salt rides. Leaving the battery to go flat over winter. Overloading the ski. Letting go of the throttle in a turn and wondering why it will not steer. All easy to avoid once you know.

What a Typical First Season Looks Like

Most owners ride gently for the first few weekends, then get the first service done. After that it is simply riding, flushing and covering. Halfway through the season, check the intake, battery and hull. At the end, prepare it for storage. That is all most people need to do in year one. We are happy to answer questions about the Kawasaki Ultra 310X SE for sale by email or chat.

Useful Accessories

A fitted cover, a good trailer, a dock line, an anchor or sand anchor, a tow rope and a dry bag are the basics. Many owners add a boarding step or a cooler. Ask us when you order and we can quote accessories with the ski.

Why People Choose a Jet Ski Over a Boat

Lower cost, easier launching, cheaper fuel bills and a lot more fun per hour on the water. You can tow it with an ordinary car and store it in a garage. If you need to carry a big group, a boat makes sense. For most riders, a ski does the job better. The Kawasaki Ultra 310X SE for sale handles this well.

Resale Value

Big brand jet skis hold their value well, especially when they come with service records. Keep receipts, follow the service schedule and store the ski under cover. When the time comes to upgrade, a clean ski with a full history sells quickly.

Buying for a Business

Resorts, rental fleets and tour companies buy from us too. We can quote fleet orders, ship them together and supply the paperwork your local authority asks for. Ask about service intervals for commercial hours, which are often shorter than for private use. This is where the Kawasaki Ultra 310X SE for sale earns its keep.
