Kawasaki Ultra 310LX 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 310LX for sale

The LX is the fully loaded Ultra 310. On top of the supercharged engine and big hull, it adds the JETSOUND 4s audio system, so you can play music without a separate speaker. It also gets the full colour TFT display with smartphone connectivity, LED accent lights and the Ultra deck.

The Supercharged Heart of the Kawasaki Ultra 310LX 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. Many repeat customers come back for a second Kawasaki Ultra 310LX for sale.

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 310LX for sale Suits

Long distance and open water

A 21 gallon tank and a big, dry hull make the Kawasaki Ultra 310LX 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 310LX for sale Rides

Sit on the Kawasaki Ultra 310LX 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 310LX for sale is covered here too.

Kawasaki Ultra 310LX 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 310LX 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.

The People Who Order This Ski

We ship the Kawasaki Ultra 310LX for sale to weekend riders, families with lake houses, coastal tour operators and rental fleets in many countries. Some buy one ski, some buy six. We treat both the same way: confirm the model, quote delivery and keep you updated until it lands.

Living With the Kawasaki Ultra 310LX 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.

Getting Comfortable

Every ski feels a little different. Spend your first hour learning how the Kawasaki Ultra 310LX for sale responds at low speed, how it turns and how it stops. Practise in open water away from swimmers and boats. Once that feels natural, add speed a little at a time.

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.

A Two Minute Check Before Every Ride

Look in the engine bay for loose hoses, fuel smell or water. Check the fuel level and the battery. Make sure the intake grate is clear and the drain plugs are in. Attach the lanyard, check the steering moves freely and tell someone where you are going. It takes two minutes and catches most problems before they spoil a day. It is worth remembering when you ride the Kawasaki Ultra 310LX for sale.

Coming Alongside a Jetty

Most bumps happen at walking pace. Approach slowly, aim a little upwind or upstream of where you want to stop and let the drift bring you in. A fender on the side you are docking on saves the hull. Practise a few times on a quiet day and it soon becomes easy.

Reading the Weather

Check the forecast before every ride, especially wind. A lake that is glassy at nine in the morning can be choppy by two. On the coast, watch for offshore winds that make it hard to get back. If the weather turns, head in early. Nobody ever regretted coming back half an hour sooner. That is a big part of why people choose the Kawasaki Ultra 310LX for sale.

Riding in Cooler Water

Cold water takes your strength faster than you think. If the water is cool, wear a wetsuit or drysuit, keep rides shorter and stay closer to shore. Riding with a friend is always a good idea, and more so when the water is cold.

The First Hours

New engines like variety. For the first few hours keep changing speed and do not hold the Kawasaki Ultra 310LX for sale flat out for long. After the break-in period in the manual, book the first service. Fresh oil and a once over by a mechanic set the ski up for the years ahead.

Maintenance on the Kawasaki Ultra 310LX 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.

Pump and Intake Care

Most performance problems on a jet ski come from the pump. Weed, a plastic bag or a rope around the intake can make the ski lose speed or overheat. Turn off the engine before clearing it. Over time sand wears the impeller edges and the wear ring, so the pump loses grip. Have them checked at each service, especially if you ride in shallow or sandy water. Owners of the Kawasaki Ultra 310LX for sale tell us the same thing.

What It Costs to Run

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.

Beyond fuel, the main costs are the annual service, insurance where required, and storage. Compared with a boat, a jet ski is cheap to own. It is one of the reasons we keep the Kawasaki Ultra 310LX for sale in stock.

Riding in the Sea

Sea riding is great fun, but salt finds every gap. Flush after each ride, rinse everything with fresh water, and open the seat to let the engine bay dry before covering. Check metal parts, battery terminals and trailer fittings for corrosion every few weeks.

Keeping the Hull and Seat Looking New

Rinse the hull after every ride and wipe off water spots. A coat of marine wax a few times a season keeps the finish bright and makes cleaning easier. Use a vinyl protectant on the seat to stop it cracking in the sun. If the ski lives on a lift or trailer outside, a fitted cover is the best money you will spend. You get all of that with the Kawasaki Ultra 310LX for sale.

Battery Tips

Most no start problems on jet skis come down to a flat battery. If the ski will sit for more than a week or two, connect a smart charger or disconnect the battery. Keep the terminals clean and tight. Audio systems and displays draw power, so do not play music for hours with the engine off.

Using the Tech

Spend ten minutes with the manual learning the display, modes and alerts. Many owners never use features they paid for, like slow speed modes or fuel economy readouts. Knowing them makes riding easier and helps you spot problems early. Ask us if you want photos of the Kawasaki Ultra 310LX for sale before it ships.

Trailering and Launching

A good trailer with properly set bunks protects the hull. Strap the ski down at the bow and stern, and check the straps after the first few kilometres. At the ramp, back in until the ski floats, start it once it is in the water and never run it on the trailer. When you pull out, drain the bilge and rinse the trailer if you were in salt.

Storage Between Seasons

For winter or long breaks, top up the tank with stabilised fuel, run it through, change the oil, prepare the engine as the manual describes and keep the battery on a maintainer. Store the ski under cover with the seat slightly open for air flow. We are happy to answer questions about the Kawasaki Ultra 310LX for sale by email or chat.

Keeping It Secure

Jet skis are easy to tow away, so lock the trailer hitch and use a wheel clamp if the ski sits outside. Take the key or lanyard with you. Note the hull identification number and keep photos of the ski. Many owners also fit a small GPS tracker for peace of mind.

Ride Safe

Life jackets for everyone, the lanyard always attached, and eyes open. Jet skis are fast and quiet, and other water users may not see or hear you. Never ride after drinking, avoid riding at night unless the ski and local rules allow it, and always watch your speed near beaches and marinas. The Kawasaki Ultra 310LX for sale handles this well.

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.

Papers You Will Need

Expect to need the invoice, the certificate of origin or equivalent, and the hull number for registration and insurance. Requirements differ by country. Tell us where the ski will be registered and we will make sure the paperwork matches. This is where the Kawasaki Ultra 310LX for sale earns its keep.

Towing Tubes and Skiers

If you plan to tow, check your local rules first. Many places require a spotter or a three seat ski. Use a proper tow rope, start slowly and agree on hand signals with the person being towed. Turn wide and smooth, and keep well away from other boats and the shore.

Common Problems and Quick Checks

Will not start. Check the lanyard is attached, the battery is charged and the kill switch is reset. Plenty of buyers message us before ordering the Kawasaki Ultra 310LX for sale, and we like that.

Revs but no speed. Something is probably caught in the intake grate. Stop the engine and clear it.

Overheat warning. Stop, check the intake for weed and flush the cooling system when you are back. Keep that in mind with the Kawasaki Ultra 310LX for sale.

Bilge water. A little is normal. A lot means a check of hoses and seals is due.

Warning light. Slow down, read the display message and check the manual before carrying on. That applies to the Kawasaki Ultra 310LX for sale as much as any ski.

Avoid These Common Errors

The most common problems we hear about are self inflicted: sand in the pump from shallow water, corrosion from skipping the flush, flat batteries from long storage and riders forgetting that a jet ski needs throttle to turn. A little care avoids all of them.

The First Year

Year one is easy if you keep to a routine. Follow the break-in, get the first service on time, flush after every ride and check the intake regularly. Before winter or a long break, store it properly. The ski will reward you with trouble free seasons. Many repeat customers come back for a second Kawasaki Ultra 310LX for sale.

What to Add on Day One

Most people start with a cover, a trailer, life jackets, a tow rope and a dry bag. After a few rides you will know what else you want. We can include accessories in the same shipment to save on freight.

Jet Ski or Small Boat?

A jet ski costs less to buy, less to run and is far easier to launch, tow and store than a boat. It goes where boats cannot, like shallow bays and narrow channels. A boat carries more people and gear and offers shelter. For one to three people who want fun and freedom, a jet ski is hard to beat. The Kawasaki Ultra 310LX for sale is covered here too.

Thinking Ahead to Resale

A well kept ski from a major maker is easy to sell later. The things buyers ask for are simple: service history, low hours for its age, no hull damage and a clean engine bay. Look after those and you will get a fair price when you move on.

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. It is worth remembering when you ride the Kawasaki Ultra 310LX for sale.
