If you’re looking for one of the nicest turnkey Ultra 310R packages available, you’ve found it. Garage Kept

And remember, boating season in Southern Utah is LONG! October in St. George has been known to hit 100°, and Sand Hollow and Quail Creek are open year-round. Warm, sunny afternoons can make for great riding well into the fall, and plenty of people still get out on the water midday even during the winter months. One of the best places around to own a pair of Jetski’s!

I’m selling my pair of 2015 Kawasaki Ultra 310R jet skis with 211 and 214 original hours. These skis have been exceptionally well cared for, run beautifully, and have no known mechanical issues. They start easily, idle smoothly, and deliver the incredible acceleration the Ultra 310R is known for.

The engine compartments are exceptionally clean, and both skis have been professionally inspected. The current supercharger belts are in excellent condition and still have useful service life remaining, which is why I never installed the new Kawi Performance upgrades.

These skis have normal cosmetic wear consistent with 11-year-old watercraft (minor dock rash and scratches), but they have been meticulously maintained mechanically.

Premium Kawi Performance Upgrades Included

When I bought these skis, I intended to keep them for many years, so I invested in premium preventative maintenance upgrades. My plans changed before I ever installed them.

Included are:

• (2) Brand-new Kawi Performance Automatic Tensioner Arms (currently around $380 each)

• (2) Brand-new Kawi Performance Heavy-Duty Supercharger Belts

• Spring holder installation tool

• OEM Oil Filters

• Extra Spark Plugs

That’s well over $900 in brand-new Kawi Performance parts included with the sale.

According to Kawi Performance, the upgraded automatic tensioners increase belt tension by approximately 15–20%, helping reduce belt slip, improve supercharger performance, and dramatically extend belt life. Kawi Performance also reports that many customers find the upgrade eliminates the need for future belt replacements under normal recreational use.

These upgrades are included because I planned on owning these skis long-term—not because they needed them.

Premium Trailer Included

The matching trailer has also been upgraded.

Brand-new trailer tires (over $400 invested)

Brand-new matching spare tire

Aluminum wheels

Lockable front storage/cargo box

Integrated rack capable of carrying five fuel cans

The trailer is ready for long-distance trips and has been set up to be dependable and convenient.

Why I’m Selling

I purchased these skis because I planned to keep them for many years. Since then, my boating interests have changed, so rather than letting them sit, I’d rather see someone else enjoy them.

These have been cared for by an owner who believes in preventative maintenance—not waiting until something breaks.

If you’re looking for one of the nicest Ultra 310R packages available with premium upgrades already included, these are worth a look.
