Buying a Used Jet Ski? 10 Things You Should Check Before Handing Over Your Money

Buying a used jet ski can be a fantastic way to get on the water without spending the money required for a brand-new machine. However, not all used PWCs are created equal, and a cheap ski can quickly become an expensive project if you don't know what to look for.

Whether you're considering a Sea-Doo, Yamaha WaveRunner or Kawasaki Jet Ski, these checks can help you avoid costly surprises.

1. Check the Engine Hours

Most modern PWCs display engine hours through the gauge cluster.

Engine hours provide an indication of usage, but they don't tell the whole story.

A well-maintained ski with 300 hours can often be a better purchase than a neglected ski with 100 hours.

Ask:

• How was the ski used?

• Was it flushed after every ride?

• Was it serviced regularly?

Maintenance history is often more important than hours alone.

2. Inspect the Hull

Walk around the entire ski and inspect the hull carefully.

Look for:

• Cracks

• Deep gouges

• Poor quality repairs

• Gelcoat damage

• Signs of impact

Minor scratches are normal, but structural damage can be expensive to repair.

3. Look Inside the Hull

Remove the seat and inspect the engine compartment.

Warning signs include:

• Excessive corrosion

• Standing water

• Oil residue

• Loose wiring

• Salt deposits

A clean engine bay is often a sign of a well-cared-for ski.

4. Check for Service Records

Documentation is one of the best indicators of ownership quality.

Ask for:

• Service invoices

• Maintenance records

• Receipts for repairs

• Parts replacement history

A seller who keeps records is usually more likely to have maintained the ski properly.

5. Inspect the Jet Pump

The jet pump is one of the most important components on any PWC.

Check:

• Wear ring condition

• Impeller condition

• Signs of impact damage

• Excessive shaft movement

Pump repairs can quickly add up if major components need replacing.

6. Test the Battery and Electrical System

Electrical issues can be frustrating and expensive.

Check:

• Battery condition

• Gauge operation

• Start-stop function

• Reverse operation

• Warning lights

Any electrical faults should be investigated before purchase.

7. Check the Trailer

Many buyers focus on the ski and forget about the trailer.

Inspect:

• Tyres

• Wheel bearings

• Lights

• Winch strap

• Rust and corrosion

A trailer can easily require hundreds or even thousands of dollars in repairs.

8. Look for Signs of Saltwater Neglect

Saltwater use isn't a problem if the ski has been maintained correctly.

However, warning signs include:

• Corroded bolts

• White salt deposits

• Rusty components

• Damaged electrical connectors

These can indicate poor maintenance practices.

9. Water Test the Ski

If possible, always water test before purchasing.

Look for:

• Smooth acceleration

• Stable engine temperature

• No warning lights

• No excessive vibration

• Strong top speed

Many problems only become apparent when the ski is under load.

10. Research Parts Availability

Some older PWCs have limited parts availability.

Before purchasing, consider:

• Are genuine parts still available?

• Are aftermarket parts available?

• Are used parts readily available?

This is particularly important for older Honda AquaTrax, Polaris and discontinued models.
