Describe what your jet ski is doing. Get the parts that fix it.

Enter your year, make and model, tell us the symptom in plain English, and our AI mechanic walks you through the likely causes — then shows you the exact parts that fit your machine. Free, no account needed.

Won't start. Won't hit full speed. Steering gone stiff. Reverse stuck. Overheating. Instead of scrolling through forum threads about somebody else's ski, get an answer built around your year, make and model — and stop ordering parts that turn out not to fit.

Takes about a minute. No email required to see your results.

How it works

1. Pick your machine. Year, make and model. This is what makes the answer useful instead of generic — a 2006 GTI and a 2016 GTI fail differently and take different parts.
2. Describe the problem in your own words. "Cranks but won't fire." "Bogs over half throttle." "Steering got really stiff this season." No technical vocabulary required.
3. Get causes, checks, and parts. You get the most likely causes ranked, the checks to confirm which one it is, and the parts that fit your ski if you need them.

What it can help you diagnose

Most common PWC complaints, including:

• Starting problems — won't start, cranks but won't fire, just clicks, dead after sitting, won't start after flipping
• Power and speed — won't reach full speed, loses power at full throttle, bogs under load, revs high without accelerating
• Steering, reverse and throttle — stiff or notchy steering, frozen reverse lever, sticky throttle
• Pump and drive — vibration under acceleration, growling from the back, cavitation, worn wear ring or impeller
• Overheating and cooling — running hot, alarm sounding, poor water flow
• Electrical and charging — battery keeps dying, not charging, warning lights and fault codes
• Water where it shouldn't be — water in the hull, carbon seal failure

Why this isn't just a chatbot

• It knows your platform, not just your brand. It won't sell you a reverse cable for a ski with electronic iBR, or a throttle cable for a drive-by-wire model — because those machines don't have one. Generic advice gets this wrong constantly and it's how people end up with parts they can't use.
• Parts are matched to your exact machine. Recommendations are tied to the year, make and model you entered, so you're not eyeballing whether something fits.
• It tells you when it isn't sure. If a symptom has several plausible causes, it says so and gives you the check that tells them apart, instead of guessing confidently and costing you money.

What it can't do

Being straight with you: it can't see, hear, or touch your ski. It can't run a compression test, pull a fault code off your gauge, or tell you a cylinder is scored. What it does is narrow the possibilities fast, tell you which check to run first, and make sure that when you do order a part, it's the right one for your machine. If you'd rather have a person look at it, get in touch and we'll help.

Questions people ask

Is it free?

Yes, and no account is required. You'll never be asked to pay to see your diagnosis, and you're not obligated to buy anything.

How accurate is it?

It's strong at narrowing a symptom to the two or three most likely causes and pointing you at the right parts, because it follows the same diagnostic order a technician does. It can't replace a physical inspection. Use it to skip the guesswork, then confirm with the checks it gives you.

Will the parts actually fit my ski?

Parts are matched to the exact year, make and model you enter. Model-year changes are where most wrong-part orders happen, so still confirm the fitment note on the product page before you check out. If anything's ambiguous, ask us first — that's free too.

What if I don't know the right words for the problem?

Describe it how you'd describe it to a friend. "Makes a grinding noise when I hit the gas" works fine. That's the point of it.

Can I talk to a real person?

Yes. If the answer isn't clear or you want a second opinion before spending money, contact us.
