The first jet ski we ever bought as a company was a 2018 Yamaha VX-C that we found through a friend of a friend in Pattaya. The seller was an expat moving back to Australia. The bill of sale was written on the back of a 7-Eleven receipt. The ski had 110 hours on it, ran like new, and cost us ฿180,000.
It also turned out to be unregistered with the Marine Department, which we discovered six weeks later when a harbour master in Patong asked for the paperwork and we didn't have any.
That's how most foreigners buy their first jet ski in Thailand. Cheap, fast, and missing a step. This piece is the version of that story we wish someone had told us four years ago.
New vs second-hand — the real price gap
A new Sea-Doo GTI Pro 130 from the official Thai distributor (Pongphat in Bangkok, Mongkol in Phuket) runs ฿520,000 – ฿580,000 on the road, drive-away, in 2026. A new Yamaha VX-C is a touch lower at ฿470,000. The Yamaha FX SVHO with supercharger and Bluetooth is ฿920,000, give or take a bonus pack.
A two-year-old second-hand version of any of those, with under 200 hours on the engine, sells in Phuket and Pattaya right now for roughly half. Sea-Doo at ฿260,000. Yamaha VX at ฿230,000. FX SVHO at ฿480,000.
The new-versus-second-hand decision is almost never about money. It's about which mechanic you trust to assess the engine you can't see.
The 50% saving on second-hand sounds compelling. It's compelling until you have to spend ฿78,000 on a hull crack the previous owner didn't disclose, or ฿32,000 on an impeller they ran through sand and never mentioned. We've owned five second-hand skis in four years. Two were great. Three needed work in the first 90 days totalling ฿110,000–฿140,000 each. Run those numbers honestly before you buy.
The four hidden costs every first-time buyer misses
- Marine Department registration (~฿4,500 + 1 week). Every recreational craft over 5 horsepower needs a Thai blue book. The dealer handles it on a new ski; on a second-hand purchase you go to the Marine Office yourself and the previous owner's signature must be on the transfer form.
- Mooring or trailer storage (฿4,000–฿8,000/month). You cannot legally leave a jet ski parked on a public beach overnight in Thailand. Marina dry-storage is the realistic option. Patong Marina, Boat Lagoon, Ao Por Marina — these are the three on Phuket.
- Insurance (฿15,000–฿25,000/year for liability + collision). Required if you ever rent it commercially, optional but recommended for private use. Most Thai insurers don't cover jet skis without a separate marine policy — your standard car insurance won't transfer.
- Service intervals (~฿8,000 every 50 hours, ~฿18,000 every 100 hours). Both Sea-Doo and Yamaha specify saltwater service intervals that are HALF the freshwater number. Skip them and you'll spend ฿200,000+ on a top-end rebuild in year three.
Add those up: roughly ฿100,000 per year in running costs for a private-use ski stored properly, registered, insured, and serviced on schedule. That's before fuel.
What we'd buy today, knowing what we know
Three rules — these are honestly the rules we use when adding to our fleet now:
- Sea-Doo GTI Pro 130 for the workhorse role. Reliable, parts available in Bangkok, fuel-efficient, easy to insure. We'd buy a 1-year-old second-hand at ฿310,000 over a new at ฿540,000 every time — as long as the engine compression test passes.
- Yamaha VX-C for the entry-level / pillion role. Two-person friendly, lower top speed (which is a feature for guest rentals, not a bug), and the cheapest 100-hour service in Thailand. New at ฿470,000 is fair.
- Buy second-hand only from a marine workshop, not a private seller. Workshops do PDIs (pre-delivery inspections) and document them. A private seller usually doesn't. The ฿15,000–฿20,000 premium a workshop charges is the price of certainty.
The 7-Eleven receipt ski
That first Yamaha VX-C we bought on the back of a 7-Eleven receipt? We sold it three years later, properly registered, for ฿120,000 — to a friend who'd watched the whole saga and decided he wanted a project. Two months after he bought it, the supercharger ate itself. He sold it for parts at ฿35,000.
Don't be us. Don't be him. Pay the workshop premium, take the inspection, and read the Marine Department transfer form before you sign it.
