Yamaha vs Sea-Doo comes down to which lineup has the watercraft you want. On each brand's US website on October 20, 2026, Sea-Doo had the lowest entry price, $7,099 for the 2027 Spark, plus the only fishing models and a dedicated tow-sports series. Yamaha alone sold a stand-up model, and its FX HO started below Sea-Doo's GTX.

Prices are each brand's US starting prices, read October 20, 2026. Sea-Doo's exclude transport and preparation. Yamaha's model pages do not print a model year or say what the starting price includes, so ask the dealer for an out-the-door price. You can compare asking prices on new and used watercraft from both brands on Searchshop's boats for sale page.
This comparison uses only what Sea-Doo and Yamaha publish on their own US websites, read on October 20, 2026. Prices, engines, weights, fuel and storage figures come from each model's page, and lineup changes come from Sea-Doo's August 17, 2026 news release and Yamaha's August 23, 2026 WaveBlaster announcement. Models are paired by the segment each brand places them in and by starting price. Nothing here comes from test rides, and no reliability or resale claims are made.
Sea-Doo costs less to get into: the 2027 Spark for 2 starts at $7,099, against $8,999 for Yamaha's JetBlaster. The two take different approaches. The Spark is much lighter and carries less fuel, while the JetBlaster is heavier with a bigger tank but very little storage.

Sea-Doo also sells a Spark for 3 from $8,699, and the 2027 Spark X and Spark X Trixx get a 110 hp Rotax 1000 ACE, and Sea-Doo says the Spark X has a 15 percent higher top speed. Yamaha's JetBlaster range runs from $8,999 for the two-seat base model to $12,899 for the JetBlaster PRO 3-Up and JetBlaster LTD. Sea-Doo's spec tables list a Polytec hull for the Spark and GTI and a fiberglass hull for the GTX.
The mid-size family models are close on paper, with Yamaha's VX-C starting $700 below Sea-Doo's 2027 GTI 130. Both seat up to three riders and carry 18.5 gallons of fuel. The GTI has more storage, while the VX-C is the lighter of the two.

Yamaha's VX series is wider than Sea-Doo's GTI range. It climbs through the VX, VX Deluxe and VX Cruiser to the VX Cruiser HO at $16,399 and the VX Limited HO at $17,399, and the VX Cruiser HO uses Yamaha's 1.9-liter engine. Sea-Doo's step up within the GTI family is the GTI SE at $13,499. Buyers who want more than that from Sea-Doo move to the GTX touring models.
The touring and luxury models start $250 apart: $17,899 for Yamaha's FX HO and $18,149 for Sea-Doo's 2027 GTX 170. The FX HO is heavier and has more storage. The GTX 170 comes with a 10.25-inch touch display and a fiberglass hull.
| Published figure | Sea-Doo GTX 170 (2027) | Yamaha FX HO |
|---|
| Starting price | $18,149 | $17,899 |
| Engine | Rotax 1630 ACE, 170 hp | Yamaha 1.9-liter High Output, 1,898 cc |
| Dry weight | 796 lb | 908 lb |
| Fuel capacity | 18.5 US gal | 18.5 gal |

Higher up, Sea-Doo offers the GTX 230 from $19,149, the GTX 300 from $20,849 and the 350 hp GTX Limited from $23,849. Yamaha's FX series tops out with the FX Cruiser SVHO at $22,399 and the FX Limited SVHO at $22,999. Yamaha lists the FX HO at $18,599 with factory-installed audio.
Neither brand can be ranked on power from published data, because the two describe their engines differently. Sea-Doo rates its engines in horsepower. The Yamaha model pages checked for this article list engine family and displacement instead.
- For 2027, Sea-Doo's Rotax 1630 ACE produces up to 350 hp in the GTX Limited, RXT-X, RXP-X and the limited-edition RXP-X Senna 350. Sea-Doo calls it its most powerful factory engine.
- The same 1630 ACE family is rated at 130 hp in the GTI 130, 170 hp in the GTX 170, 230 hp in the GTX 230 and 300 hp in the GTX 300.
- Yamaha's 1.9-liter High Output engine displaces 1,898 cc. Yamaha calls it the largest-displacement engine in a personal watercraft today.
- The one Yamaha horsepower figure found for this article is for the 2027 WaveBlaster: 110 hp from its 1,049 cc TR-1 HO engine.
Displacement and horsepower measure different things, so a bigger Yamaha engine is not proof of more power than a smaller Sea-Doo one, or the other way around.
Each brand sells watercraft the other has no match for, and for some buyers that settles the choice. Sea-Doo covers fishing, exploring and tow sports with purpose-built models. Yamaha covers stand-up riding and one-person sport riding.
- FishPro Sport ($18,449) and FishPro Trophy ($22,949). Sea-Doo lists a cooler, rod holders and Garmin fish finders among FishPro features, and a livewell on the Trophy.
- Explorer Pro ($20,449), which Sea-Doo describes as built for long-distance discovery, with smart storage.
- Wake ($15,949) and Wake Pro ($20,149), which come with a board rack, ski pylon and Ski Mode.
- SuperJet ($11,999), a stand-up WaveRunner.
- WaveBlaster ($11,999), a single-rider WaveRunner. Yamaha says the 2027 model reaches dealers in the first quarter of 2027.
- CrossWave ($32,499), the highest-priced model in Yamaha's US WaveRunner lineup.
Yamaha's closest match to Sea-Doo's tow-sports models is the VX Limited at $15,999, which Yamaha bills as "Watersports Ready."
Both brands offer a system that gives forward, neutral and reverse for low-speed control, under different names. Sea-Doo calls its system iBR, for Intelligent Brake and Reverse, and lists it on the Spark and GTI. Yamaha calls its system RiDE and lists it on models including the VX, VX Cruiser HO and FX HO.
Sea-Doo says iBR is exclusive to Sea-Doo and has been recognized by the U.S. Coast Guard for improving safety, and that it lets riders engage forward, neutral and reverse for stable, easy maneuvers at low speeds. Yamaha says RiDE lets riders switch between forward, neutral and reverse with a single pull of the throttle for smoother deceleration, reversing and docking. Sea-Doo also offers iDF, a system that clears a clogged pump intake with a button, on models including the 2027 Spark X and GTX.
Buy the brand whose lineup has the type of watercraft you will actually use, then compare the two closest models on price and published specs. As a rough guide:
- Lowest price to start riding: Sea-Doo's 2027 Spark, from $7,099.
- Family recreation: compare the Sea-Doo GTI with the Yamaha VX-C or VX. Prices are close; the GTI has more storage and the VX-C weighs less.
- Touring with lots of storage: Yamaha's FX HO lists 44.5 gallons against 26.1 for the GTX 170.
- Fishing, exploring or a tow-sports setup from the factory: Sea-Doo FishPro, Explorer Pro or Wake.
- Stand-up or solo sport riding: Yamaha SuperJet or WaveBlaster.
Before you buy, get an out-the-door price that includes freight and preparation. For a used watercraft, work through Searchshop's checklist for buying a pre-owned PWC.

Sea-Doo has the cheaper entry model: the 2027 Spark starts at $7,099, against $8,999 for Yamaha's JetBlaster, on each brand's US website on October 20, 2026. Higher up the range the gap changes. Yamaha's VX-C starts at $11,599, below the $12,299 Sea-Doo GTI 130, and the FX HO starts at $17,899, just below the $18,149 GTX 170.
No. Yamaha's US WaveRunner lineup has no fishing-specific model; its series are JetBlaster, VX, FX, GP, Sport and CrossWave. Sea-Doo sells two fishing models for 2027, the FishPro Sport from $18,449 and the FishPro Trophy from $22,949, with features such as a cooler, rod holders and a Garmin fish finder.
The most powerful 2027 Sea-Doos use the Rotax 1630 ACE rated at 350 hp, which Sea-Doo calls its most powerful factory engine. It powers the GTX Limited, RXT-X, RXP-X and the limited-edition RXP-X Senna 350. Starting prices are $23,849 for the GTX Limited, $23,599 for the RXT-X and $23,699 for the RXP-X.
