With model year 2027 (MY27), Sea-Doo raises the bar considerably: a new 350-hp class, a spectacular special edition and a fresh Spark generation. The good news first, the new models are fully compatible from day one with the M-JET Flasher and the M-JET Diagnostic.
What is new for model year 2027
The new 350-hp class
At the heart of MY27 is the supercharged Rotax 1630 ACE, now producing around 350 hp. It powers the flagship models:
- RXP-X 350, the uncompromising muscle craft
- RXT-X 350, performance with long-distance comfort
- GTX Limited 350, the luxury tourer
- RXP-X Senna 350, the exclusive special edition
New Spark generation
The entry level gets sportier in 2027 too. New arrivals are the Spark X and the Spark X TRIXX, based on the new Rotax engine generation (1000 ACE), light, agile and ideal for app-based tuning.
Proven models continue
Classics such as the GTI, GTR, GTX 170/230, GTR-X 300, Wake, FishPro and Explorer Pro remain in the line-up and are of course covered as well. You will find a complete overview in our model overview.
Fully compatible with the M-JET Flasher
The M-JET Flasher is a plug-and-play tuning tool: plug it into the diagnostic port, connect via smartphone, pick the right stage and flash in a few minutes. You get noticeably more power, a more direct throttle response and more top speed and you can reset every change back to stock at any time.
Note on the ECU unlock: The 325/350-hp models and the 2027 Spark models use a locked Bosch-MG1 ECU. A one-time ECU unlock is required here. You can send in your ECU or choose a prepared replacement ECU, the Flasher then transfers all relevant data. You can see all options and prices directly in the configurator.
Diagnostics with M-JET Diagnostic
Besides tuning, the M-JET Diagnostic covers full diagnostics for the MY27 vehicles: read and clear fault codes, view live data, run service functions and manage keys, all from the app over Bluetooth. That keeps your Sea-Doo under control all season long.
