What is the GPS Vmax limiter on the Sea-Doo 325 HP?
Sea-Doo installs a GPS-based speed limiter in its 325 HP models – RXP-X 325, RXT-X 325, and GTX Limited 325. This limiter activates via the GPS signal and cuts power at approximately 109 km/h (68 mph in USA/Canada) or approximately 112 km/h (70 mph) in international markets. The engine itself would technically be capable of significantly more – the limiter is a restriction imposed by the manufacturer.
Why is this limiter in place?
The GPS limiter is a safety and liability decision by BRP. It aims to prevent riders in sensitive waters, beginners, or inexperienced users from riding at full power. Technically, the machine is capable of significantly higher speeds with 325 HP and an optimal pitch impeller.
What is an SCOM? (Speed Control Override Module)
A SCOM (Speed Control Override Module) is an additional module that remains permanently connected to the vehicle and overrides or manipulates the GPS signal for the control unit so that the limiter is no longer active. The concept is simple, but it has a crucial disadvantage: The module must remain permanently connected. If it fails or is removed, the limiter will become active again. In addition, a permanently installed module may be visible when selling the vehicle.
The M-JET Vmax Remover – the advantage
The M-JET Vmax Remover takes a different approach: it is not a permanently installed module, but an unlocking tool. This means:
- The tool is connected once and the unlocking is performed.
- After that, the tool can be removed again – no permanently installed module
- Nothing visibly changes on the vehicle itself
- The unlocking remains stored in the control unit unless a vehicle reset is performed
- No dependence on additional hardware in continuous operation
Technical background: How does the M-JET Vmax Remover work?
The M-JET Vmax Remover communicates directly with the Sea-Doo 325 HP's control unit via the diagnostic interface and deactivates the logic that activates the GPS limiter. It is a software-based intervention at the ECU level – not a hardware module that remains permanently in the wiring harness.
For which models is the M-JET Vmax Remover suitable?
The M-JET Vmax Remover is compatible with the following Sea-Doo models:
- Sea-Doo RXP-X 325 (all model years with 325 HP engine)
- Sea-Doo RXT-X 325 (all model years with 325 HP engine)
- Sea-Doo GTX Limited 325 (all model years with 325 HP engine)
What does removing the limiter actually achieve?
With the GPS limiter deactivated, the vehicle travels at its true maximum speed – typically between 115 and 130+ km/h, depending on the impeller, riding weight, and water conditions. Especially in combination with an adjusted impeller or stage tuning via M-JET Flasher, the result is impressive.
