What is the GPS Speed Limiter on the Sea-Doo 325 HP?
Sea-Doo equips the 325 HP models – RXP-X 325, RXT-X 325, and GTX Limited 325 – with a GPS-based speed limiter. This limiter activates via the GPS signal and cuts power at approximately 109 km/h (68 mph in the USA/Canada) or around 112 km/h (70 mph) in international markets. The engine itself is technically capable of significantly more – the limiter is a manufacturer-imposed restriction.
Why Does This Limiter Exist?
The GPS limiter is a safety and liability decision by BRP. It is intended to prevent beginners, inexperienced riders, or use in restricted waterways at full power. Technically, the machine is capable of far higher speeds at 325 HP with an optimally pitched impeller.
What is a SCOM? (Speed Control Override Module)
A SCOM (Speed Control Override Module) is an add-on module that stays permanently connected to the watercraft and overrides or manipulates the GPS signal to the ECU so the limiter no longer activates. The concept is simple but has one significant downside: the module must remain permanently connected. If it fails or is removed, the limiter returns. Additionally, a permanently installed module can be visible when selling the watercraft.
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 activation tool. This means:
- The tool is connected once and the activation is performed
- Afterwards, the tool can be removed – no permanent module required
- Nothing visibly modified on the watercraft
- The activation remains stored in the ECU as long as no vehicle reset is performed
- No dependency on additional hardware during normal operation
Technical Background: How Does the M-JET Vmax Remover Work?
The M-JET Vmax Remover communicates via the diagnostic interface directly with the ECU of the Sea-Doo 325 HP and deactivates the logic that triggers the GPS limiter. This is a software-based intervention at ECU level – not a hardware module that permanently remains in the wiring harness.
Compatible Models
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 watercraft runs at its true maximum speed – depending on impeller, rider weight, and water conditions, typically between 115 and 130+ km/h. Especially in combination with a tuned impeller or a Stage tuning via M-JET Flasher, the results are impressive.
