Rotax Jet Boat Tuning and Diagnostics

The M-JET Flasher supports Rotax jet boat drives (Rotax JPS) via smartphone, without a laptop or workshop. Tuning is available as a Lite version, optionally for 1 or 2 engines. In addition, you can read error codes and, depending on the model, view live data.

Which drives?

Common Rotax JPS drives with 4-TEC 1503 / 1630 (Bosch ME17.8.5) as well as 900 ACE are covered, installed in many brands from Sea-Doo jet boats to Williams Jettenders.

What does M-JET offer for jet boats?

• Software tuning (Lite) for 1 or 2 engines
• More direct throttle response and more punch
• Read and clear error codes
• Can be reset to series production at any time

Good to know

The app reads engine errors; speedometer and iNR only depending on model and equipment. MG1 control units available on request. You can see which drives are specifically covered directly in the configurator.
