⚠️ Requires an activated Kess3 Master Alientech device.
This product is a software extension, not a device.



Protocol pack for KESS3 Master covering boats and jet-skis, including OBD, Bench and Boot modes.
Marine remapping covers outboard and inboard engines as well as jet-ski powertrains. Activity is seasonal and concentrated in coastal and lakeside areas, with a leisure clientele that is relatively price-insensitive.
OBD mode reads and writes via the diagnostic port without removal. Bench mode connects directly to the control unit connector. Boot mode connects to specific points on the circuit board. This pack covers all access methods from older to the latest powertrains.
In Master version, read files can be modified in-house or sent to a tuner of your choice.
A KESS3 device (ref. KESS3HW000) is required. On marine powertrains, accessing the control unit often requires removal: ensure a stable Bench power supply is available.

WHAT THIS PROTOCOL COVERS
Please check that the category and mode correspond to your usage before ordering, as the protocol cannot be modified after activation.

All three formats are available for the Boats/Jet Skis category. This product corresponds to the complete pack, highlighted below.
Quick operations
Sufficient if you almost always work from the diagnostic socket, without removing the ECU.
Bench Flashed ECUs
Required for cloning or the most secure ECUs that require bench or boot intervention.
OBD + Bench-Boot: this product
The most common choice to avoid having to buy a second protocol later for Boats/Jet Skis.
Activation is performed remotely on your KESS3 Master device, using your Alientech ID, within 24 to 48 hours after your order.
No: activation is permanent for the chosen category and mode. Only vehicle compatibility updates are covered for 12 months, then renewable.
Yes, each category and mode can be ordered separately or as a pack. You can expand your KESS3 Master as your activity grows.
No, it is a software extension: it requires an Alientech KESS3 Master device that you already own and have activated.
This package combines both: you do not have to purchase the OBD protocol (€1,290.00 excluding VAT) and the Bench-Boot protocol (€890.00 excluding VAT) separately within the same category.
This is the equivalent of that protocol, but extended to all vehicle categories (Car/LCV, Motorcycle/Quad/UTV, Agriculture/HGV/Bus, Boats/Jet-ski) for the selected mode.
The content of the protocol (vehicles and modes covered) is identical; only the product reference changes depending on the version of your unit.
