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



Protocol pack for KESS3 Slave covering boats and jet-skis, including OBD, Bench and Boot modes.
In Slave version, read files are encrypted. The modified calibration map is provided by your reference Master.
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.
As marine activity is seasonal, the Slave version limits capital outlay on a segment that only runs for a few months a year.
A KESS3 device (ref. KESS3HW000) is required, along with a Bench power supply for control units programmed outside the boat.

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

All three formats exist for the Boats/Jet Skis category. This product corresponds to the complete package, highlighted below.
Quick interventions
Sufficient if you almost always work from the diagnostic port, without removing the ECU. Sold for €590.00 excl. VAT for Boats/Jet Skis.
Bench Processed ECUs
Needed for cloning or the most secure ECUs. Sold for €390.00 excluding tax for Boats/Jet Skis.
OBD + Bench-Boot: this product
The most common choice to avoid having to repurchase a second protocol later for Boats/Jet Skis.
Activation is performed remotely on your KESS3 Slave unit, 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 each mode can be ordered separately or as a pack. You can upgrade your KESS3 Slave as your business grows.
No, this is a software extension: it requires an Alientech KESS3 Slave unit that you already own and have activated.
This pack brings together both: you don't have to buy the OBD protocol (€590.00 excl. VAT) and the Bench-Boot protocol (€390.00 excl. VAT) separately for the same category.
This is the equivalent of this protocol, but extended to all vehicle categories (Cars/LCVs, Motorcycles/Quads/UTVs, Agriculture/Heavy Goods Vehicles/Buses, Boats/Jet-skis) for the chosen mode.
The content of the protocol (vehicles and modes covered) is identical; only the product reference changes depending on your device's version.
