About remapping
The Sea-Doo RXT-X is a personal watercraft and accounts for 5 files in our catalogue, dominated by the 1.5 litre supercharged three-cylinder petrol with a 1.6i also present. It is the top performance model of the range.
Stage 1 makes up 4 files — a completely clean profile with no maintenance work at all. The ECUs are ME17.8.5 and MED17.8.5. On marine engines we always work to conservative criteria.

What do you aim for on a personal watercraft?
Sustained delivery under constant load, which is how these engines actually work on the water. We are especially conservative here.
How does it differ from the RXT entry?
The X is the higher-output version. Our history records them under separate designations, worth checking both.
Does it affect the warranty?
It may affect the manufacturer's cover. We keep the original file so the work can be reversed if needed.
