About remapping
This entry groups Mercury MerCruiser marine engines, with 6 files in our catalogue, spread across the 2.8 and 4.2 litre diesels and the 5.0 and 8.2 litre petrol units. These are inboard engines for recreational craft.
Stage 1 accounts for all 6 files — a completely clean profile with no maintenance work at all. The ECUs are EDC16C39 and an ECM0402 reference. On marine engines we always work to conservative criteria.

What do you aim for on a marine engine?
Sustained delivery under constant load, which is how a boat engine actually works. We are especially conservative here.
How does it differ from the MerCruiser QSD and Cummins entries?
They are different engine ranges under the same marque group. Each has its own entry in our catalogue.
Does it affect the engine's warranty?
It may affect the manufacturer's cover. We keep the original file so the work can be reversed if needed.
