About remapping
The Mercury QSD is a marine diesel engine range and accounts for 8 files in our catalogue, split between the 2.0 D, 2.8 and 4.2 TD blocks. These are inboard engines for recreational and light commercial craft.
Stage 1 accounts for all 8 files — a completely clean profile with no maintenance work at all. The ECU is a single reference across the whole catalogue: EDC16C39. 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 entry?
They are closely related ranges recorded under different marque names. It is worth checking both entries.
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.
