50 HP
Unlock the full rated output your engine block was built for. We reflash the EMM to the 50 HP version — no engine work, no new parts.

- Model years 2010 – 2020
Why this upgrade works
Same block, different label
The 40, 50 and 60 HP E-TEC twins all run on the same hardware. The 40 to 50 HP step is a pure software change. A reflash unlocks the higher rated output.
