Your
75 HP is a
90 HP in disguise
Evinrude used the same engine block across multiple horsepower ratings. The only difference is the programming of the EMM. We reflash it to the higher HP version your hardware already supports.
- No hardware modifications, software only
- Can be combined with a repair in one shipment
- Fast turnaround, typically back within 3 days
Same block, different label
Evinrude built their E-TEC engines around a small number of shared engine blocks. A 75 HP and a 90 HP can share the exact same hardware. The factory simply programmed the EMM differently before it left the production line.
That means if you have a 75 HP engine on a block that was also used for the 90 HP variant, the hardware is already there. The EMM is the only thing limiting it. We verify your part number is on a shared block and reflash it to the higher HP version.
The result is the rated output of the higher model, using your existing engine, your existing wiring, your existing installation. No new parts, no engine work.
Not all engines qualify, check first

From Internet Myths to Master Craftsmanship: Why an Evinrude is Never Finished
Dr. Evinrude & Hardware Care: The ultimate team for every Ficht and E-TEC outboard!
I have been a die-hard Evinrude fan since the 1980s. The simplicity, the raw torque, the fierce acceleration, and yes—even the sound and the smell—are the definition of pure boating pleasure to me. When production stopped in 2000, it truly broke my heart. Now that I can dedicate plenty of time to my passion in my hobby workshop, I help boaters all over the world as 'Dr. Evinrude'.
