Solid Power for Your V6
At Tampa Marine Tuning, we are excited to offer Outboard EFI's performance tune for 6 cylinder Suzuki outboard engines. With this performance upgrade, your 200, 225, or 250 horsepower engine will increase 25-75 horsepower depending on the model.
- DF200AP +25/75hp
- DF200T +50hp
- DF225T +50hp
- DF250T +25hp
- DF250SS +25hp
- DF250SS (digital) +75hp

The rev limit also increases by 300-400 RPM to help reach higher top speeds and extract as much performance as possible.
NOTE: To achieve optimal performance, your engine must run on minimum
89-90 USA grade / 95-98 AUS/EUR grade octane fuel and adhere to
recommended service intervals. Failure to do so may result in decreased
performance and could potentially damage your engine.
