Small Engine, Not-so-Small Gains
At Tampa Marine Tuning, we are excited to offer Outboard EFI's performance tune for 4 cylinder Suzuki outboard engines. With this performance upgrade, your 40, 50, and 60 horsepower engine will increase 5-35 horsepower depending on the model.

The rev limit also increases by 200-500 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.
