Engine Control Unit (ECU)

The 16 bit onboard ECU (engine control unit) precisely controls the fuel injection and ignition timing for optimal engine performance.

Electronic Fuel Injection

The Tohatsu 25 and 30hp outboards now have the industry's first battery-less electronically controlled fuel injection that provides quick throttle response, excellent fuel economy, and smooth operation throughout the rpm range.

Tuned Intake Manifold

The tuned intake manifold provides increased low & mid speed torque and quieter operation.

Tubular Air-Intake

The tubular structure of the air-intake, originally developed by Tohatsu, helps to take in necessary airflow to the engine while preventing water from entering into the motor cover.

Through-The-Propeller Exhaust

Through-the-prop exhaust greatly reduces engine noise for a more enjoyable boating experience. This feature is standard on all Tohatsu outboards 4hp and above.
