FourStroke 50 EFI: Engineered for Boating Excellence

New levels of fuel efficiency and fun

Buying a mid-range Mariner four-stroke means you’re buying more because our 60, 50 and 40 hp motors also feature proven electronic fuel injection which offers renowned fuel efficiency and smooth,  quiet operation. For added durability and push, Command Thrust models feature a taller gearcase and 33% larger components. Just the job for bigger boats. Naturally, all these outboards are SmartCraft-ready and are equipped with turn-key starting for fast and reliable ignition. Never has Mariner dependability looked or sounded so good.
