Mercury - FourStroke 50HP EFI
FourStroke 40-60hpHeld to a Higher Standard.There are plenty of good reasons these outboards rule the water. Start with no-worry reliability. More low-end torque for excellent acceleration. Increased fuel economy and outstanding overall performance. Enhanced fuel injection (EFI models) for boosted efficiency. A robust electrical system with a high-output alternator to keep batteries charged and fishing electronics humming. They have everything you need, and nothing you don't. |
High-Output AlternatorAn 18-amp alternator helps keep batteries charged and fishing electronics humming long into the evening bite. |
Command Thrust GearcaseDesigned to sit lower in the water and turn larger props, the available Command Thrust gearcase lifts heavy boats on plane more easily and holds them there at lower speeds without impacting top speed. |
Electronic Fuel Injection (EFI)From the moment you crank the engine to the moment you drop the throttle, EFI technology responds with instant power. Surefire starting in all weather conditions. Smooth, efficient acceleration. Maximum fun. |
Convenient MaintenanceWe made maintenance easier with features like color-coded touch points, an easy-access water-separating fuel filter and an oil filter drip tray, which helps you get the job done with less mess. |
Tiller HandleWith a range of adjustments, ergonomic controls and the flexibility to be set up for left- or right-handed operation, the available advanced tiller puts you in complete command of your adventures. |
Powerful TorqueA high-displacement powerhead generates serious low-end torque to easily power boats on plane. More torque requires less work from the engine, for a longer service life. |
Quick AccelerationThe single-overhead-cam design delivers sporty acceleration and exciting overall performance from midrange through top speed. |
Hard-Working MuscleWith an available Command Thrust gearcase and ample torque, 40 to 60hp outboards make easy work of moving heavily loaded boats. |
