FourStroke

Features


Fourstroke Advantage


Go Farther
Advanced Range Optimisation by Mercury Marine uses closed-loop fuel control to precisely adjust the fuel mixture and deliver the best possible efficiency.
Lighter by Design
Ounce by ounce, Mercury engineers cut kilo's from the FourStroke outboards, ensuring each engine is the lightest in its respective class.
Keep It Steady
Adaptive Speed Control maintains engine speed (rpm) regardless of load or condition changes – such as rough water, tight turns, tow sports and lower speeds on plane – without having to frequently adjust throttle position, a first for the outboard industry.
Smart Charging
Idle Charge battery-management prevents boaters from draining their batteries while operating multiple electronic devices. When battery voltage is reduced, the engine will automatically increase idle rpm to boost alternator output and recharge low batteries to the proper level.
