300 FourStroke V8 Mercury

Reliability, flexibility, power and efficiency – all within your reach. Backed by decades of marine power innovation and product leadership, Mercury V8 and V6 FourStroke outboards deliver legendary performance and forward-thinking technology. FourStroke outboards are built for any body of water and a wide variety of boats.

Intuitive, Innovative Features

Adaptive Speed Control

Adaptive Speed Control maintains a desired rpm regardless of changes in load or conditions without adjustments to the throttle lever position – a first for the outboard industry.

Smooth and Quiet

The V8 and V6 FourStroke engines are quieter and smoother than the leading competitor.

Easy to Maintain

The exclusive Top Cowl Service Door simplifies routine maintenance, letting you check or add engine oil without removing the top cowl. An hour-based maintenance schedule decal is located under the cowl, providing a quick overview of routine maintenance.

Industry-Exclusive Battery Management Technology

When battery voltage is low, engines will automatically increase idle rpm to boost alternator output and charge batteries to the proper level, protecting batteries from draining while trolling and operating electronic devices.

Ample Charging Output

FourStroke models feature a robust alternator that delivers 20 amps net of charging power at idle and 30 amps

Quick Acceleration

The high-displacement, quad-cam design of the V8 and V6 FourStroke powerheads generates plenty of torque, especially at mid-range.

Superior Fuel Economy

Advanced Range Optimization improves cruise-speed fuel efficiency by automatically adjusting fuel delivery so seamlessly the operator won’t feel or hear it.

Light and Compact

Mercury V8 and V6 FourStroke outboards are the lightest in their respective class by at least 10 pounds and mount on 26-inch centers for broader fitment.

FourStroke Advantage

Go Farther: Advanced Range Optimization by Mercury Marine uses closed-loop fuel control to precisely adjust the fuel mixture and deliver the best possible efficiency.

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.

Lighter by Design: Ounce by ounce, Mercury engineers cut pounds from the FourStroke outboards, ensuring each engine is the lightest in its respective class.

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.
