No Sacrifices, No Compromises, No Apologies

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

Effortless Control

Digital Throttle & Shift (DTS) controls deliver smooth, quiet shifting and instant throttle response, with zero hesitation. Advanced electro-hydraulic steering enhances the driving experience at all speeds, providing complete control and confident handling wherever the water takes you.

Smooth and Quiet

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

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.

Ample Charging Output

FourStroke models feature a robust alternator that delivers 20 amps net of charging power at idle and 30 amps total at wide-open throttle.

Exceptionally Smooth & Quiet

A more rugged, more refined next-generation Advanced MidSection (AMS) mounting system cradles the powerhead to isolate noise and vibration, while careful tuning dampens induction sounds and nearly eliminates injection noise. 600hp never sounded so quiet.

FourStroke Performance Data

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 Optimisation 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 5kg and mount on 26-inch centres for broader fitment.
