Description

Intuitive, Innovative Features

Exceptionally Smooth & Quiet

The Advanced MidSection (AMS) moves engine mounts aft and outward to virtually eliminate vibration. Engine noise is minimised by a tuned multi-chamber air intake, fuel-injector covers that decrease high-frequency noise and a highly engineered cowl sealing system.

Effortless Operation

Verado outboards come standard with SmartCraft® Digital Throttle & Shift (DTS) for ultra-smooth shifting, instantaneous throttle response, as well as electro-hydraulic, automotive-style power steering that provides precision handling.

Joystick Piloting

Joystick Piloting for Outboards offers fingertip control of throttle, shift and steering, so you can dock and maneuver precisely, safely and with confidence. Move sideways, diagonally or spin the boat on its own axis with total control in wind or current.

Adaptive Speed Control

Adaptive Speed Control on V8 Verado outboards automatically maintains the set rpm even as load or conditions change, with no adjustments to the throttle lever position – a first for the outboard industry.

Advanced Sound Control

Change the exhaust tone of a V8 Verado outboard with industry-exclusive Advanced Sound Control. The dual muffler system allows users to toggle between an ultra-quiet mode and a deeper, sportier tone.

Verado Performance Data

Refined Power

V8 Verado outboards generate ample torque from class-leading 4.6L displacement. Supercharged power from the 350 and 400hp L6 Verado outboards delivers instant throttle response.

Superior Fuel Economy

Advanced Range Optimisation on V8 Verado outboards improves cruise-speed fuel efficiency by automatically adjusting fuel delivery so seamlessly the operator won’t feel or hear it.

Quiet & Smooth

The V8 and L6 Verado outboards, both establish an industry benchmark for smooth and quiet operation. The engines are quiet at idle and cruise with significantly less vibration.

Verado Advantage

Legendary Power: The 2.6L Supercharged L6 torque hits the instant you drop the digital throttle. Tuned to power heavy offshore boats out of the hole and over the swell, these engines have the legs to fly.

Smoother and Quieter: Verado engine designs virtually eliminate transmission of vibration to the boat, and acoustic engineering means the neighbors won’t hear you leave, and the fish won’t hear you coming.

Reduced Fuel Cost: Verado outboards deliver superior fuel economy at cruising speed and wide-open throttle. The engine precisely adjusts the fuel mixture and delivers the best possible efficiency at any speed.

Corrosion Resistance: Not only are Verado outboards designed and built to withstand the rigors of saltwater operation, but also they’re backed by a three-year corrosion warranty.
