BREAKING: Mercury’s New V10

Editor-at-Large Charlie Levine reports from Lake X on Mercury’s new line of modern, light-weight V10 outboards. Learn more here and stay tuned for more reporting from his on-the-water testing.

Quiet. Smooth. High performance. Those were just some of the buzz words used to describe Mercury’s industry-first V10 outboards, the new 5.7L 350- and 400-hp Verados.

According to Mercury, the new V10 engines run 45-percent quieter at cruise while delivering high-end performance across the entire RPM range. Mercury now offers outboard engines in V6, V8, V10 and V12 configurations. At a media unveiling, the company said the V10 outboards are a product of Mercury’s continued investment in R&D and production capacity to keep up with robust customer demand. The company has invested $2 billion since 2008, and its manufacturing footprint has expanded to more than 3 million square feet.

“At Mercury, we’re never done,” said Chris Drees, Mercury Marine president. “We have continual new programs being developed.”

To help boaters power their air-conditioning and onboard electronics, Mercury designed the V10s to support an onboard battery system that can do away with the need for a genset. The V10 outboards come standard with a 150-amp alternator that will quickly charge onboard batteries. They will also be offered with an optional dual-mode 48V/12V alternator to pair with Navico Group’s Fathom e-power system, an integrated lithium-ion auxiliary power management system designed to power all of your systems without a generator.

“This engine turns any boat it’s on into a high-performance boat,” said Brunswick CEO David Foulkes.

Weighing 695 pounds, the V10 engines have the same 26-inch mount spacing as the V8 outboards to suit current boat designs that call for trips or quads. At the core of the new engine is a naturally aspirated powerhead. It leverages class-leading 5.7L displacement and a quad-cam design for power, top-end speed and acceleration.

A hydrodynamic gearcase turns the new Revolution X propeller for better fuel economy and lift. Larger diameter and wider blades combined with the deep ratio of the new gearcase should provide excellent handling, acceleration and efficiency from low speeds to wide-open throttle.

The V10 Verado engines are compatible with a new Mercury electric steering system for multi-engine configurations that enhances steering responsiveness, simplifies rigging and, according to Mercury, a more than 50-percent reduction in energy consumption.

“We challenged our engineers to improve acceleration and overall performance with the new V10 Verado outboards, while also making them quieter and lighter than competitors’ outboards in this horsepower range,” said Tim Reid, Mercury Marine vice president of product development and engineering. “Once again they exceeded expectations while also incorporating technologies that make boat operation and maintenance intuitively simple.”
