Mercury Marine, which made major waves in 2021 with the introduction of a V12 600 hp outboard, has debuted the industry’s first V10 outboards in the form of 5.7L 350 and 400 hp Verados.

Mercury expects the new V10s to match a wide range of applications from large saltwater center consoles to freshwater pontoons and single-engine fishing boats. The naturally aspirated engine weighs 695 pounds and offers the same 26-inch mounting space as the company’s V8 outboards to maximize compatibility with current boat designs.

The V10 Verados, which replace the current 2.6L L6 supercharged Verado platform in the company’s lineup, maintain compatibility with SmartCraft technologies. Mercury also offers an optional dual-mode 48V/12V alternator to pair with the Navico Group’s Fathom e-power system, which eliminates the need for an onboard generator. The V10s feature an all-new gearcase and are paired with a new large-diameter Revolution X prop.

In company testing at the Mercury Noise, Vibration, Harshness Technical Center, the outboards delivered quieter, quicker performance than their competitors, Mercury says. The engines deliver full performance with 87-octane fuel and employ a closed-loop fuel system and Advanced Range Optimization like the V12. Also like its larger cousin, the V10s feature a 150-amp alternator to quickly charge onboard batteries and support the vessel’s electrical system.
