Mercury Marine debuted two new outboards, each based on its unique 5.7-liter, V10 outboard engine platform. Mercury Marine President, John Buelow, introduced the two new outboards to the North American press corps at an event held in Tampa Florida, on July 21, 2025.

“Our relentless, continuous product development pace, continues,” said Buelow, introducing the new V10s to some 20 marine journalists in attendance at the Westin Tampa Waterside.

Boating deployed a team to sea trial the new V10 outboards aboard a variety of boats, and in a variety of configurations, provided by Mercury. A full report from that testing will appear soon.

The new 425-hp V10 Verado is said to cost about  $1,500 more than the V10 400. More specific pricing and specifications will be published in a follow-up report.

The new Mercury outboard engines are available now, according to Mercury. The 5.7-liter V10 Verado line now consists of three models:  350-. 400- and 425-hp outboard engines.

Below is the official press release from Mercury Marine, containing key data points.

Mercury Marine, a division of Brunswick Corporation, today announced the latest expansion of its award-winning Verado outboard lineup with the introduction of the all-new V10 425hp Verado outboard and a performance enhanced version of the V10 350hp Verado outboard.

Both models set new benchmarks for performance in the high-horsepower outboard segment, delivering exceptional power, acceleration, and fuel efficiency while continuing Mercury’s legacy for smoothness and quiet operation.

“These new V10 Verado engines reflect our commitment to giving boaters exactly what they’ve asked for: greater performance with the same smooth, refined experience they expect from Mercury,” said John Buelow, Mercury Marine president. “With this launch, we’re raising the bar in the high-horsepower category and reaffirming the Verado family’s position as the pinnacle of premium outboard performance.”

All-New V10 425hp Verado

The new 425hp model delivers class-leading acceleration and significant weight advantages compared to a 450hp competitor. In Mercury’s testing, it was:

• 3 seconds faster from 0-30 mph than a 450hp competitor (on a 26-foot, 5,000-pound center-console boat with a heavy load)
• 254 pounds lighter than a 450hp competitor (25-inch XL models)
• Equipped with a 150-amp alternator – the highest output in its class
• 22% quieter at cruise than a 450hp competitor

The upgraded 350hp model delivers impressive improvements in top-end speed and mid-range acceleration:

• 2.7 mph higher top speed than a 350hp competitor (light load test configuration)
• 4 seconds faster from 0-30 mph and 17.8 seconds faster from 0 to top speed than a 350hp competitor (heavy load test configuration)
• Four times the alternator output at cruise compared to a 350hp competitor
• 40% quieter at cruise than a 350hp competitor
• 15% quicker 0-50 mph acceleration than Mercury’s current 350hp model thanks to enhanced mid-range torque
