The V10 engine is among the automotive world's most unique and brilliant configurations, but with the Lamborghini Huracan Sterrato and Audi R8 GT sounding the death knell for the magnificent tenner, we thought we'd seen the end of it. However, Mercury Marine has introduced an industry-first outboard V10 motor for boating applications that could see it live on a little longer.

The US-based company's 5.7-liter V10 "Verado" outboard is naturally-aspirated and offered in two states of tune; 350 and 400 horsepower. Mercury Marine is particularly proud of the new V10 and says it's the quietest and smoothest outboard in its class. At cruising speed, it's 45% quieter than some competitors.

Mercury will offer the new V10 Verado engines with an optional dual-mode 48V/12V alternator that pairs with the Fathom e-Power System, an integrated lithium-ion auxiliary power management system, allowing owners to abandon the traditional onboard generator.

The Verado engine is also equipped with Adaptive Speed Control that maintains engine rpm, regardless of changes in load or water conditions. This not only makes for a smoother experience at low speeds but also enables boaters to climb larger swells with ease. Thanks to the Transient Spark Technology, the spark timing is electronically adjusted to optimize low-end power.

Rather amusingly, an advanced sound control function enables you to have a more civilized exhaust note or a more distinct and sporty roar at start-up and idle. We doubt it sounds as good as a Lexus LFA V10 at full chat, but it's still a neat feature to have.

It's great to see the iconic V10 in use, even if it's not in a car. Sadly, it seems there's not much hope left for the configuration; Audi is discontinuing the R8 V10 forever, and the Lamborghini Huracan's successor is rumored to debut with a plug-in hybrid V8.

In the future, it seems our best chance of hearing the raucous, hollow howl of a ten-cylinder engine will be at a nearby lake or marina. But, even then, it's not an aural delight that will last for much longer. It's only a matter of time before leisure watercraft goes the same way as the auto industry and adopts a battery-electric setup for most boats.
