Mercury's latest release of the first-of-its-kind V10 5.7L 350 and 400hp Verado outboards is breaking barriers in outboard technology. These new naturally aspirated V10s deliver impressive power and smoothness, unlike other outboards in their class. They are quiet, efficient, and chock full of new technology that is sure to please any discriminating boater. Designed from the ground up as an all-new Verado, these V10 outboards perform unlike any other outboards. Mercury recently released these new outboards to the media at their test facility in Florida known as Lake X. This lake and their R&D facilities on the lake are legendary among boat builders and designers. Mercury has been testing and developing their engines on Lake X since the 1950s, and the latest engines the media saw were a far cry from those running the lake in years past.
