During the Mercury Verado Experience days in 2013, held in the Netherlands near Zwartewaal, our BoatTrial crew was invited by Mercury to test several Verado engine models. The Verado series starts from 150 hp and goes up to 350 hp. During our trial, three power rates were tested. A 175 hp Verado installed on a Numo 650 console boat, a 225 hp installed on a Brig 645 rib and a 300 hp installed on a Valiant 750 rib. This somewhat limited but widely used engine range in combination with conventional and modern
boat models gave us the ability to measure some performance parameters. The test runs were performed on flat water. A new Karnic console boat with 225 hp and a high performance Techno Hull SeaDNA rib 999 which is equipped with two 225 hp Verado outboards were part of the range of vessels during the testing days. Even boat enthusiasts and customers had the opportunity to experience the power of a Verado aboard one of the vessels in a relaxed atmosphere.
The Verado outboard-engine family is the only serie-build engine with a standard compressor Boat test in 2013
Mercury Verado multitest
Verado supercharged Verado outboards still appear to be the only series-built engines which are standard equipped with a compressor or supercharger. This results in a greater volume of air in the combustion chambers which, in combination with the additional cooling of the compressed air, leads to a particularly more efficient combustion and excellent performance. A while ago the challenge for Mercury was to design the perfect outboard, which led to the birth of the Verado concept. During the development everything was questioned. High reliability, excellent performance, low fuel consumption and reduced noise were the important topics when building this concept. The smaller Verado models from 150 to 200 hp have four-cylinder four-stroke engines. The larger power rates from 225 to 350 hp have
six-cylinder four-stroke engines. Not only includes the Verado concept engines, it also formed the base for a new electro-hydraulic control system, as well as a digital throttle and shift system called "Smart Craft."
