hour, and with equal execution when skiing at 30 mph. We didn’t leave out the simple joy of skimming across the surface from
10 mph to 45 mph with the same level of quality performance. The MV8 provides the kind of horsepower necessary to plane
with pulse-pounding quickness while equally ensuring the reliability and smoothness necessary for just-above-idle investigation
of interesting coves and shorelines. It’s all here.
The MV8’s heritage extends back to the company’s founding in 1983, when Swiss-born Mario Illien and British native Paul
Morgan sent a handwritten letter to American businessman and team owner Roger Penske. The duo proposed a new company
that would design and build turbocharged engines for race cars. Penske was intrigued and within three months ILMOR Engi-
neering was born.
Working with various international companies over the years, ILMOR has enjoyed unparalleled success in many forms of
racing, particularly Formula 1 and Indy Car racing. In fact, partnered with Honda, ILMOR is currently the sole provider of
engines to the Indy Car circuit.
Since 2004, ILMOR’s marine division has enjoyed
substantial growth, becoming a well-established sup-
plier in the U.S. and European high-performance boat
market. In addition to the MV-550 V-10 engine, ILMOR
has added two more packages: the MV-625 in 2005, and
the MV-710 in 2006. The 700-horsepower, naturally-as-
pirated marine engine was developed with significantly
improved fuel efficiency and a light-weight package, fac-
tors that would add to the superiority of the MV8 in its
development stage.
In 2009, ILMOR had to utilize its substantial engineer-
ing expertise to create an entirely new generation of MV-
10 marine products. Emissions requirements established
by the California EPA (the most stringent in the U.S.)
and the federal Environmental Protection Agency meant
that all high-performance marine engines had to meet
tough new exhaust emissions standards. The MV-650 and
the MV-725, along with state-of-the-art ILMOR elec-
ILMOR Marine, LLC, is pleased to welcome you to boating
enjoyment available only through use of the extraordinary MV8
engine. ILMOR is a recognized leader in the marine industry, hav-
ing originated through championship-caliber, high-performance
engines. Our experience inevitably led to the development of the
MV8, offering 5.7, 6.0 and 6.2 liter versions, which provide the
appropriate power range for ideal wakeboarding at 18 miles per
