Just as nautical horsepower junkies were pining the demise of
the high-powered Seven Marine engines,
Mercury has just announced the production
of the world's largest, most powerful outboard, a 7.2 litre big block,
naturally aspirated, four stroke, quad cam, 600 HP V12 Verado. Among
many design features is a two speed transmission which
automatically shifts between power and high rpm, depending the need.
It also features a hydraulic, wet-clutch transmission (probably
comparable to a velvet drive) which, among other things, makes
the use of the "sky hook" virtual anchor feature almost unnoticeable.
A totally new feature is steering from rotating gear cases; the
engines don't ever move. I realize to many, this is not really
newsworthy, but to gearheads like myself, you might like to
hear about it and take a look...
