Damn... 2 Mercury Racing 450's on that small tunnel that thing must hit 140 mph, what a incredible ride for any of us speed demons and the only thing wrong is the motors are 4 strokes, not 2 strokes. The sound of 2 Mercury Racing 2.5l's screaming 2 strokes at 7500rpm is enough to make the hair on your neck stand up in amazement. No outboard motor will ever sound better than that... Awesome.
