Capable of speeds over 140mph, the Outboard Performance Craft has come a long way since its beginnings as the "Outboard Pleasure Craft" class. This category of racing features some of the biggest, most powerful outboard engines in Powerboat Racing. OPC engines can range from off-the-shelf production engines to heavily modified, high tech engines built for world record speed. Today's most high tech OPC race boats can start from a dead engine start, go 0 to 100mph in 6 seconds and turn 180 degrees with forces of up to 5 G's. These tunnel boats are the fastest turning vehicle in the world!
