Gekko chose Indmar for their engines so you'll be getting solid, reliable performance every time. With sport in mind, the Revo has impressive ballast numbers that will really sink the hull for surfing and riding. 900 pounds of Sub-floor ballast is standard and it's upgradable to over 2,000 pounds with bags. It also has a built in trim tab to dial in the wake's attitude. And finally, the Revo 6.7 has a unique look that includes the swim platform in the fiberglass, so the whole boat flows from bow to stern and looks great on the water.
