AR195: Exhilarating wakesports fun. Yamaha's renowned internal propulsion system is not only reliable and fuel-efficient, it also offers the highest level of freedom achievable on the water. The concept is simple: Water is pulled through internally housed propellers and pushed out through marine engines with high thrust points. This technology eliminates the need for an exposed drivetrain, allowing Yamaha boats to plane quicker with less bow rise. The minimal draft makes navigating shallow areas easy. But the benefits don’t end there - internal propulsion eliminates the need for a bulky engine hatch, opening up an expansive swim platform where family and friends can relax close to the water.
