Take to the water with the confidence to power through anything. Tournament-tested, the rugged mount on Riptide SM resists corrosion and performs with flawless reliability. When stowed, the SM mount won't budge, flex or vibrate. Galvanic corrosion occurs when two dissimilar metals come into electrical contact through saltwater. Riptide fights back with a sacrificial zinc anode, a composite shaft and properly balanced materials that are close in electrical potential. The result is a motor that's completely protected from saltwater's destructive forces.
