CORROSION PROTECTION
Combined with our proprietary alloy (YDC-30), our Phaze Five™ electro-deposited paint process provides a five-layer barrier against corrosion. Stainless Steel components such as the drive, prop and shift shafts provide an additional layer of critical corrosion protection. And multiple sacrificial anodes throughout the motor provide protection from the elements.
