Riptide motors are impervious to saltwater's corrosive effects, thanks to premium-grade marine alloys and aluminum upper arms. Metals undergo a rigid multi-step cleaning process before being anodized or coated with a special zinc dichromate armor plating. All components are then finished with a durable 5-mil TGIC polyester, powder coat paint. When it's all done, you're left with unequaled corrosion protection. Pound for pound, our composite shaft is stronger than steel. It flexes on impact and won't break, kink or corrode.
