Designed and built for all out competition. Our new RD-1 drive is completely machined out of aircraft grade aluminum for strength and light weight. Every facet is adjustable. The Uni-Mount is a one piece transom bracket that offers multiple adjustment capabilities for both the drive and rudder mount bracket. Our new machined rudder features a 2-1/2 inch offset that can be mounted either left or right of the drive. The water pick up is machined in the rudder on both sides to ensure positive water pickup. The drive body is fine tunable with an adjustment screw, and can be removed in seconds to grease the drive cable with one screw. When reinstalled it will be in the identical adjusted position. We are offering this complete system natural aluminum (anodized for a small up-charge). Each system includes a rudder, rudder arm, rudder bracket, drive body, 1/4 inch prop shaft, 18 inch adjustable cable with square end, prop hub, thrust washers, 12 inch prop tube with Teflon liner. Made in the U.S.A.
