Devil boats, the engine should be bolted to the transom using the two top holes. Tie a rope to the rib in your boat under the hand grip of the Surface Drive and put a loop in the rope. Slip the loop over the handle to hold the engine in a neutral position while the handle is in its lowest position. - Page 8 This procedure will hold your boat as tight as any boat strap and will secure your Surface Drive so it will not bounce when trailering. We also recommend that you tie a red flag to the tail end of the Surface Drive when towing your boat down the highway.
