High-Speed Transom-Mount The S69, ST69 is the ultimate high-speed transom-mount sensor. The paddlewheel and housing do not project below the hull, which results in minimal spray and drag. Since the paddlewheel does not project below the hull, it is protected from damage by beaching, trailering, or objects in the water.
