Dimensions: 13.5 in diameter; 25 degree dish; five spoke design. Improved steering control: This marine outboard steering rudder delivers smoother and more predictable turning on the water. At low speeds or during wide navigational changes, it enhances overall vessel control. Smooth directional stability: Designed for consistent performance, it helps reduce drift and oversteer. It provides reliable course correction and better tracking in calm or mildly choppy waters, making it suitable for leisure or fishing use. Essential navigation upgrade: Adds precision to your steering setup. It enhances maneuverability during docking, reversing, or straightline travel, helping you maintain direction with minimal effort or course deviation. Use scenarios: Docking and reversing in confined marinas: improves precision and reduces stern swing for easier control. Slowspeed maneuvering for fishing or closequarters operation: helps hold a steady course with less adjustment. Straightline cruising in calm to mildly choppy water: delivers more predictable tracking for steadier, easier operation. Compatibility and performance notes: designed for marine outboard steering systems to enhance steering response and stability without compromising operation.
