Adda Rudder Steering Extension
Enhanced Low-Speed Maneuverability for Canal & River Use
The Adda Rudder is an essential upgrade for boaters navigating narrow canals or slow-moving rivers.

Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket Adda Rudder, manufactured to meet required marine standards for low-speed steering performance.
How do I know if it is compatible?
The rudder is designed to fit most standard outboard engine legs. It uses a clamp-on mechanism that sits just above the cavitation plate. If your engine leg has a standard profile, this will likely fit without modification.
Can I use this at high speeds?
No. This rudder is specifically designed to improve control at low speeds. It is recommended for use in canals and rivers. Caution should be taken if increasing speed, as the extra surface area can affect handling at high velocity.
Note: Please verify your engine leg dimensions against the clamp design before purchasing. 4Boats / 4boats.co.uk
