The rope can be replaced with any rope that works in the cleat and fits through the tube through the cockpit area. We use 4 mm nylon. Kevlar strengthened produces the best results. If there is a lot of friction in the systemit is often from sand and salt build up in this tube, flushing it through with fresh water can help.
Where the rope enters the boat at the back it can cut a groove into the fitting also making it stiff to use. This groove can be rounded off or replaced with a brass 'Through hull skin fitting' to reduce the friction. The blade and pivot can be removed from the boat by releasing the bungee that is tied to the deck cleat. The parts can then be cleaned, repaired or replaced. This bungee can also be tightened to help pull the skeg down or loosened to help the paddler pull it up. To re-thread the cord and bungee we use a thin strand of wire with a hook in to pull it through. As we don't manufacture these systems anymore we don't stock any of the parts, however these can be obtained from Valley.
