Sea Sure rudder fittings are precision-machined, tough, reliable and lightweight. Both pintles and gudgeons are manufactured from a heat-treated corrosion-resistant aluminum alloy with black anodized finish for complete protection. Precision machining and optional low-friction carbon bushes eliminate undesirable play in the rudder system. Pintles are cross-pinned for added rigidity and absolute security. Spare bushes (Part number: 18-39) are available for gudgeons.
