This Seasure rudder gudgeon comes with a 10mm hole and with 3 hole fixings on each side of the straps. All Seasure rudder fittings have 5mm fixing holes and the internal diameter is 38mm.
A 3 hole fixing provides added strength. Seasure transom fittings only work with other Sea Sure fittings as the diameter of the pins & holes are different to that of other manufacturers.
This version of the Seasure rudder gudgeon comes with a bush, once it is worn out you can replace just the bush (18.39) and not the complete fitting.
