Edson's Stuffing Boxes combines a rudderpost bearing with an above-the-waterline stuffing box for rudderpost sizes ranging from 1" (2.5 cm) diameter to 4-1/2" (11.4 cm). We recommend fiberglassing the stuffing box/bearing to the top of the tubing when the rudderpost is in place. This can be done easily using alternating layers of fiberglass mat and cloth. This makes the post a structural bearing and will help carry rudder loads with minimal friction. Custom sizes are available on request, but allow additional time.
