Round Rudder Box 1"

New design. Made from 6061-T6 Aluminum that is machined finish.

Sealed bearing design (just like the billet prop shaft log seals). No more housings to wear out!!! The prop shaft rides on the bearing.

This new rudder stuffing box has a standard 4 1/16” round mounting flange. So it is a direct replacement for your older style stuffing box. No mounting holes have been drilled, because every hull is different and has a variety of hole sizes and patterns. All you have to do is transfer punch the existing hole locations in your hull to the rudder box and drill the size you need.

Fits all standard 1 1/2” diameter thru hull holes. The 1 1/2” diameter section, that goes thru the bottom of your hull long (1 3/4” long), was left to accommodate any hull thickness. You will have to trim to fit.

Overall height of stuffing box inside the boat is 2 1/8”.

Starting from the top of the stuffing box to the bottom features a snap ring for safety to help retain the 1” sealed bearing that is bored a few thousands larger than your rudder shaft.

Next is an ample sized grease reservoir which is filled by the grease zert located on the outside of the rudder box housing.

A double lip grease cup seal is lightly pressed in as a second barrier to keep water out. The first water barrier is a 1/8” diameter o-ring that is below the grease cup seal.
