Rudder Washer Set C-310, C-320, C-34, C-36, C-38, C-42

Part #: T1917
Typically used on the rudder shaft in pairs. One above the deck prevents the rudder head from wearing the fiberglass. One below the hull is installed with the beveled side down, toward the rudder. Sealant (the high strength adhesive / sealant shown below) is applied inside the bevel and helps seal the rudder shaft where it enters the rudder blade.
• Inside diameter: 2.9"
• Outside diameter: 3.6875"
• Thickness: .1875"
1) Requires Z2252 high strength adhesive for installation shown below under "May we also suggest".

2) The inside diameter is a bit larger than the rudder shaft. The stainless tubing the rudder shaft was made from will vary from its nominal size from one piece to the next. The rudder washers will fit the largest diameter tubing.

3) Boats equipped with the Rudder Bearing Assembly item #Z2931 typically did not use these rudder washers. Owners of larger Catalinas equipped with a rudder post with an OD of 2.860" have sometimes used these washers as shims to eliminate excess space between the bottom flange of the rudder bearing assembly and the top of the rudder. Be careful that installing a washer in this gap doesn't affect the alignment of any through bolts that pass through the rudder shaft, for example, that which secures the Radial Drive Wheel to the rudder post.
