Sierra Oil Seal 18-8326 for Evinrude Outboard Prop and Driveshaft

The Sierra 18-8326 Oil Seal is a round, white marine oil seal engineered for Evinrude outboard prop and driveshaft applications. It seals the shaft bore to keep water out and lubricant in, protecting critical rotating components from corrosion and contamination in the harsh marine environment. Sierra products are built to meet or exceed the original equipment part they replace, and Sierra supplies many OEM engine manufacturers and boat builders with quality parts every day.

This seal measures 29 millimeters on the outer diameter with an 18 millimeter shaft size and a width of 8/12 inch, and weighs 0.03 pounds. Its round shape and white finish are consistent with a compact prop shaft or driveshaft seal designed to fit snugly into its housing bore. Boat owners performing prop shaft or lower unit driveshaft service on Evinrude outboards can use this seal as a direct fit replacement, whether refreshing a single worn seal or completing a full driveshaft or prop shaft reseal.
