Made from 6061-T6 aluminum with a beautiful machined finish that can be easily polished or anodized to match your existing hardware. They are approximately 2 1/8" diameter by 2 1/2" long.

Inside the aluminum housing are 3x double lip cup seals to keep the water out and a grease zerk on the outside body to grease the seal. The seals are held in the aluminum housing by a snap ring for safety. A standard size 1 3/4" hose fits from the rear, I also added rounded grooves to help the hose clamp bite into the housing and not slip off.

In applications where there is a bad alignment between the prop shaft and shaft log housing we recommend adding one of our fiber strut bushings (1" x 1 1/4") in the rear of the prop shaft seal to aid in alignment. Our prop shaft seals are machined for this application.

Also, while replacing your prop shaft seal, please check out our 1 3/4" Marine Grade Rubber Hose and 1 3/4" 100% Stainless Steel T-Bolt Clamps.
