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.

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.
