Made from 6061-T6 aluminum with a machined finish. The prop shaft seal is
approximately 2-1/4" diameter by 2 1/2" long.
Inside the aluminum housing is 3 double lip cup seals to keep the water out
and a grease zert on the outside body to grease the seal. It's held in the
aluminum housing by a snap ring for safety. A standard size 1 3/4" hose
fits from the rear. Added rounded grooves to help the hose clamp
bite into the housing and not slip off.
