1" Shaft stuffing Box, this is the plastic unit with teflon packing inside. Operates the same as the brass style,  however the plastic box does not require large wrenches to adjust, simply pull the cotter pin, adjust by hand, then re-insert the cotter pin. This style is a favorite in our shop. Used in older ski boat with 1" shafts.

Order connector hose separate if needed (1 3/4")

NOTE: NO Stuffing box or any other type of shaft seal will work when a shaft/engine alignment is "off" you must check this annually and adjust as needed!
