Dripless prop shaft seal kit that was optional equipment on the Catalina 380, Catalina 387, Catalina 390, and Catalina 42. Designed for 1-1/4" shaft with a 2-1/4" outside diameter stern tube.
A 3/8" ID hose lead up from the hose barb to a point at least 2' above the waterline to burp any air from the shaft seal is needed or you can install a dedicated through hull to provide a fresh flow of water to ensure it does not run dry.
• Shaft collar with two sets of set screws
• Carbon stator with hose barb
• Bellows with two sets of hose clamps
This retrofit shaft seal requires about 7" (6-1/4" when the bellows are properly compressed) between the aft end of the bellows (where they clamp to the shaft log) to the forward surface of the stainless steel rotor. If retrofitting this to an earlier boat, measure to ensure there is enough clearance to accommodate this style seal.
