We are a club with a recently purchased 2000 Catalina 34 MK II, previously owned by a husband and wife. The 12-gallon holding tank is being replaced with a 30 gallon tank, more suitable for club operations. Repositioning the macerator pump in the limited space available is problematic. We see on bulletin boards that others have had trouble with infrequently used pumps that are below the water line and constantly subjected to trapped seawater exposure on the through hull end and black water exposure on the pump inlet end. We are considering eliminating the pump and over board discharge capability. This would limit the boat to marina pump outs which is our usual operation in any event. We think the minor inconvenience of not being able to pump out when outside the 3 mile limit is something we can live with. Close offshore operation occurs less than once annually. Is there any safety or practical reason why we should not eliminate the macerator and overboard discharge capability?
