I have a Sea Sweep for sale that was only used for a few months before my pump died. It was bought as a stand alone unit (i.e. no Tunze pump included). Mounting is for eurobraced tank. The threaded pipe was sliced open in order to accommodate my old Tunze. Buyer can contact manufacturer at [email protected] for the appropriate parts to attach the pump to the Sea-Swirl or to change the mounting. Optional parts are available to attach almost any pump for approx $50.
