The Large Shower Sump Pump Systems Mk2 with 800 GPH max flow rate delivers the performance you want on your boat! This Sump Pump is for those needing additional capacity over the standard system box that offers 500 gph performance. 

The lid snaps in to allow quick installation (and removal for cleaning) and includes a gasket to seal the sump box against overflow. The standard sump box includes an air vent to prevent air locks. 

Mk2 Sump Pump Systems meet or exceed all applicable standards of the ABYC and USCG.
