This Sump Pump was custom made by DVyss for a Spencer 57. The acrylic lid allows for visual inspection and instant access using 4 stainless steel draw-tight latches.  A check-valve is intergrated into the output and also servers as the bulkhead fitting for a clean installation. This system is common in most Viking Yachts and now availble for upgrades or refits. The Housing may also serve as a High-quality Sea Chest for Baitwell and Washdown systems. Custom variations are possible. Submit an inquiry for more information.
