I have a 85 31' open. I need to replace the shower discharge hose and I cannot for the life of me find the access to the shower pump. The discharge hose hole that is in the firewall is way too small. Any help would be greatly appreciated.
If the 3100 is similar to my 3200 the shower sump is located in the bilge beneath the cabin steps. You can access through the floor but likely have to remove steps to replace/repair shower sump.
Steps can be removed with about 8 screws.
Which pump are you referring to, the shower pump or shower sump pump? In my 88 3100, the shower pump is run off the fresh water system and the pump is located in the engine compartment on outboard wall area. Otherwise the shower sump pump is located in the engine compartment behind the bulkhead and in front of engine closest to the shower depending on your layout with bathroom on port or starboard. My layout is bathroom on starboard and the sump pump is on other side of bathroom bulkhead in the engine compartment in front of starboard engine with drain hose running through bulkhead to pump.
