Head Maintenance - Drain and Pump Replacement - 2004 Maxum 2400SE
The head on the 2400SE needed some work and with the boat put away for a few months I decided I was going to replace the bad parts. When I bought the boat the head pump would not fill from the seacock and the shower drain was rotted away. I dreaded changing it out but it ended up being super easy. Once I removed the fridge I was excited not only to see the easy access but to also see access to all of the wiring and other fittings that I thought were sealed in the bulkhead.
I am actually going to leave the fridge out for a month while I run spotlight wiring and make a small berth cabinet where the AC would have gone. There is even an extra set of wires prerun for some optional accessory. I might even get rid of the fridge and figure out an ice chest on a slide in rack.
So, whether you are replacing the fridge, plumbing, drains or electrical the steps are similar:
4 screws to remove the fridge (cut DC wires and unplug 110)
2 hose clamps to remove the old hose and elbow
Clean and prep new/old parts
Install new strainer/drain and have a beverage
The toilet pump was also easy too:
Unhook white and black hose
Unscrew large outlet flange (optional: leave flange and hose assembled)
Unscrew four base screws
Replace unit and base gasket
Connect it all back up
