1989 440 SR aft Cabin. It had a "Gray Water" holding tank under the master Cabin Bed. Currently blocked off. Any idea what it was used for?
Additionally, the boat was recommissined with a holding tank and a pump for overboard discharg, no connection to the Aft pump out fitting. I need to install a pump out fitting on the side (do not want to run the 30 feet from the tank to the aft bulkhead.) Any advise is welcvomed on where and how to install the fitting. I am thinking along side the fuel fitting onthe stbd side.
 
"Gray water" is sink and shower drain water, as opposed to "black water," which is water that originated in the toilet. In a few areas of the country, most notably Lake George, NY, gray water may not be drained overboard. Instead, it is held in its own special tank for dockside pumpout in the same manner that black water is pumped out of the sewage holding tank. If you do your boating in an area where gray water may be discharged overboard, you can recommission that tank and use it for whatever application you wish - or even remove it, to free up some storage space.

The pumpout fitting for the tank that you'll be adding, should be on a horizontal surface, either side deck or forward deck, where you have good access to it from the dock, and on the same side of the boat that fuel and water fittings are located - and you should also be able to get at it from inside the boat, for servicing purposes, should anything ever go wrong with it or its connecting hoses.
 
i woudl REALLY avoid installing a pump out fitting too close to the fuel filler... it's way too easy for someone to screw up and pump in gas or diesel in there... in my opinion, fuel, water and pump out fittings shoudl be part from each others... you'd be surprised how some dock attendants can't read simple words like WATER or WASTE...
 
With one proviso; Waste should not be upstream to the water connection because it is too easy to open them at the same time, key in hand and the danger of effulent getting into the water tank.

Thanks all for your comments.
