Hey Bill et al,
Here, finally, are some pics - in series - showing the boat's new pump board installation.
A piece of leftover 3/8" Lexan with a shelf added to hold the high water Shurflo 1500 8Amp,
and a couple small bronze screws (can't be seen) to hold the screen clip bracket on the small Shurflo 1000 3.75 Amp.
The small pump is mounted on one side and at the very bottom with its hose pointing aft "through" a 'L' shaped hole in the pull-board.
The pump and attached hose can be lifted off and removed from the unit.
The large high water pump is fitted to the board with its hose also pointed aft and held on tightly with a nylon tie.
Assume the small pump to be replaceable - and the large expensive pump never used.
The WaterWitch digital sensors are screwed on to the board with their wires blue taped.
There is no room in the Ariel's narrow bilge/sump for traditional float switches. At least not in what litlgull has behind her ballast.
For the big pump WaterWitch has a high water alarm with a stand alone buzzer and mute fixture not shown.
