I ended up going with the following set up:
Shurflo 1000GPH(Primary)
Water Witch Electronic Switch(standard model)
Johnson 2200(Backup)
Water Witch Dual output, second sensor turns on high water alarm. Below is a pic. I had to fabricate a mount for the Johnson pump, since the screw holes were in the bottom of the pump filter and I didn't want to screw it into the hull itself.
I know the back-up switch is a little high right now, I will probably bring it down a little bit.
I also got non-corrugated hose(holy $$$ batman!) which will go in after I finish repairing the gunnels and drill another hole for the second thru-hull fitting.
A huge thanks to Dennis(Bushwacker) for all the advice!
Any feedback or comments are more than welcome.
