How do the pump can go backward?
I can not understand why you modify this pump to make an helix propeller. I think  that is more simple use the pump like a jet-pump-propeller (whitout tuning work). Please teach me.

 this is a one way bilge pump, it is made to pump water in one direction only, hence why i cut the housing off and attached a prop so i could make it work both ways

What brand of water pump are you are using? I like the sleek design of those pumps over the bulky box shape of the ones I am finding.
