Adding A Raw water Wash Down

[macojoe]

Ok I use to do the live well much like phatdaddy, But we had a guy making us a pipe for a rule 500 or 800 that looked like this worked great, I use to have like 10 of these but gave them away as I no use any more.

My last one









Now as for the wash down and possible bilge pump I am thinking of these, I have 2.









As you can see it says self priming to 3 feet, I was thinking of using as bilge cause I have 0 room in the bilge for a pump, what you think??

Then the other will be a wash down, but not sure I want to add a raw water or get a fresh water tank and go that way?
Maybe both and put a switch so I can use both on one pump??
What you think??
