i only have the bravo one stock water pickup, can i add another pick up ? what do you do ?

I would assume you need it for an innercooler?

why ?

No just to get more water in the motor

Do you have the low water pickup only, or high water pickup?

You can chamfer the holes a bit to pick up water pressure. What kind of water pressure are you running right now?

You need to explain you situation more. If you are having cooling issues with your setup it may be something else. if you just want a offshore style pickup thats different.
