Raw water intake tee fitting for ballast sytem

[h2oslider]

I was wondering what size everyone is using for the tee off of their raw water intake to fill their ballast. I currently have a barbbed 1 and 1/4 in with a threaded tee to 1/2 inch. What sizes are you guys using that have a similar system?

And also would I be wrong in using a 2000 gph pump off the water intake or would it be better to use the 1100 gph so I don't "starve" the engine?

Thanks,

Paul

I don't know about the other stuff but as for the pump you can always kill the engine when you fill the ballast anyways.
