was wondering where to pull the water from for cooling, was thinking just from drives and a serperate spot for the innercoolers, they have two spots where it pulls water but there where the notched transom is so to me they would get air alot, do u think 1 #10 fitting would supply two inner coolers?

depending on the speed of the boat. but -10 sounds very small. if you do seperate pickups use a seperate strainer with a pop off valve and make sure you have plenty of volume going in. the popoff will help maintain spikes during re-entry and the bleed will kepp the pressure down if your really runin speed.
