    Works well. Just make sure the preasure relief can handle the volume. During re-entry the psi/volume spike at the drive is very high. Those little brass reliefs with the incremental barrel adjuster dont work in some applications. The one I have used in the past looks like a 6 inch by 2 inch billet fuel filter. -12 ORB port on both ends. Came pre-set at 20-22 psi. Could get the gauge to go to 25psi on a big air out at a 100 or so. Very effective. Just requires 2 discharge bungs, 1 constant flow and 1 relief. Run them out the side, so you can monitor from drivers seat. Picked up a sandwich bag before.

    One more thing. I remember one boat that had a flow issue at low speeds. Was a combo of the boat type and drive height and the speed at which it began to move water from the drive to the cooler. I think we fixed it by tee-ing to the Bravo pump with a brass check valve and a -6. It would have possitive flow any time the engine was running and would close the check as the drive pressure exceeded the Bravo pump pressure. Lots of plumbing and more bung holes in the hull. But dead reliable. 10 years ago, and by memory, so its just a recomendation and somthing to think about.
