The Attwood Tsunami 4663-7 with its 1" NPT is best suited to screw right on top of the ball-valve. If bilge depth is an issue, then use a 90* elbow. This gets the pump vertical, but make sure the pump's outlet is oriented up. Another option is to use a pump like the Rule 1100, which is actually faster in a real world test, and .75" thru-hull and ball-valve. Even though this pump cost more, the price difference between the .75" thru-hull and B/V and the 1" bronze closes the gap. Both the T1200 and the Rule 1100 use a 1.125" outlet, so the same 1" hose can be fitted.
