Mine has a hole cut out at the back of the boat with bilge pump attached to it as well. For filling up while idling out since the transom pick up is used at faster speeds.

For those considering ballast tanks, they can make a difference. However, note the lever arm, for example: water @ 6.5# x 20 gal. = 130 # (not much until 130# is multiplied by distance from transom, say 25', then the fulcrum sees 3,250 # which may be enough to stuff the bow.) Or, it can be argued the measurement should start @ CG centerline, not transom. The two can get confusing because one is a running Force and the other is static force.
