Thanks for the replies fellas - I looked up Fake-a-Lake and found it for $43.90 here:
Do you just hook a garden hose to the other end and let her eat? Also.... where did you all put the suction end? I guess my real question might be where do the ballast pumps take their suction at? Is it a common suction header on the bottom of the hull? I know the overflow lines are above the water line since I can see them while I'm filling the tanks on the river... Sorry in advance if this is a n00b question!
