I don't know why you just don't stop the leak. That has worked every time for me...LOL

Another thing you can do is borrow someone elses bilge pump and connect it straight to the battery. Of course you would have your fast friend getting the bilge pump while you beach the boat on a flat. If the leak isn't that fast once you get the water out you might have a chance to get to the ramp.
