My boat is an '88 Tracker Panfish. It takes on a little water in a days fishing now days. Sometimes I let friends and family fishing with me drive my stick steering across the big part of the lake on the way back in.
I'll set in the back and pull the plug while we are running wide open down the lake. This will cause all the water to be sucked out of the bottom of the boat.
I can't never seem to resist the temptation to scoot up to the front, tap them on the shoulder with the boat plug, and say "Where's this go!":D
