OK so we all have left forgotten to put the plug IN when we launch the boat. went fishing with a buddy one day. trip was fine. he left to go out of town. calls me couple days later to go an make sure his ball lock is on his trailer. i go over there and see what looked like a boat shaped swimming pool in his yard. we had a few rainy days lately and he had forgotten to take the plug OUT. the 3-4 inches of rain would not be so bad, but when parked right under the eve of the house with no gutters, well presto!! instant pool. drained it and it seems to work fine now.<br /><br />Up side of this, his boat doesnt leak!!!
