Water enters into where the passengers sit (deck? I'm not sure what it is called) Underneath where the driver sits there is a hole that goes to the back of the boat. A drain for when water enters where we sit. When I slow down after flying around water rushes through the hole beneath my feet. When I take off again most of it drains out. Is there some sort of drain plug or diaphragm that should be there? I just bought the boat and the body seems to be missing some things. The engines are in great condition and the boat runs great! Thanks in advance for any answers.
