As you can tell, I'm very new to boating, so any help is soooo welcome. I have a 87 bayliner with a 85 force. The bottom of the boat, (the very bottom), fills up with about 3-4 inches of water when we are out on the lake. It is usually when we are going and then stop. There is a tube in the bottom that the water seems to kinda go out when we get going, but then if we stop, it comes back in. It seems like that is alot of water coming back in. There is a bilge pump switch on the dash by the steering wheel, when should I turn that on? And when should I turn that off. We read the whole manual on the boat, but it wasn't much help. We would like to take the boat back out, but are kinda leary...any answers would be great, Thanks so much, Shane
