I have water in my fuel tank. I have used ALOT of water removing additives and it is still there. Whatis the best way to remove the water from the tank without emoving tank from boat? I already have a water seperating filter and I need to change it every three hours of run time or it starts to pop thru carb. Im not apposed to removing tank if need be but if I dont have to I would rather not.

And it never will
First thing you have to do is find out WHY you have so much water. Oring missing or bad on fill cap, vent sucks water in while underway?????? Just to name a couple.
Now, to get the water out of the tank, try this.
First, head to NAPA and get a cheap electric fuel pump. Make and model doesn't make any difference. Pickup some fittings for the pump so you can attach some 1/4" ID clear tubing to both ends of the pump. Then get you a couple of feet of copper tubing that will fit tight inside the clear tubing, and put it on the pickup side of the pump. Make the output hose long enough to go into a container for your junk gas.
Now, put some wires on the pump (a red and black will work..... red for positive and black for negative) put some clips on the end so you can hook to a battery.
NOW, since water always settles to the bottom of the tank, raise the bow of the boat so the back of the tank is lower than the front. The water will also head to the back.
Then remove the fuel pickup tube from the tank (make sure the fuel level is low enough when you start that it doesn't run out of the fitting when you pull it out).
Start your electric fuel pump and stick the copper tube all the way to the bottom, move it around and you will get all the water and leave the gas.

Dispose of the contaminated fuel properly

I have an electric fuel pump so I guess I could fill containers with that. Never thought of that. just hook it up to a battery and let it run
