I Built A Pontoon Boat With A Wood Deck & The Back Of The Boat Sinks! What Would Make It Float?

Water supports the amount of weight that it displaces. Adding foam inside the pontoon will do nothing to make the pontoon support more weight. And weight is your problem. You will be better off adding a whole or partial third pontoon in the rear of the boat or move some of the weight forward. If it was mine, I would however fill the pontoons with foam for safety

Very good thought. I do however, wonder why the fluid would only collect in the rear and not the front, causing the front to sink. Also, is the boat level, side to side, and did the pontoons take on the exact amount of fluid in both.

sounds like a Yankee, Very good use of words, but the guys boat is still sinking. Lets do it Okie style. first is the pontoons empty of fluids? Next, what size of motor are you hanging on it. If it is big and hanging on the, way out there in the back, this could be a problem. A lot of pontoons have a portion of the pontoon behind the motor. You might want to remove the motor for a test and see if it helps. Treated lumber is also heavy when new, but the boat if evenly planked should at least be level. What is the size of these pontoons. Write me and again I will try to help.

Add a drain plug in both pontoons and fill them with a US Coast Guard Title 33 spec foam.
