What is inside the toon?

[nubutlernin]

I noticed that I had a bit of sloshing in one of my toons, and assume that there is some water in it. I have 3 separate plastic plugs on top of the toons, one front, one middle, one back. Theoretically, leaving them open, when it is hot, should allow for it to evaporate, but probably not quick enough.
I tried to put a small tube in so I could pump water out, but there is something blocking the tube from going down very far.......keeping me from getting to the bottom...some sort of support? If so, is it solid, or if I keep moving the tube around, should I eventually find a way down?

I had a similar issue with my pontoon. Took on water from on the top of the pontoon where the toon is welded to a support bracket (small crack in the weld). Put a small tube into the access hole which is designed for this purpose. The tube only went in an inch or so. Needed a smaller tube yet and wiggled it around and it found its way in. Got about 2-3 gallons of water out. Try a smaller hose/tube

What type of pontoon and pontoon logs do you have? There are variations of pontoon logs. Some U shaped toons have a foam in them. Ideally, it sound like your toons have 3 chambers...hence the 3 plugs. Are you sure you are checking the right chamber?

I am still new to pontoons, so not sure on the toons, but I only tried the back chamber, as it seems to sit lower in the water......this side, however, does have the gas tank right over it, so I would assume that will keep it lower in the water as well.

if you have water in the logs, most likely the weld where the M brackets are has a crack.

to get the water out, normally feed a weighted section of tube to the bottom. you need something heavy enough to go to the bottom. most tubes have a natural curl and will not go vertically down

from there, pressurize the log to 2-3 psi and water will come out the tube.

at the same time, use soapy water to find the leaks and have them welded.
