Water in Pontoon

[poppop]

I heard some water sloshing in one of my pontoons the other day. I shook the boat...and there is water in the left pontoon. There is a plug on top for access, but I understand they are under air pressure. And if water has gotten inside, there must be a hole somewhere that needs to be repaired and the pontoon re-pressurized. Is this something a marina normally handles, or a boat repair shop? Its listing a little bit in the water..but not to bad.

Most have a drain at the back on the bottom. You may want to drain it and try it. I have heard of the threads on the plug leaking. Good Luck

Umm, I don't know this for sure but I have never heard of them being pressurized. Maybe an inner liner but the pontoon themselves. If there is water in it then you have lost pressure anyway. Best I can think to get rid of it if there is no bottom drain would be to get a shop vac and hook up a narrow hose to it to suck out the water or whatever you can get in there to suck it up.

Thanks for everyone's advice. In case anyone else has the same type problem this is what I ended up doing. I took the pontoon to a welding shop. The welder drilled a hole in bottom of the pontoon, let out about 5 gallons of water. He then put a little bit of air pressure in from a cutting torch using the hole he just bored...found the leak on top where the brace was welded to the pontoon. Fixed the leak, welded up the drilled hole. Thanks again.
