I am a pontoon boat aspirant and have not owned one before. I a found a beautiful 2018 Bennington 208 SF for sale that fits most of the features I am looking for. I was told by Suntracker expert to check the toon pressure before buying. I don’t see any plugs on the toons, is that normal? The owner seems to have taken good care of the boat and the toons are still nice and shiny with minimal scratches. I am wondering how will I know if the toons are good and if it has any water inside. Also if it ends up having any water (sloshing inside) , how can I remove it? Any advice will be greatly appreciated. If it checks out, I am buying the boat.
