I am looking to purchase a 16 foot jon boat with trailer for $500 it has never been registered and I will purchase from original owner. She will include bill of sale with everything. it needs soe work. My question would be is it worth getting it will be my first boat. I am concerned about potential problems with it being so cheap. She said it floats but hasn't been in the water in a long time. Has been stored outside uncovered.Any tips and advise would be greatly appreciated. What all should I look for?
