Jon,
Many years ago I did a similar dump thing bought a boat in an auction on ebay -(near new motor was ten years old with 200 hours on it) and the paint rubbed off when polished, trailer was in good nick but not 1 year old as described - I learnt my lesson from these con artists - The next boat I bought it brand new from a boat show (I now have a Stacer 509 searunner)
