Compression test on the motor wont hurt considering its age, also ask about ethanol treatments that have been used during storage, if its that clean it may have set in his garage and not seen very much usage, ask why he is selling it , looks like he is selling a mini van and a Harley from that one pic. Do you have anyone who can go with you that's knowledgeable about boats? The above advice is awesome!!! Just dont let the nice paint job blurrr your vision
