new owner of 1971 19' Bieselmeyer Jet boat

I have won on a auction a 1971 Jet boat, comes with a brand new 550HP 460 Ford, and Berkley jet drive. I am very new to this arena and to say I am ignorant of the "jetboat subject" is saying it nicely. I got the boat with a trailer that has lifetime tags. From the pictures I have seen, everything is in perfect condition. Zero rips or tears and all gel coat looks flawless. I really have no idea what to be looking for when the boat arrives here @ the house in 5 days. Can you members offer any advice? Thank you, Nick
