Make sure it floats...IE: No holes in the bottom
Make sure the motor runs... IE: No knocking or weird noises!
If it is on a trailer, make sure it rolls OK
Finally if you have 5 or more kids, you maybe cramped!
All kidding aside, Welcome to CSC.
The only issues that are a main concern are the brass scupper tubes
that drain out the bottom. Check transom, jump on cavitation plate and
look for any flexing...
If you are not sure about anything else on the boat, just ask!
Take pictures and post any concerns.
