when buying a turn key boat always inspect it and it don't hurt to bring a friend with knowledge to see things you may over look.
then have the seller take you out and run the boat ( even if you have to pay a little gas money). if the seller knows you have the money and still wont take you out walk away from the deal. just my 2 cents.
X2 on the test run. Don't buy from anyone who won't take you out for a test run!!!
