well it seems you know about the floor and the hull and what to test? Don't forget to check the transom!! Lift motor up and grab from the bottom and try lifting and moving side to side. If there is movment then it needs a new Tarnsom.

I like to say I buy the boat not the motor, because IMO they always need work. So it is good that you want to repower down the line.

On motor you will want to check the lower unit oil for water, check the trim motor and all connections for oil leaking, START, make sure it is pumping water!!
This time of year take for water test, This will tell you the best!

Does it have a trailer?? What shape is it in?? Who makes it? A new trailer is a big ticket item to buy!!

$3,900 is a good deal if all is in useable condition!! Just rember, it not unlike a used car! In the way that you should have a few dollars around to fix the small things, they add up!

Good Luck!~! Lets us no what you do!! I am sure others will chine in here and give you more info!
