Trailers normally bring good money...
If the electronics in the motor are good...if it has t/t...that stuff will bring some decent money....the cowling can also...
If the lower unit has clean oil in it...and it shifts as it should...that will pay for the boat if you can get around 4-500.
Does it have a stainless prop?? If it does and is good shape you can shine it up with a buffer and some white rouge and get a 100 out of that possibly...75 at least I would say if its not dinged up.
If the boat itself is in good shape...the fiberglass...clean it all out...simple green is one of the best products for this...and you might get a 100 or so out of the hull.
The tank, if its metal...trash it...if its plastic so you can see through it...use simple green and wash wash wash...maybe after the first wash take it to the car wash and really get after it. The set it out and let it dry...once its all dry put some gas in it...slosh it around...all over it...do this a few times and you should be good. If you use the tank yourself...put some stabil in the first couple tanks for peace of mind...but the tank should dry out eccspecially with the gas getting slosh around in after it sets and drys out.
If you can get it for 5 or less I would jump on it...check the lower unit oil first though...if its white you may have a hard time making money.
Just my thoughts
"But if serving the Lord seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord.” Joshua 25:15
