Congrats !

Your family will enjoy it !
Now...so it'll stay in good shape, go get that engine's water pump changed right NOW...no matter what the previous owner told you. Just do it.
Then pour a little Seafoam and marine stabil in the fuel tank, according to the directions.
Get a new fuel line and bulb from a dealer. ( ethanol rated)
Replace the winch strap. ( Academy has them)...and add a safety chain to the bow hook and trailer. ( I didnt see one.)
While you're at Academy, get a spare tire.
Grease those trailer bearings too. Take the hubs off and do it right.
If you do all that, you'll have possibly saved yourself a ton of money as well as not having a trip to the lake ruined.
You can thank me later....
( I take cash or whataburgers :))
