Congrats.
You’d be wise to plan a few failures.
Monitor your wheel bearings on your first road trip. They should not get warm at all.
You batteries could very well be shot, use a Load Tester to check them.
You can run your motor by putting your motor into a tank of water, or by using “Ear Muffs”, You will want to get it to a shop to repair before the shops get busy this spring. Likely you’ll have an issue with the fuel pump diaphragm drying out.
You can check the bilge pump to be sure it is working.
Make sure that spare tire is bolted down well.
Check to be sure you have proper tongue weight on the trailer. You should have 100-200 LBS on the trailer tongue. If it is feather light that is dangerous on the road. You can adjust the boat to sit forward on the trailer if this is the case. Tires look to be way back, which would be proper for a light weight boat.
Sit in the seats and rock, be sure the floor is in good condition and not rotting.
Change the lower unit oil.
It would be wise to replace the fuel line/bulb coming from the tank to the motor. They can degrade over time.
If there is old gas in the tank, find a way to dispose of it and start with fresh no ethonol gas. Be sure to mix properly with oil.
Get insured.
Get licensing.
Check to be sure you have lifejackets and throwables.
Check the trailer lights.
Good Luck. You can have it ready for spring, or wait for spring and possibly miss half the summer if you need to wait in line at a repair shop.
Then again, maybe it’ll all be working fine!
