How To Register A Jet Ski Trailer In Florida

Registering A Gifted JetSki & Trailer in Florida

I was just given a used jetski and trailer from my brother. They both were previously registered in FL simply are at present iii years expired. I would like to re-register them both in my name, also in Florida. What paperwork/forms practice I need and what do I have to do to register it all in my name? I don't have a championship or "receipt of sale" because it was a gift. The only documents I have are the expired registrations for the jet ski and trailer... pls help I wanna become out there and ride it legally
