Used Boat Purchase Paperwork?

Going to pull the trigger on a 2008 Beavertail. Y’alls input on what to look for has REALLY been great help. Need one last set of questions, What paperwork and filings need to be done on boat purchase? Title to boat and trailer, TX #’s and boat reg tag (is current, will that transfer)?, motor? What gets filed with taxing authorities, city, county, state? Insurance, USAA is my carrier, what about Tow Insurance? Need Make, Model, year, BHP anything else?



Any input I have missed is GREATLY appreciated!!!
