Picked up a screw in my left rear tire. When I got home I jacked it up and hit it with a 1/2 drive impact. First 2 came off easy. 3rd one I had to use a breaker bar. The last two took 3 hours to get off. Broke 2 sockets and a breaker bar with a cheater pipe on it. Went around to the other 3 wheels and checked to see if I could break them loose. All good there. But it would have been a bad deal if I had been on the side of the road. Boat was new in May 2020. 1st time I've tried to break them loose.
