Well after a first year of a first time owner, I can tell you one don't that bit me. Don't put your trailer in too deep. Boat caught on the right side just before hitting the stop and shot off to the right missing the stop and getting the boat on the trailer sideways. Prop started hitting the frame of the trailer before I could get shutoff. Cost me about $260 for prop repair and some trailer paint from SC. Other than that we had an awesome year last year and am looking forward to the weather warming up.
