Floridaj, We will try all we can to help you learn on this new trip into the fast lane. Where is the abrasion? Lower skeg, around an oil screw, exactly where? It might be sand from that trip at Okeechobee, and it can also be picked up when powering on the trailer, as this set up will pick up plenty more trash than your previous 40 pony did. You are very concerned with your purchase,and you want to keep in polished like a chromed out Harley. Some of that will subside, and the anal side of us all will keep some of it. You just ask us what you are needing to know and we will work our way through this together.BCB
