This summer I was given a 17’ slyvan super sportster on a shoreline trailer. The boat has been sitting on my patio while we worked on gutting it and fixing some issues. Today I decided it needed to be loaded undercover. Hooked it up got it backed it and now the back end is heavy and it raises the hitch off the ground. I am not sure why, anyone have any pieces of advice to figure out what’s going on.
