I've been working on my ballast install today and I'm almost done but ran into a problem when tightening the thru hull nut. I had a buddy stick a prybar into the hole from the bottom to try and keep it from turning but you can't get any leverage. Anyways it's pulled flush with the hull and I used the marine sealant on the top and bottom, and there is no play in the fitting. Think I'm alright? Thanks
