After planning a weekend of fiberglass work I went to pick up the boat and smacked the coupling with the ball hard enough to warrant it's replacement, that and it was 20 yrs old and tired....So once the kids were in bed a friend and I headed over to my woodshop tonight to replace it. I bought a 2" ball 3500lb replacement coupling and grade 5 plated bolts planning on having it welded on, but the boat has to move by monday am, so for now I'm sure the bolts will do, if you disagree please let me know, any advice here would be great. Here are a few shots of the project< Next time I'm wearing pants......
