Took me about 4 hours for it all, but if I did it again, I could do it in much less. You've got 1" vents already don't you? One of my hardest parts was pulling out my 3/4" vent line and replacing it with 1" for my center bag. Your boat is different, but it also helped to remove the kick panel under the helm - 1 screw under each cup holder (2) and 3 for my panel. It is just as hot now as when I did mineFor the existing lines that I added things to, like the bosworth, I took a small pot of hot water out to the boat with me so I could easily do the fittings. Install the IBS first, it takes the most time.
