Everything worked great but they didn’t seem to drain as well as expected. One of the check valves didn’t seem to be working, when I put my hand over the thru hull it finally started to suck the rest of the water from the 720 through the rear bag and into the pump. I’ll have to make sure I didn’t install it backwards. Part of the issue could be an excessive amount of air in the system since it was the first time out.

I also realized the stock front bag has 2 vents/thru hulls so I need a second check valve up there.
If you have time could you take a pic of the bow side of the stock rear bag? I didn't look at our correctly when I asked you before and ordered the same set up you have but think now I may have to sell / return it and just order the update kit with the larger rears. Anyone want to do this upgrade with stock rears? I'll give you a deal lol
