Need your help guys, I have a 87 42' carver and want to refit the heads and system to something more modern quieter and less stinky. I currently have the standard 12v sea-water system that came with the boat and want to switch to something along the lines of the Sea Land Vacu-flush system. I am not too familiar with this topic and dont know where to start.Any pearls of wisdom or thoughts from the experienced folks as to the best system for this. Thanks in advance!
