However according to the owners manual there are 2 freshwater tanks.
Will keep reading up on it but if anyone has this boat and can shed some light it would be greatly appreciated.
It is possible the boat has two tanks and your indicator 1 encompasses both. Many of our boats (ours is a 2002 model of an affiliated brand with Mainship) were built with two tanks, one on each side. Typically, the fill goes into one tank, there's a crossover hose connected to the other tank (and they level each other out), and the freshwater pump draws from that second tank. I happens our fill leads to the port tank, and our freshwater pump draws from the starboard tank. We have only one gauge for freshwater, and it only shows total status, not the status of each separate tank.
You can maybe check to see if that applies but eyeballing your tanks, finding a crossover hose if one exists, locating the freshwater pump, etc.
That could well mean your indicator 2 is for the black water tank, especially since you've determined your black water tank is actually full. If you have that pumped out, then recheck indicator 2, you may see a correlation there.
