Well, I ended up buying a Launch 21v in pretty mint condition and cant figure out the ballast system. It has 3 switches, one for each bag (fill & drain) but I cant hear the pump going when I turn them on. The previous owner said that it has some kind of gate valve or something so you need to be at cruising speed to fill the ballasts up. Anyone know if this is true? All of my other boats would fill up as long as you are in the water.
BTW it only has 1 pump and 3 electronic valves, one for each bag. So I would assume that the pump should turn on regardless of which switch I hit right?
