I need to replace the transom shower hose on my Hunter 45CC. The hose is broke off behind the box where it connects to the water source. The only access from the back, in the locker, is a small covering that is not close to the box. I can barely touch the area, but certainly cannot reach it to work on it. I am thinking I will have to take off the box to work on it, but am hesitant. Don't know if I need to take the hot and cold knobs to take out the box. Any suggestions would be appreciated!
