I was just wondering if any of you have installed a ballast system with bags. What type of setup did you do and what was involved in pluming the bags in. I have a Mastercraft x-30 and would like to put bags on both sides of the motor in the back and one under that seat just wondering what type of pump to get and what is the best way to plumb the system in? And where is the best place to tap into lake water in teh boat should i just drill a hole or tap into the fresh water hole for the motor. Again thanks for any input.
