The Harmony Drain Plug Kit is easily installed and much appreciated when the need arises. The Drain plug Kit allows for easy removal of water trapped in your boat. Kit consists of captured drain plug, threaded fitting secured by screws and well nuts.
This kit is relatively simple to install, just make sure you follow the instructions. You will need to have silicon caulk (not included) and a drill with drill bits. It will take you about 10 minutes to install and is ready to go the next day. I have taken my boat out a few times since installing it and no issues with leaking. My boat didn't have a drain kit already, so I can't say how this would work if you were trying to replace a broken drain plug.
