If your boat has excessive water in the bilge and seems like its always pumping and you can’t seem to find the leak check this out. I found leak to be around the drive shaft packing nut. It’s only $14 worth of no leaking packing to fix this. It does require two large wrenches or adjustable wrenches 1 7/8’ inch so I did buy one for $30, but for $44 I fixed a leak that has been bothering me for years. I bought the parts from www.skidim.com and attached a video they did as well.
Mine was so bad the leaks your see in the photos was with it just sitting in the water without the engine running. After this 20 minute job it doesn’t leak a drop.
Hope this helps you
