Every spring when George and I pick the boat up at New England FreshWater Marine, Bill Marsh (owner/sales man/mechanic extraordinaire) says,"Boys... Don't forget your drain plug, don't forget your drain plug, don't forget your drain plug." Thanks to Bill we haven't forgotten the drain plug. Unfortunately, this fellow Mastercraft owner obviously didn't buy or store his boat at NEFWM.
Here is an example of what happens when you forget to put the drain plug in your boat.
