FishPro Carbon Seal Old vs New - pitting and a bit over 1/4" of wear + dust after 75 hrs

After 75 hrs of riding in dirty (abrasive) salt water of the Texas Laguna Madre this is what the carbon seal and SS hat look like. This machine was cleaned after every ride, and the bilge and carbon seal and hat washed down. Yes, salt water will corrode stainless steel.
