I brought my boat home to clean, and i wanted to make sure the paddle wheel was in good shape cause my perfect pass hasnt quite been holding speed like it should. It looked clean of debris and spun freely, but i couldnt help but notice this:

it starts from a little more than half way on the bottom (say from where the cooler is to like the ski pylon) and its deep enough to put my fingernail in, like a heavy keying of a car. Is this normal wear and tear, or does this need to be addressed quickly because it will get alot worse?

Where It Starts:


End: A tic tac size spot where i can see the fiberglass chipped away.
