I have a 2015 Sea Doo Wake Pro 215

There is a 1" diameter rubber grommet inside the right foot well. Does anyone know what it is for. Also, I saw on a diagram of the inside?! that shows a tube running to another connector, that appears to be 2-3 foot long. I believe it runs along the side to the front. I can stick a bic pen inside the grommet hole about an inch!
