I started to look around the boat getting it ready for the season. I noticed that on the rubber tubes the connect the pipes off the riser to the y pipe theres alot of white crust and white streaks running down the y pipe. anyone else ever seen this?

Also I took everything apart and noticed theres no flappers Just the bar running across the top of the y pipe. Im the third owner of this boat so they may have been removed. If they have fallen down would there be any evidnce left behind?
 
Saltwater stains? Exhaust shutters can fall into the Y pipe and block water flow or pass straight thru. Flexible camera will help you see into the pipe.
