Just the vent hose for the crankcases. As long as its air - its normal

During normal running the breather should blow but it will suck while starting. If you are going to be doing a lot of deep water riding, then route the pipe up & into the airbox. You can add a filter or catch tank to the end, to stop your airbox/filter gettin' messed up.
