I am new to Mercury's, so have a quick question. I just bought a 2001 pontoon with a 90hp Mercury on it and have found a vent tube that has a plastic 90 degree elbow broken off just above the lower unit. The question is what is the vent tube for and where should the hose terminate to as it seems to be cut only about 12 inches above the elbow? Does it terminate inside the cowl? Is there any thing I should check in the lower unit once the elbow and tube is replaced? Thanks for any help.
