Pumping versus discharge at sea (2 miles out) 350 Mariner

[medmonds]

Hi All,

I'd appreciate it if someone could help me out. I just purchased a 2002 Carver 350 Mariner. Is there a Y valve I need to turn to pump on at dock or discharge at sea? If someone would be nice enough to take pics and post or send them to me, I'd be forever indebted to you. When I turn on the waste circuit, I see no discharge coming out from either side of my boat. Please help!!!
