I haver a "CD" sevice manual (P/N 507547 for my 1986 Johnson 150 (model #J150TXCDC), but I can't find the correct hose routing guide in it. I am specifically in need of the recirculation hose routing guide. Between each carb there are three recirc nipples/barbs and two additional nipples/barbs below the lower carb for a total of 8. Can someone help me out with the correct hose routing?
