I have a 1989 Maxxum that so far this year has received a new couplar transome assembly outdrive and assorted other parts and peices. I now know I knew nothing about boats before buying this one and it has cost me haha. Since it is in peices I purchased the Eddie Marine Silent Choice bought a Y pipe. however the marine mechanic is telling me it is the wrong Y pipe because it doesnt measure right well I was told that is the part number I need, the catch is that the part number is not on the Y pipe only the casting number. can anyone tell me what the casting numbers for a Y pipe for a 1988 454 are. I know the part number is suppose to be 807130A4. The casting number on the one that I purchased is 861229-C.
