I'm replacing the Y pipe assembly on my 1971 Trisonic,Mercruiser 888, Ford V8, 302, 188hp and need a diagragm/ part number for the O rings between the exhaust separator and the transom plate. Also, should I use a sealer in addition to the O rings?
cant help you with the part numbers. any dealer can get them. as for sealants use only perfect seal or 3m weatherstrip adhesive<br /> DO NOT use any sillycone<br /> good luck and keep posting
