I have a 1990 Citation boat with an OMC Cobra stern drive powered by a Chevy 4.3L/2 barrel/V6 engine. I am trying to find the original OMC manual for my stern drive. There seems to be plenty of OMC manuals from 1986, 87 and 89, but I haven't even scene one from 1990. Can these year's manauls (i.e., 87, 89) suffice for my 1990 I/O? BTW, I bought the Seloc manual but wasn't too pleased. <br /><br />Also, I noticed that the manuals appear to have part numbers. Does anyone know the part number associated with my drive/engine? <br /><br />This is my first ever post on a message board, so if I screwed up on something, let me know. <br /><br />Thanks
