Been lurkin' awhile but haven't found my answer. Have my first boat (used)- '87 Bayliner, 21', 3.0L engine. I'd like to find a manual for the engine and outdrive, but I'm not sure what the engine is.<br />The outdrive is an OMC Cobra, but I cannot find any information on the engine as to the manufacturer. One sticker on the engine states OMC but all of the manuals I've seen so far for an '87 Bayliner state "for GM 3.0L".<br />Did OMC actually make a 3.0L back then, and if so, how can I distinguish between an OMC and GM?<br />Any information will be greatly (and I mean "greatly!!!") appreciated.<br />Matt
