I have a 20 foot 1978 bayliner.It originaly had a volvo penta I/o but I guess the person that bought it two owners ago blew the engine and replaced it.Now I have a volvo penta 280 outdrive and an unknown engine inboard.The valve cover still has the original sticker saying waukesha motor company, pleasurecaraft marine engine division.Witch I recently found to be volvo mfg.So I got the serial off the block and begane searching .The serial # C4OE 9425-B on the block.The only thing I could find was this :1963 260 Cobra (CSX2000-CSX2075) would have a C3OE-615-C block casting code<br /><br />1963-1965 289 Cobra (CSX2076-CSX2589) would have either a C3OE-B or a C4OE-B block casting code<br /><br />Most of the 1964 289 Cobras came with a hipo 289 C4OE-1015-C block. Most early 289 Cobras came with a 260 block (C3OE-B C4OE-B) that started life out as a 260 block originally<br />(Most Cobra people don't know this).
