Re: OMC???
Big He,<br /><br />Yes, your '73' Johnson was manufactured by OMC. If you are referring to repair manuals, be careful. Some manuals that say 'OMC' may be referring to OMC stern drives (I/O's).<br /><br />By the way, other than paint, Johnson and Evinrude engines of the same year and horsepower were identical.
