I'm looking to replace the ignition coils on my 1977 85hp motor. What were the original OMC part numbers of these coils, and/or the aftermarket part numbers I should be looking for?<br /><br /><br />Thanks,<br /><br />Joe
581610 was the number,and it is now 502888,cost is $36.71.If you can save a bunch aftermarket,go ahead.If not purchase the real thing,and know it's right.<br /><br />DHP
