The 581419 caps were used to compliment the original 580197 coils used in the motors shown. The more common 580321 cap is used with the more common 584477 coils which were used in just about everything else OMC built. Since the offshore coils are meant to replace the 584477 coils, go with the lower uF rated 580321 cap if you are replacing the coils. I know the coils look the same, but they are different.
So is there any real difference in the performance of the coils? Or differences in the way the stator plate and flywheel magnets are set up? I see these listed are higher performance motors. So would using these coils on my low-performance 5.5 be a factor in the marginal spark i’m getting?
How did this get so complicated?
