In general, what do you think about quality beetwin Merc VS aftermarket ?

EX :For a old mid '80 's 20 hp 2 cylinder Switchbox :

The OEM is 409,35 $ CDN
CDI is 269,99 $ CDN
Siera is 234,99 $ CDN

My choice is probably the CDI

For you, do you place CDI and Siera in the same level of quality ? Do you just use OEM ?

OEM as good as the Original Part, which of course failed.
As for the other two. I don't think there is much difference, probably made in the same Asian plant.
I always went OEM

OEM aussi bon que la pièce d'origine, ce qui a bien sûr échoué.
Quant aux deux autres. Je ne pense pas qu'il y ait beaucoup de différence, probablement faite dans la même plante asiatique.
Je suis toujours allé OEM

There are some switch boxes that are showing up on ebay and amazon, really cheap knock offs.
Some are around $50.

Don't use them.

Stick with cdi or sierra if not oem.

I put CDI on my old Mercury 3 years ago and the motor has run great

Serria 1st as best for quality/warranty....OEM 2nd and CDI last as their QC has fallen since outsourcing.
