Merc Racing 525EFI. SAE or Metric fasteners?
 

Thanks in advance!

both

+1, just did a little work on a friends last weekend and you need both

Thanks guys!

Yes (sadly, most modern engines seem to use a mix)

Thanks jimmy Carter, moron..

9/16 = 14 mm fyi. Arctic cat is famous for that

fixed it for ya. But a 14mm wrench works good to remove a bolt with a 9/16 head

Going back to sleds. Ya what the hell dose cat engineers think mixing SAE and metric fasteners on the same sled :angry-smiley-038:

But that is why I ride a Doo...... :).

I'm all for metric on everything! When I renovated my house I used a metric tape mesure....so much easier than doing the math with fractions

most of the world uses the metric system,we were actuially way behind the rest of the world when we started with the metric threads&fasteners.imo it is narrow minded to blame jimmy carter or anyone else for attempting to conform to the rest of the world.
