One of the most common questions we are asked is, what's the difference between Quicksilver and Mercury? In a nutshell, nothing.
QUICKSILVER HISTORY
According to Mercury Marine, no aftermarket company comes close to the level of research and design as Quicksilver products. And no other company tests their products like Quicksilver, either. Literally, millions of hours have been spent on fired-engine testing and analysis. Quality and integrity are paramount. Buying Quicksilver is buying performance, protection, and peace of mind.

So, it comes down to a matter of personal preference, availability and price for the consumer. We carry both products on our site at discounted prices. Be aware though that Mercury Marine sells many of their parts in Quicksilver packaging so as a dealer, we have no choice on how it's packaged. If you'll look closely at the bottom of every package it usually says: "Products of Mercury Marine™, Fond du Lac, WI 54936-1939". For example, this key
has one part number only and can only be ordered with this part number which comes in "Quicksilver" packaging. It's a Mercury key with a Mercury part number, totally OEM. You can't order it any other way. There is no other version/packaging.
Yes we know, totally confusing.
