It works
Replaced my old one with this one and had no issues. It does not come with screws so don't throw your old ones away. It works as it should.

Cracked cap.
The cap cracked and caused a miss 4 days out of returnable. A lot of money for one month of use.

OEM--fits nicely
Bought it to replace older corroded unit. Fit perfectly, but you'll have to use your older screws as the unit doesn't come with them.

OEM vs Sierra!
So, I needed TWO caps and rotors since I have twin motors in my boat.....but there was only ONE Quicksilver OEM set in stock...so I ordered it, and then ordered a Sierra kit as well....and thought I would compare, and see if there is a difference! (Next season as I am on the dry for the season now...)Well right out of the gate, the Quicksilver product seemed better quality! The cap was just about the same as the Sierra, but the ROTOR was definitely better quality!The Sierra had a SCREW that held on the contact point of the rotor, where the Quicksilver was riveted! Also the rotor BASE was more substantial than the Sierra! Heavier, better fit and finish, plus the rotor shaft was BOLTED (Via three small bolts) to the base where the Sierra was held in with three screws! (They didn't even look to be stainless!) I am sure both are "OK" but the BOLTED set up looked a lot more sturdy and better quality!Why four stars? The OEM kit I received did NOT include new cap mounting screws!!!!! Not a HUGE deal...but one of my screws was bent, and I needed to replace it!So, I have not had it on the water yet so I may change my idea either way if one does not perform, but just based on initial quality, and workmanship, I give a nod to the OEM over Sierra! The Sierra didn't look "Bad".....just not to the quality and fit and finish compared to the OEM.......
