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.

OEM quality
I always buy factory parts-can’t go wrong 95% of the time-big issue with this product-bone heads at mercury think it’s funny to put bubble wrap around the rotor-place inside the cap so it will stick & jack up the gasket…-25 years and stillDoing it…

Factory replacement distributor cap.
I like the fact that it's an OEM replacement. I wouldn't say I like the fact that I either reuse or find 4-screws new.

v8 cap sent with v6 rotor
When I changed from my Siera cap and rotor, the thing that stood out was my new Quicksilver rotor having 6 slots vs 8 like the Serra. After full plugs and wires...boat ran like trash. Read reviews here and saw numerous people had the same issues months ago. This let me know Quicksilver shipping do not care about checking it's products when they know they have an issues.Now im sure I cant return it since its been installed....not to mention no bolts for the cap and the space is so tight that most bolts will not fit.I'll just buy from west marine in person like I use to.

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.......
