See full version: Sierra vs OEM Mercury
I have purchased many sierra impeller kits and other parts without any issues. I did buy an unknown brand bellhousing gasket kit. I will NEVER buy anything other than Mercury bellhousing gaskets. I think you will be fine with the Sierra. more
I have bought some after market parts (Sierra, GLM, etc) with great success and others not so much. In order to find out on any specific part, I usually google for any forums comments, reviews, etc about the specific item & brand. Doing that I steered clear of Sierra & GLM brand manifolds and risers. I have bought a GLM trim cylinder at 1/2 the cost of the Mercruiser and it was fine.
Having used both on customers boats, I would choose OEM hands down for mine.
I had a situation where my Sierra impeller was smaller than the OEM. The OEM burned up in the smaller Sierra housing.

Aftermarket Parts Cons: here
An aftermarket part is any part that is not sourced from the engine manufacturer. Notice I did not say “made by the engine manufacturer”, because in many cases the OEMs are sourcing parts from other vendors in the same way the aftermarket companies do. All the major aftermarket manufacturers supply parts designed to function as well or better than the original, they will “meet or exceed” the design specifications of the original part. If the aftermarket part is a direct replacement of the original part it will not void your engine warranty.
Cost: The OEM parts are almost always more expensive although some of the engine manufacturers and feeling the pinch and are trying to offer matching pricing on the fast moving parts that are available as aftermarket.
Cost: The aftermarket parts are usually less expensive than OEM. The amount you save will vary by part and by brand, but you can often save 20 – 40% as compared to OEM.
Warranty: Contrary to what most consumers think the aftermarket manufacturers generally have a better warranty on their parts than the OEM does. They need to offer a better warranty in order to overcome the consumer concern about buying aftermarket. more
