Does anybody have experience or recommendations for sierra parts. I am asking about the yoke assembly part #18-6401 for a Bravo 3 serial #om111208. Thanks
 
Never that particular part, but I have used lots of Sierra parts - water pump, water pump impellers, ignition components, drive belows) - I personally have never had a problem and cannot really tell the Sierra from OEM, at least not in terms of fit and function. Never felt a Sierra part was substandard to OEM. For me they work well, are a little cheaper and easy to get. Never had to, but since I do most of my own work, replacing a defective part is just my labor.

Now, on something like this, I might be inclined to go OEM unless there was a huge cost difference and or I could find someone with direct experience with that part. You have to consider the labor to replace a defective aftermarket part if there is a problem. Of course there could be a problem with the OEM part also.
 
Sierra is owned by Dometic, some people have had good, some people have had bad experiences with them.
 
I have used a lot of Sierra parts for things like water pumps and manifolds. For high torque, internal parts that can really cause some excessive wear if out of balance or, worse, break, I go with OEM. In fact, I just replaced both of my drive yoke assemblies with OEM.
 
I had a set of sierra heads installed on my 5.0 mpi. After bending the same exhaust valve on two different occasions, we replaced the faulty head with a OEM . Problem solved. Later found that the water jacket around the valve guide was partially cast in the head causing a hot spot, causing valve to stick. (not a quick or inexpensive boat experience)
 
My only question is who makes OEM parts verses aftermarket parts someone has to be making both of them. A bad part can be spit out by any manufacturer on any given day one matter who's label is on it.
