Rating based on 2018 Mercury 4-Stroke 6 HP If you force it you will most likely tear/cut threads on your engine. I had to drill holes in this fuel pump to make it a bit wider so the bolts lined up properly. The item works fine after installation. If you're a backyard mechanic with experience making small modifications and don't mind the risk of property damage/voiding the warranty, then it might be worth it. If you're buying a product and expecting it to just click and work, then I wouldn't recommend it.
