This bracket breaks because of vibration. Putting a thicker bracket on is a
band-aid to the main problem. We need to fix the cause and not the result.
This vibration is usually from poor carb sync, gearbox vibration (maybe it needs to be shimmed), the prop (either blades out of pitch from each other or the prop is out of balance). It can also be bad or old rubber engine mounts or engine mount bolt torque too lose. These are the common causes. There are over 50+K engines out there with well over 5 million run hours and most don't have this issue. Best to find the cause because if it breaks this bracket it's working on other parts to. You may not feel a vibration as a human, but all engines vibrate. It you can feel it then it may be bad. Even if you think an engine feels smooth it just has a fine vibration that a human can't feel.
