Suzuki 6hp 4 stroke vibrating

[brodie123]

I have a Suzuki 6hp 4 stroke - approx 3 years old. It seems to be vibrating more than usual.

First thing I checked was the prop by not even a scratch. The vibration seems to be coming from the top end. The gas I am using is 87 Octane - about 4 months old.

I'm not sure if it's out of warranty - I will for sure check. But thought I might get some ideas of what to check here first.

Any thoughts?

4 month old gas is probably your problem.
