279Used STD cylinders from a sea doo 717/720. These cylinders are sold as cores. One has significant surface rust, and may have other wear. Other has some scoring. I am not seeing any cracks, but, they are cores and carry no guarantees. If you buy these plan to bore or re-sleeve based on your assessment/needs. What you see is what you will receive! I guarantee all our parts to be as described and pictured.
