Save on this new never used cylinder for the Polaris 750cc Jet Ski. OEM part number 3240210. This was on a dealers shelf when he closed his doors, it was in a bag and out of the box. Retails for over four hundred bucks, don’t waste your time with a used one. This has some very slight dirt or oxidation, it will clean right up with a little bit of scotch brite or a quick pass with a dingleberry hone.
