• You are buying a complete Yamaha 1100 triple engine out of this jet ski. You will get the carbs, starter, stator, long block, pto coupler and mounting brackets. The compression is 116psi in all cylinders. It will be drop in ready with you adding your exhaust. This is a local pick up and will be pulled out when the full payment is made. I'm parting this ski out so if you need more parts let me know.
