Description

Rebuilt Engine for the Kawasaki Ultra 300X Jet Ski

The Kawasaki Ultra 300X Jet Ski Engine rebuild from REV6 covers the major areas of your 2011-2013 engine. We inspect your original core and rebuild it based on what we find. As a result, worn or damaged parts can be addressed before final assembly.

Our process covers the crankshaft, cylinders, pistons, cylinder head, valve train, bearings, seals, and timing components. Finally, another technician checks the completed engine before shipment.
