Engine Rebuilds At Newcastle Jet Ski Centre we can look after the maintenance and rebuild of any 2-stroke or 4-stroke PWC engine. Some of the services we provide include the repair of chrome and Nikasil cylinders, head servicing/reconditioning, Seadoo supercharger hourly rebuilds, and crank remanufacture. At Newcastle Jet Ski Centre we believe an engine rebuild should be performed up to a standard, not down to a price so every repair or rebuild is performed using only quality OEM (original equipment manufacturer) standard components, not cheap junk! Of course each rebuild is tested and tuned using our water testing regime and as a lot of engine damage is the result of an equipment failure elsewhere, all your PWC’s ancillary items – such as fuel, oil and cooling systems – are checked for peak performance. We look for the cause of the problem, not just fix the problem!
