Even though you’re overhauling an old engine, there’s no reason you can’t benefit from modern technologies. Cat® Performance Upgrade Kits—available on select Marine 3500 engines—include a number of parts that can bring your engine’s performance in line with current standards.
The kit includes proven system parts to convert from a mechanical to electronic injection control system, for an average rated speed fuel savings of 4 percent. In some cases, fuel savings have totaled more than 9 percent.
Performance Upgrade Kits also improve load acceptance and acceleration while reducing vibration and noise. They improve diagnostic and display capability. And of course, they use genuine Cat parts for exceptional life.
