Reduce Fuel and CO2
Even though you’re overhauling an old engine, there’s no reason you can’t benefit from modern technologies. Cat® Performance Upgrades—available on select Marine 3500 and 3600 engines—include parts that can bring your engine’s performance in line with current standards.
The upgrade includes proven system parts to convert from a mechanical to an electronic injection control system for a significant fuel reduction.
Performance Upgrades also improve load acceptance and acceleration while reducing vibration and noise. They use genuine Cat parts to improve diagnostics and displays for an exceptional lifespan.
Our high-performing quality marine engines and power solutions receive product support backed by our global dealer network. No matter where your vessels operate, you can count on our dealers' expertise to keep your machine running productively and profitably. Find what you need to ensure your ship operates at peak performance.
