HOLT CAT® offers Cat® Engine Upgrade Kits for select marine 3500 engines, providing significant benefits for your next overhaul. Two categories of solutions are offered, including Cat Emissions Upgrade Kits and Cat Performance Upgrade Kits.
Cat Emissions Upgrade Kits (E-Kits) - These designs are focused on regulatory compliance and/or sustainability efforts and often carry compliance recognition through certification or verification. These kits also provide many operational benefits such as improved diagnostic capability, lower vibration and noise, and often lower fuel consumption.
Cat Performance Upgrade Kits (P-Kits) - These designs are focused on fuel savings and often result in a quick return on investment and on-going savings. These kits also provide significant emissions benefits but typically will not carry a compliance designation.
