Upgrade Kits

You know your engine has years of service left — and we do too. Our Performance Upgrade Kits and Emissions Upgrade Kits include pre-selected parts, segmented for easy installation. All upgrades can be completed in hull, without any major vessel changes and can be done during an overhaul to help you stay on schedule and within budget.

Our Performance Upgrade Kit is comprised of the latest genuine Cat parts selected by our engineers for added savings, giving you the efficiency of a new engine from the one you already own. We designed it to be a benefit to your engine — and to your business. See a return on your investment before your first major overhaul.
