If you think you know the Cat® C4.4 ACERT marine generator set, think again. The latest model is all new — and the updates combine to deliver better performance, lower costs and easier operation aboard your vessel.

New fuel system for clean, reliable operation

The C4.4 ACERT now features a common rail fuel system that generates all the power you need for onboard operations with less fuel burned and fewer emissions generated. This electronic engine is extremely reliable, exceptionally quiet and virtually smoke-free.

New cooling system for simpler installation

The days of needing two keel coolers are over. With its single-circuit cooling system, the new C4.4 ACERT allows for plug-and-play installation on new or existing vessels. Repowering? Use your current keel cooler to save time and money.

New maintenance routine for less downtime

If your dream generator is one that requires little more than an oil change every 500 hours, you'll love the C4.4 ACERT. Maintenance is extremely simple, thanks to features like:

  • Self-priming fuel system — no need to bleed the system
  • Anode-free operation — no zinc anodes required
  • Gear-driven water pumps — no overheating due to a failed belt
  • Hydraulic valve lash adjusters — no time-consuming manual adjustments

Quick delivery for quick repowers

When you're ready to repower, you don't want to wait. Now you don't have to. Thanks to our new U.S.-based inventory stock, you can get the new C4.4 ACERT marine gen set or the previous C4.4 model faster than ever — and get back out on the water.

Here's something that's not new: the backing that comes with every Cat engine. Wherever you are on the water, there's a Cat dealer nearby with the parts and service you need. And when you combine the C4.4 ACERT with a Cat marine propulsion engine, you only need to make one phone call for all the support you need. That's another big time- and money-saver.

Get all the details on the all-new C4.4 ACERT marine generator set, then talk to your local Cat dealer about special offers available now.
