⭐⭐⭐⭐⭐ Captain James Holloway - Offshore Tugboat Fleet
"We upgraded three of our harbor tugs with the Cummins Kta38 Marine M2 (Advanced Model) last May. After 7 months of continuous operation, including heavy docking maneuvers and storm-response towing, the engines have been rock-solid. The 4000 Nm torque handles barge pushes effortlessly, and fuel efficiency is noticeably better than our old units—about 10% savings per voyage. Maintenance is a breeze thanks to the modular design; we replaced a fuel injector in under two hours with minimal downtime."Purchase Date: May 2024 | Usage Period: 7 months
⭐⭐⭐⭐⭐ Elena Rodriguez - Private Yacht Owner
"I installed the Pro Model of the Cummins Kta38 on my 72-foot luxury cruiser for a transatlantic trip. I was skeptical about a commercial-grade engine in a leisure vessel, but wow—smooth, quiet, and incredibly reliable. Even in rough North Atlantic swells, it held steady at 1,800 RPM without a hiccup. The IMO Tier III compliance was essential for docking in environmentally regulated European ports. And the red finish? Turns heads in every marina."Purchase Date: February 2025 | Usage Period: 4 months
⭐⭐⭐⭐☆ Mike Dawson - Alaskan Fishing Fleet
"Running the Base Model on my 65-foot longliner out of Kodiak. Harsh conditions, salt spray, constant vibration—this engine doesn’t flinch. We’ve had it for 10 months now, and aside from scheduled oil changes, zero issues. The steel construction is holding up great against corrosion, which is saying something up here. Only reason I’m not giving 5 stars is the 6-month warranty—I’d feel better with 12, especially for remote operations. Otherwise, solid workhorse."Purchase Date: October 2024 | Usage Period: 10 months
⭐⭐⭐⭐⭐ Dr. Arjun Patel - Marine Propulsion Consultant
"I’ve specified over 200 marine engines in the past decade, and the Cummins Kta38 M2 stands out for its engineering maturity. Recently integrated the Advanced Model into a new offshore crew transfer vessel. The modular architecture allowed us to customize the exhaust and cooling systems for North Sea conditions without delays. Fuel efficiency tests showed 18% improvement over comparable 16L diesels, and noise levels at 80 dBA make it suitable even for crew comfort-sensitive designs."Purchase Date: August 2024 | Usage Period: 8 months
⭐⭐⭐⭐⭐ Lena Fischer - Offshore Platform Support Operator
"We use the Pro Model to power auxiliary systems on a semi-submersible rig in the Gulf. Extreme conditions, high humidity, and constant exposure to seawater—this engine thrives. What sold me was the triple corrosion resistance and cold-start reliability. Even after a 48-hour shutdown in humid conditions, it fires up instantly. The 24/7 Cummins support helped us troubleshoot a sensor issue remotely in under 30 minutes. That kind of service is priceless offshore."Purchase Date: January 2025 | Usage Period: 5 months
Average Rating: 4.8/5 ⭐ (94 Reviews)
Captain David Monroe - Marine Engineering Specialist
"For vessels requiring high torque, durability, and regulatory compliance, the Cummins Kta38 M2 is a benchmark in modern marine diesel design. Its modular system and ISO/IMO certifications make it ideal for both retrofitting and new builds. I particularly recommend the Advanced and Pro models for operators in emission-controlled zones."
Tina Wu - Maritime Fleet Operations Director
"After evaluating multiple diesel engines for our cargo fleet, we chose the Cummins Kta38 Advanced Model for its 20,000-hour MTBF rating and fuel efficiency gains. The 12-month warranty on the Advanced tier gives us peace of mind, and the global Cummins service network ensures we’re never stranded during port calls."
