Isuzu UM6BG1TC – 226hp Marinised Propulsion Engine
Isuzu Japan Factory Marinised Propulsion Engine
The Isuzu UM6BG1TC is a high‑performance, marinised propulsion engine engineered to deliver dependable power for commercial vessels. Built on Isuzu’s proven 6‑cylinder diesel platform, this turbocharged and intercooled engine offers the perfect combination of durability, fuel efficiency, and smooth operation—making it ideal for operators who demand consistent performance in challenging marine environments.
Engineered for Commercial Demands
At the heart of the UM6BG1TC is a 6‑cylinder, vertical in‑line, 4‑cycle diesel engine with direct injection, designed for long service life and reduced fuel consumption. With a displacement of 6.494 litres, the engine delivers strong output across a wide RPM range.
- Rated Output (Medium Duty): 154 kW (210 PS) @ 2600 rpm
- Rated Output (Light Duty): 169 kW (230 PS) @ 2700 rpm
These options allow vessel builders and operators to match the engine’s powerband to specific commercial applications.
Turbocharged Efficiency
Equipped with a turbocharger and intercooler, the UM6BG1TC ensures optimal combustion and maximum torque under load. Its performance curves show a strong, steady rise in both torque and horsepower, supporting reliable propulsion even under demanding conditions.
Fuel consumption data across the propulsion curve underscores its efficiency, helping operators manage fuel costs without sacrificing power.
