2x Cummins QSB6.7M 300hp with Twin Disc MG5075A reverse gear

2x used Cummins QSB6.7M marine engines in excellent condition – professionally maintained.

This set consists of two Cummins QSB6.7M marine diesel engines (SN 73046779 and SN 73046830), which are demonstrably in good technical condition.

On 29/09/2025, an oil analysis was performed on both engines. The results show a generally very good engine condition: the concentrations of wear metals are low, and there are no signs of combustion issues, nor defects in the air filtration or cooling systems. This confirms that the engines are internally in good condition and functioning properly.

The analysis was conducted after an oil change and can easily be followed up during the next check-up for long-term monitoring.

The complete analysis reports are available upon request for inspection.
