Two identical medium speed engines are connected through clutches and a reduction gearbox to a single controllable pitch propeller. It is noted during normal operation that the load sharing between the engines is uneven with one engine taking a greater proportion of the load as the total load increases even though they are equally loaded at low load.

What is the most likely cause of this problem?

Answer:

The governor droop settings are incorrectly set and are not matched.

When engines connected mechanically (via gearbox) or electrically (via common grid, in case of generators), their governor droop settings must be set to same value, because droop determines how the engine reacts to load changes.
