What is the reduction ratio of the red gear on the RB-M 45?

The reduction ratio of the red gear on the RB-M 45 is 1.02:1. This ratio indicates that for every 1.02 revolutions of the input (the driving gear), there is 1 revolution of the output (the driven gear). This slight reduction suggests a focus on efficiency and torque management in the propulsion system. It allows the engine to operate effectively within an optimal power band while ensuring that the propulsion thrust is adequate for the vessel’s performance in various conditions. The selection of this particular ratio is essential for maintaining balance between speed and maneuverability, especially given the unique operational requirements of the Response Boat-Medium in maritime environments.
