Yanmar Kanzaki KM4A 2.14:1 Ratio Marine Transmission
Yanmar Kanzaki KM4A removed from a Yanmar 4JH40 due to conversion.
The Kanzaki KM4A (often KM4A-2 or KM4A1) is a marine transmission commonly paired with Yanmar engines (such as the 4JH series), featuring a 7-degree down-angle output shaft. The 2.14:1 ratio refers to the reduction in speed from the engine to the propeller shaft for both forward and reverse, designed for high-torque applications.
