Boating Performance - Killcare

Torque is directly proportional to the horsepower passing through and inversely proportional to the shaft speed (RPM). In Figure 8-1, the engine delivers torque through its crankshaft to the drive shaft and finally to the propeller shaft. The transfer of torque, or twisting force, from the drive shaft to the propeller shaft is made through gears.
