Propeller Calc vs SpeedLink Competition

This calculator can determine pitch, gear ratio, RPM, propeller slip and speed parameters. Enter any four variables, and it will calculate the fifth. Use the toggle switch to choose which field to calculate. Pitch is the theoretical forward movement for one complete turn of the propeller. Every inch of the boat in contact with the water induces drag. Therefore, the distance travelled differs since the propeller is "slipping" behind the theoretical distance it should travel with each rotation. The difference between theory and reality is called slip. Depending on your application, slip typically ranges between 5% and 20%. A lower number is only sometimes what you are after. Slip of a prop changes with operating conditions and is not a direct measure of efficiency. Please consult professionals for guidance. Happy powerboating

SpeedLink provides owners of Mercury Racing’s next generation of competition engines (APX, 3.4L V6, & 4.6L V8) the ability to view live engine data and obtain detailed descriptions when a fault occurs. The full functionality of the app is only available when used in conjunction with the Bluetooth Low Energy SpeedLink module. When the app is open and connected to your module it requires a continuous connection and therefore may impact the battery life of your device. Features: • View live engine data : RPM, Battery Voltage, Engine Temperature, Engine Hours, Oil Temperature, Oil Pressure, Coolant Temperature, and more! • Receive active fault alerts and corresponding descriptive fault information • ECU validation tool for race officials to verify correct calibration is in the ECU (APX, 3.4L V6, & 4.6L V8) • Communicate wirelessly to your Mercury Racing competition engine through a Bluetooth Low Energy connection • Allows for normal phone operation – call, text, streaming music, search the web, etc. while connected to your Mercury Racing engine ************ IMPORTANT INFORMATION ************************* • Mercury Racing’s SpeedLink app is free to install. The SpeedLink module can be purchased through Mercury Racing. • The SpeedLink module only works with Mercury Racing marine engines. • The SpeedLink module simply connects to the engine controller diagnostic port located in the vessel.
