(Silicon Chip Magazine November ‘09) This easy to build module can dramatically reduce vibration & noise by ensuring the RPM of each engine is matched. Engine speed mismatches can also reduce efficiency and increase engine wear & tear. The kit reads the frequency signals from each engine tachometer and displays a readout on an analog guage. This shows RPM difference up to 200RPM on port or starboard engines.

Important Note For Kit Buyers:
This product is supplied in component form and requires soldering, drilling, and assembly. We recommend users are familiar with at least basic electronic principles and have the ability to solder.
