DIGITAL TACHOMETER

POLE NUMBER SET UP

The tachometer indicates the engine speed by receiving the pulses from the lighting coil.
The flywheel magnets used in Yamaha outboards vary in number of poles used: 6-pole and 12-pole.
It is necessary to change the calibration switch on the back of the meter to correspond to the partic-
ular motor being used.
Also, the selection of the engine type and the trim sensor type is required.
