ANALOG TACHOMETER
A tachometer is essential for suitable outboard performance.
The engine speed can be monitored for most efficient operation.
In twin motors applications, the tachometers can be used to set the throttle of each engine accu-
rately.
ANALOG TACHOMETER APPLICATIONS
* Tachometer with triple oil indicators (Ref. No.2) requires the relay to light the indicators.
See the wiring-diagram to connect the relay (P/N: 6Y5-81950-02).
* If the current tachometer does not fit the older engine, use the wire-harness adapter which is shown in page
5-43.
