Tachometer on motor boat – a small device that is used to synchronize motors with swimming vehicles. The Assembly is made without direct intervention in the structure of the complex mechanisms that are responsible for the vessel.

Tachometer for outboard motor detects the pulses that come from the engine via the electric circuit of the spark plugs. Based on these data, the device generates the display of the engine and number of revolutions.

Made tachometer for the outboard motor from waterproof materials. The weight of most devices is about 50-70 grams. The device operates from an independent power supply and is started at activation of the engine.

Functions

Today widely available are tachometers in various versions. The simplest devices capable of producing on the display only information relating to the revs of the engine. However, choosing truly functional tachometer for the outboard motor, the owner boats additionally receives data on the number rolled, engine hours, oil pressure, engine temperature. The presence of the two latter possibilities seems desirable for low-power motors. However, the installation of additional sensors is often connected with serious structural and technical difficulties.

3. The Device is firmly fixed on the dashboard of a watercraft by means of screws.
4. In conclusion, the tachometer is fed a high voltage cable.

To install the device separately you will need to purchase the relevant transaction. The most difficult stage of installation-fixing the tachometer on the dashboard.
