How to choose and install a tachometer on a boat engine?

The bulk of motorized water crafts is equipped with a minimum number of systems to establish control over the engine operating modes. Receive important indicators relating to the engine speed, the total running time allows the tachometer for the outboard motor.

What is the device?

A tachometer for a boat engine is a small-sized device that is used to synchronize with the engines of swimming vehicles. Installation is made without direct intervention in the structure of complex mechanisms that are responsible for the course of the vessel.

The tachometer for the outboard motor fixes the impulses that come from the engine along the electric chain of the spark plugs. Based on the received data, the device displays the operating time of the engine and the number of revolutions performed.

A tachometer is produced for a boat engine made of waterproof materials. The weight of most devices is about 50-70 grams. The device operates from an autonomous power supply and starts when the engine is activated.

Functional

Today, tachometers are available in a wide variety of designs. The simplest devices are capable of displaying only information on the engine revolutions on the display. However, when choosing a truly functional tachometer for a boat engine, the owner of the boat will additionally receive data on the number of rolling hours, oil pressure, engine temperature. The presence of the last two possibilities looks desirable for low-power engines. However, the installation of additional sensors is often associated with serious design and technical difficulties.

Features of choice

Which is better to choose - a Chinese device or an expensive tachometer for Yamaha boat engine? The main argument in favor of devices from China is affordable for most users. According to this criterion, devices from reputable manufacturers, intended for installation on motors of eminent brands, will always lose Chinese products.

Another important point is the replacement of the battery. Here it is worth paying attention to the possibility of opening the lid of the device. In this case, it will be possible to restore the working capacity of the device on its own, without resorting to the services of specialists.

Among other criteria that need to be paid attention when choosing a tachometer for boat motors, it is worth noting the following:

• Clarity of the image on the display;
• The conformity of the device's capabilities with the characteristics of the engine's tact;
• Easy installation and operation.

Connecting the tachometer to the boat engine

The procedure for mounting the device involves performing fairly simple tasks, with the realization of which any owner of a water vehicle can potentially handle. The main thing is to perform the work in the following sequence:

1. To start, the device is removed from the original packaging, after which it is checked for damage.
2. With the boat engine removed the lid, which provides easy access to the spark plug. Around the last one, at a distance of about 5 cm from the tip, a free cable of the tachometer turns into several turns, which is fixed with the help of an insulating tape.
3. The device is fixed firmly on the dashboard of the floating craft with the help of self-tapping screws.
4. Finally, a high voltage cable is connected to the tachometer.

To install the device separately, you will need to purchase the appropriate wiring. The most difficult stage of installation is fixing the tachometer on the dashboard. On some motorized boats, the panel designed for this purpose does not open. In this case, the owner of the boat will have to resort to alternative solutions, showing ingenuity.

Finally

As you can see, the tachometer is a fairly practical equipment for owners of motor boats. The obvious benefit, the variety of assortment, the possibility of self-installation - all these are factors that persuade users to purchase such a device.
