What technical characteristics of outboard motors should the buyer analyze first? Below we will look at the most important ones. And now I would like to note that many people make the mistake of focusing solely on the cost of the unit.
This parameter is certainly important, but it does not always make it possible to choose a motor that will cope with the scope of work planned for it. Any power unit is an extremely delicate mechanism. Therefore, when intending to purchase it, it would be a good idea to understand technical indicators characterizing his work. Which ones exactly, let's figure it out.
The Overseers, who power their energy from electricity instead of fossil fuels, are of course his because their image was lousy. The current had to be stored in large batteries on board, the charging time of the batteries was eternal and the service life was minimal. On the other hand, a gasoline-powered outboard can be refueled easily and almost anywhere, giving you an almost unlimited range. And comparing both types of drives objectively is really difficult, and quickly one is again in preconceptions about the advantages and disadvantages.
The most important points in choosing a PLM
Here we will talk about the main technical characteristics of outboard motors, and also explain what they affect.
Number of PLM cycles. The buyer has only two options - a two-stroke or a four-stroke engine. Say that the first at times better than second or vice versa is not possible. "Twos" have their advantages and weak spots, and the “fours” have their own. Let's just say: it's more suitable for the average user two stroke engine, because it is easier to manage and operate.
Who will be the king of the dwarves? Admittedly the smallest, standard manufactured outboard motor in the large motor stage aquatic species sport does not play a supporting role; Therefore, classifying it into the "toy" category is nevertheless a serious misunderstanding for many. On the one hand, they are built with great technical effort and are the ideal drive for a small boat that hangs in the Davids or is rolled up in the storage area below deck in the proven short version.
On the other hand, anyone who wants to have fun with them does not have to have a driver's license, but in any case he is mentally and physically fit to drive a boat and must be at least sixteen years old in domestic waterways. In the case of sea routes, suitability is limited by age.
Power. What is important is its minimum and maximum value. In the first case, the power should be sufficient to achieve planing (movement almost above the surface of the water against the current). In the second, the value must be less than or equal to what is indicated on the transom tag. If you exceed the recommended value, you can not only lose control of the boat, but also the boat itself.
Which outboard motor to choose from the Chinese ones
This means that even if the handling of compact motorcycles is child-friendly, “our dear little ones” are not allowed to ride for long periods of time. At least not always and everywhere. Too bad, everyone knows that handling small engines and corresponding boat children makes a heat pipe and is ideal training for future leisure captains. In the adult world, popular ministers have established themselves as hands-on helpers with the boat and slider.
Selva did not respond to our invitation to take the test. A prerequisite for successful operation in this performance class is light weight, small size packaging, ease of handling and attractive price. In addition to the fact that there are no serious transport problems, as with all other test engines, a fairly large, well-rounded handle is required.
Fuel consumption. What is important here is what type of PLM was chosen when purchasing - 2-stroke or 4-stroke. Practice shows that the second one is more profitable. As you know, during the operation of the “two” you need to prepare the fuel mixture yourself (gasoline + oil). There is no need to do this with “fours”, since fuel and oil are poured into separate containers. We would like to draw your attention to the following fact: the maximum flow rate indicated in the passport may vary depending on the boat on which the engine is installed. Simply put, in each specific case the consumption will be different. If your goal is to cover long distances, go for a four-stroke engine. However, be prepared to pay a lot of money for it. It will be possible to justify your expenses in five years (at best), so think carefully.
In the case of petrol engines, which in all cases are used as single cylinders with overhead camshaft and two-valve technology, the ventilation of the built-in reservoir and the petrol tap must be closed and the engine must be installed on the marked side. On the folding tiller, which reduces the size of the package, you cannot do without a small one of the manufacturers.
When working with the motto "attach, tighten, move down". However, you should not forget to use the quick start before starting and open the tank vent and petrol tap. Those who choose an electric motor may forget the "put on" and "tank" themes.
Noise level produced. Speaking about this parameter, we involuntarily return to the comparison of two- and four-cycle PLMs. Without going into details with the number of decibels at the “excellent” and “almost good” levels, we note: the “four” is more suitable for driving at medium and low speeds, because it is quieter than the “two” and creates, let’s say, the right noise. This means that the four-stroke engine produces low noise. The human ear tolerates it better than the sonorous sound more typical of two-stroke engines.
The critical point is that the engines can be started with a gear coupled. This is not only the speed, but also the direction of movement, which is determined by simply turning the throttle handle. If you want to change gasoline engines, the engine must be rotated 180 degrees. It sounds a little difficult, but with some exercises it really isn't a problem.
The same applies to adjusting the smooth operation of the pins and throttle knobs. The ease ends with the adjustment of the trim position, which can be easily changed only in the water with the help of Mercury and Tohatsu. The entire test report with all results and consumption values can be found already available on the kiosk!
Control system. Can be remote or tiller driven. The first one is more convenient (and, by the way, safe). But it is advisable to install a remote control on a ship only if its [ship’s] length exceeds 3,500 millimeters. For a fishing boat, a tiller is more suitable.
Starting system. It can be electronic or manual. Electronic - more modern. It makes it possible to start the PLM with a slight movement of the key. There are varieties that can control the heating process automatically. In addition, the advantage electronic system is its ability to support remote control by ship. In the case of a manual one, you will have to be content exclusively with the tiller.
Exclusive engine concepts in the field of four-stroke and two-stroke outboards with electronic direct injection have made Mercury one of the leading manufacturers of outboard engines. Advanced technology, the most sophisticated components, intelligent features and unrivaled fuel efficiency combined with a leading safety guarantee give you the safety you expect from your engine for years to come.
Smooth, quiet performance, low emissions, low fuel consumption and good looking modern design- these are the main features of these engines. Taking pleasure is a big advantage small boats and especially. There are many different electric motors on the market today. But which one is right for your purposes? Here we explain what is important.
Hanging boat motors 9.9 hp can already be separated into a separate class, since their “power - weight” ratio, the features of the current Russian legislation and some design nuances make them a unique offer for domestic powerboaters. Let's start, perhaps, with the peculiarities of the current legislation of the Russian Federation, according to which a certificate for the right to operate a small boat is required if the engine power exceeds 5 hp. However, there is one more point that states that a certificate for the right to operate a small boat is necessary if the vessel is subject to registration with the State Inspectorate for Medical Information. According to the current GOST R ISO 8666-2012, registration is subject to small vessels, the weight of which with the MAXIMUM engine power recommended by the manufacturer exceeds 200 kg. and also if the engine power exceeds 8 kilowatts (10.88 hp. Author's note). Thus, the majority inflatable boats with a length from 320 to 380 cm do not fall under the requirements for mandatory registration and, if used with an engine with a power of up to 8 kilowatts (and this is exactly the PLM 9.9 hp), then they do not register or receive a certificate for the right to operate a small boat no need. The second important point is the weight-power ratio. PLM power 9.9 hp
Electric motor as an environmental protection factor
They are now an integral part of the boating business. Boat electric motors are easy to operate and have large area applications. In waters where the use of internal combustion engines is prohibited for environmental reasons, electric outboards are the only way to navigate the water. As a boater, you could often be lost without an electric outboard motor. For example, the weather changes quickly, it is almost impossible to reach the shore of salvation on big waters, alone with muscle strength.
In practice, this is expressed in the fact that the weight of modern PLMs with a power of 9.9 hp. depending on the manufacturer and model, it ranges from 33 to 41 kg. and this means that such a motor is quite capable of being lifted, moved and installed on the transom of an inflatable motor boat one person of average build. Well, the last point concerns the design of these engines. The fact is that most of them are made unified with a 15 hp PLM. and knowing about this feature, many owners resort to a little trick, increasing their power to maximum through a small modernization.
Electric motor vehicle and enhances your own safety. However, it is important to note that large currents cannot be handled electrically outboard motor, since motor fishing vessels have electric motors with lowest power and traction.
Due to its low weight, the electric motor can be used with almost all types of boats. Up to a power of 3.68 kilowatts, no driver's license is required. Additionally, although the electric motor is not completely silent, the shear effect against the loud rattling internal combustion engine is greatly reduced. Even in shallow waters, the angler enjoys the quiet electric motor and can greatly control the speed of the boat. Last but not least, the operating, purchasing and Maintenance electric motors are very low compared to internal combustion engines.

The logo of this manufacturer bears the “three tuning forks” sign, since initially the Japanese company Yamaha specialized in the production of... pianos. By the way, one of the divisions of this concern still produces musical instruments. During World War II, production was repurposed for military needs and this event can be considered the beginning of Yamaha's engine-building activities. Today, Yamaha outboard motors are very well known to Russian boaters, and the Yamaha 9.9 motor was one of the most popular engines until recently. Why until recently? Because due to the fall in the ruble exchange rate, this engine has become the most expensive in its segment and today (October 2015) costs 121,200 rubles. Specifications This engine, compared to others, can be called average: dry weight 36 kg. Engine capacity 246 cm3. Speed 4500-5500 rpm. min. This engine can also be upgraded and increase the base power to 15 hp. -
Distinctive feature This engine has a patented control system. All actions related to changing forward and reverse gears, gaining speed and the “stop” button are concentrated on the tiller. This very convenient control system made this Mercury motor popular not only among ordinary boaters, but also in a sports environment. From performance characteristics This engine can be noted for its highest dynamics (speed range 5000-6000 rpm) and a good combustion chamber volume of 262 cm3. but you have to pay more for convenience and dynamics high flow rate fuel compared to analogues. Thanks to the ratio of high speeds and engine volume, the two-stroke Mercury 9.9 is able to work steadily for a long time at low speed, which is important when fishing on the track. Also, for a very long time, the Mercury 9.9 M PLM and its twin brother Mercury 15 M remained the lightest in their class (dry weight 35 kg). The cost of the Mercury 9.9 M today is 92,200 rubles, but it’s easy to buy it in general It is only possible to order, since the 15-horsepower version of this engine is mainly imported to Russia, which does not cost much more (95,500 rubles). - Suzuki DT 9.9 AS
Serial production of this engine began only in 2013, so there are very few usage statistics on it as such. In pursuit of weight reduction compared to the old Suzuki model, the flywheel was lightened, the crankshaft diameter was reduced, and some body parts, such as the engine pan, were replaced from metal to plastic. As a result, the weight of the motor decreased from 38 kg. up to 33 kg. while maintaining the largest combustion chamber volume of 284 cm3. among classmates. Only time will tell how effective these manipulations turned out to be, but users note increased vibration of this engine at medium and low speeds, which causes some inconvenience when fishing on the track. The recommended cost of this engine in St. Petersburg today is 95,500 rubles. - Tohatsu M 9.9 D2
For a long time, we treated Tohatsu PLM with some suspicion, since this brand came to us after such popular names as Yamaha, Mercury, Suzuki and Honda. But over time, the situation changed and even fans of this brand appeared in our country, and some models, for example the two-stroke Tohatsu 9.8 and Tohatsu 18, even became bestsellers. However, we are interested in the 9.9 hp engine. So, its recommended retail price is now 99,300 rubles, but this engine is not available and official deliveries are not expected yet. Therefore, there is no point in describing it in detail. -
And again Mercury! This time we are looking at a new product for 2015 - Mercury 9.9 MH TMC, which, with its appearance in the summer of this year, literally blew up the St. Petersburg market. This engine has several interesting features. The weight of this engine is 41 kg. (exactly the same as the Tohatsu M 9.9 D2), the speed range is 4500-5300 and the combustion chamber volume is 247 cm3. However, the design of the combustion chamber uses loop purge, which provides more smooth work and lower fuel consumption compared to analogues while maintaining excellent dynamics. “Boats-Peter” conducted their own independent tests of this new product, and now boats participating in our sports competitions are equipped with these engines. The Mercury 9.9 MH TMC can also increase power to 15 hp. - our service center provides a similar service. The cost of Mercury 9.9 MH TMC in the Lodki-Piter chain of stores is currently 89,900 rubles, which makes it the most advantageous offer among all other PLMs with a power of 9.9 hp.
