Choosing an outboard motor for a small boat or boat often becomes a compromise between the desired speed and the legal constraints. Hidea 9.9 Pro It occupies a unique niche, offering specifications that formally remain within the registration rules but actually allow speeds comparable to those of the more powerful analogues, and is designed to meet the requirements of reliability and economy, making it popular among anglers and PVC boat owners.
The main feature of the model lies in its technical implementation: with a nominal passport power of 9.9 horsepower, the engine is structurally able to produce specifications close to 15-horsepower models, this is achieved due to increased cylinder volume and an optimized fuel mix system. Hidea 9.9 Pro features The system, which allows you to bypass the restrictions on registration in GIMS, becomes an ideal solution for seasonal operation.
In this article, we will discuss in detail the technical parameters, design features and real capabilities of this engine. Hidea It will help you make an informed decision about the purchase and properly maintain the equipment throughout its life.
Technical specifications of the engine
Engine. Hidea 9.9 Pro It is based on a proven two-stroke circuit that provides high specific power at a minimum weight, with a cylinder capacity of 246 cubic centimeters, which is a significant indicator for this class of engines, and an electronic ignition system (CDI) that guarantees stable spark formation at all rpms and facilitates start-up in the cold season.
Fuel efficiency is the most important parameter for any owner. Despite the high power for its class, the engine shows a moderate appetite. The average fuel consumption when driving at full-traction is about 3-4 liters per hour, which allows you to comfortably spend on the water all day with one tank of 12 liters. However, it is worth considering that the real consumption depends on the load on the screw and the condition of the transom.
To run a new engine, use a fuel mixture with an increased oil share (1:25) in the first 2-3 tanks, even if the instruction allows for a 1:50 standard at once.
The cooling system is based on the principle of forced circulation of off-shore water through a water pump. The pump's wing is made of high-quality rubber that is resistant to abrasion, but requires regular inspection, especially if you often walk in shallow water or overgrown water bodies. carburetor and the piston group.
- ⚓ Engine type: Two-stroke, 2 cylinders
- ⚓ Working capacity: 246 cm3
- ⚓ Ignition system: Electronic CDI
- ⚓ Cooling system: Forced, water-based
- ⚓ Type of fuel: AI-92 petrol with oil
Design features and reliability
The engine body is made of aluminum alloy coated with anti-corrosion paint, and engineers have put a lot of emphasis on protecting the internal components from salt water, which makes it possible to do this. Hidea 9.9 Pro It is suitable for use not only in freshwater, but also in the sea, provided that it is washed in a timely manner. The design of the daydwoot is strengthened, which reduces the risk of damage from accidental impacts on underwater obstacles.
One of the key features is that there's a forced lubrication system in the crank-shaft mechanism, and unlike the cheap Chinese, where the lubrication is done only by the oil in gasoline, there's a more advanced scheme here, which reduces friction and increases resource levels. bearing The carburetor is very stable and rarely requires intervention after the initial break-in.
⚠️ Warning: Despite the protection, do not specifically try to ram drifters or stones at high speed. A hit can cause the shafts to shift and the destruction of the daydvut, which is not a warranty case.
The rompel control in this model is ergonomic and convenient. The gas lever has an idle lock, which makes it easier to warm up the engine. The rompel also has an emergency stop button (safety rope) that must always be connected to the operator's clothes. The gearshift mechanism (forward-neutral-back) has clear locks that prevent spontaneous shutdown of the transmission under load.
Productivity and speed quality
The main question that interests potential buyers: what speed develops Hidea 9.9 ProThe answer depends on a variety of factors: the weight of the boat, the number of passengers, the type of propeller and hydraulic compensator. On a standard PVC boat with a length of 3.2-3.6 meters with one person on board, the motor is able to accelerate the vessel to 28-32 km / h. This is an excellent indicator for trolling or fast movement between fishing points.
When installed on light aluminum boats ("Kazanki" or their modern analogues) with a flat bottom, the speed can reach 35-38 km / h. However, it is important to be careful: the plane output should be smooth, so as not to overload the transom. The engine has a good traction force at low speeds, which is critical for fishing in windy weather or against the current.
It is worth noting the work on single turns. Hidea 9.9 Pro It keeps its speed low, allowing it to be used efficiently for trolling without the need for additional equipment, and if even lower speed is required, many owners use the method of "bending" the bumper or installing a special stop, although the plant does not recommend this.
- 🚀 Maximum speed (PVC 3.2m): up to 30 km/h
- 🚀 Time of exit to planing: 15-20 seconds
- 🚀 Optimal cruising speed: 20-25 km / h
- 🚀 Consumption on trolling: less than 1.5 l / hour
Comparison with competitors and modifications
There are many analogues on the market, but Hidea 9.9 Pro It is often compared to Tohatsu and Mercury engines because they are structurally very close, and Hidea’s main advantage is that it is more affordable while maintaining high build quality, while it outperforms many low-end Chinese brands in terms of aluminum casting quality and precision in parts processing.
There is also a modification with an electric starter, but the classic handcuff is considered more reliable and lightweight. Many users note that after a little modification (replacing the screw with a faster or more loaded) the specifications of the engine change dramatically.
The secret of the popularity of the model
Why do everyone choose 9.9 hp? The fact is that engines up to 10 hp inclusive in many regions do not require registration in the GIMS and do not need the rights to operate a small vessel, if the power of all engines on the boat does not exceed 8 kW. This saves the owner from annual tax and inspection.

Service and preparation for the season
Durability Hidea 9.9 Pro Two-stroke engines are extremely sensitive to oil quality; use only special oils for outboard motors labeled TC-W3; use of automotive oils or cheap analogues will lead to the formation of soot on candles and exhaust windows.
Before each season, you need to check the state of the spark plug, clean the water holes of the daywoot from the algae and check the lubrication level in the gearbox. The oil in the gearbox is recommended to change once a season or every 100 motor hours. If the color of the oil has turned milky, this is a signal that water enters through the glands, which requires immediate repair.
☑️ Season preparation checklist
⚠️ Warning: Never keep a full tank of gasoline indoors, gasoline vapors are heavier than air and can build up below, creating an explosive situation, drain the fuel or use a stabilizer for long-term storage.
Frequent malfunctions and their elimination
Even the reliable Hidea It can be a problem if you're not operating properly. One of the most common problems is having trouble starting. Most often it's because of old fuel or a misalignment of the mix. If the engine sneezes and dies, first check the candle, and if it's wet and black, it means the mixture is too rich or too weak a spark.
Another common problem is overheating. If you notice that the control hole stopped running water, immediately turn off the engine. Drying for even a minute can lead to piston scuffs. Usually the cause is a failure of the impeller pump or a foreign object getting on the water intake. Regular visual inspection of the water jet is a mandatory procedure.
Vibration at high revs can indicate damage to the screw or imbalance. The bent blades of the screw not only reduce speed, but also create a dangerous load on the lower unit. Always carry a spare screw and a set of tools to replace it.
Timely replacement of fuel filters and use of high-quality mixture – 90% of success in the smooth operation of the two-stroke engine.
Final evaluation and recommendations
Hidea 9.9 Pro It has established itself as a workhorse for outdoor water enthusiasts, and its combination of high power (actually 15 forces), low weight and affordable price makes it one of the top sellers in its class, ideal for those who want to avoid the bureaucracy of check-in but are not willing to sacrifice speed and comfort.
The engine requires careful preparation of the mixture and regular lubrication, but in return gives years of stable service. If you are looking for a reliable unit for fishing, hunting or cruising with your family at short distances, the specifications of this model fully justify the investment.
Storage board
When you put it in winter storage, be sure to blow out the carburetor, and then you run out of fuel, so close the fuel tap, and let the engine run until it stops, and that prevents the chicklers from souring in the winter.
FAQ: Frequently asked questions
Do I need to register Hidea 9.9 Pro in GIMS?
Under current Russian legislation, small vessels with outboard motors of more than 8 kW (approximately 10.88 hp) are subject to registration. Hidea 9.9 Pro It is 9.9 hp (about 7.3 kW), and the engine itself does not require registration. However, if the boat weighs more than 200 kg, registration may be required.
Which oil is best used for the mixture?
Use only oils for two-stroke outboard motors marked TC-W3. The recommended ratio for running is 1:25 (40 ml per 1 liter of gasoline), for normal operation - 1:50 (20 ml per 1 liter). The use of oils for chainsaws or motorcycles (JASO FD / FE) is allowed as a last resort, but they give more scorching and burn worse in aquatic environment.
Why does the engine stop at high speeds?
Most often this is due to a violation of the fuel supply (a jet lag, a filter in the tank clogged) or a violation of the ventilation of the tank (tighten the tank lid or, conversely, check the valve), also the cause may be in the "overheating" of the candle or improper adjustment of the carburetor. Check whether the motor sucked excess air through the gaskets.
Can I put a screw with a large pitch for speed?
Theoretically, it can, but it's dangerous for the engine, and if you put a speed rotor on a motor that's not designed for such loads, you'll get the engine running in overload mode, overheating and quickly failing the piston group, and you'll want to leave the standard propeller or you'll have to match the pitch recommended by the manufacturer for the power.
