Choosing an outboard motor for a PVC boat or boat is always about balancing price, reliability and performance. Hidea 9.9 Pro. Many aquatics see this unit as a budget alternative to the famous brands, but is it so good at real operation? The market is full of marketing promises, and it can be difficult to figure out what is hidden under a plastic casing.
In this article, we will analyze the design features in detail, analyze the real ones. reviews We're not just going to re-examine the specifications from the manufacturer's website, but we're going to focus on the hands-on experience, the challenges of running and the nuances of setting up the carburetor, and that will help you make an informed decision about your purchase.
First of all, it's worth noting that the acronym "Pro" in the model name indicates an upgraded version of the engine, which differs from the basic models with an improved lubrication system and a modified carburetor, and these changes are the most often discussed in specialized forums, and understanding these differences is critical for those who plan to use the equipment in harsh conditions.
Technical specifications and design features
Engine. Hidea HD 9.9 Pro It's based on a two-stroke two-cylinder, and it's a classic solution that delivers great low-speed traction, which is especially important for heavy boats, and it has a displacement of 246 cubic centimeters, which formally allows for power up to 9.9 horsepower. shaft-power It can vary depending on the quality of the fuel mixture and settings.
The ignition system is based on electronic CDI, which eliminates the need to adjust the gap of candles and provides a stable spark even when moisture enters. It weighs about 36 kilograms, making it heavy enough for transport by one person, but at the same time provides good stability on the transom. An important feature is the presence of a forced lubrication system through a carburetor (oil), which distinguishes the Pro-version from simplified modifications.
Water cooling is done through a centrifugal pump located in lower unit, and water is drawn through holes in the bottom of lower unit, and the pump design is considered reliable, but requires regular checks for sand or algae that may disrupt the pump. coolant.
- 🚤 Engine type: two-stroke, 2 cylinders
- ⚙️ Working capacity: 246 cm3
- ⛽ Power supply system: carburetor, 1 carburetor
- 🔄 Launch: manual (traction)
- 🛡️ Protection: engine emergency shutdown system
⚠️ Warning: Unlike the four-stroke engine, this engine requires strict adherence to the ratios of mixing gasoline and oil, and the use of pure gasoline is guaranteed to lead to bullying pistons in the first minutes of operation.
The design of the dayvus involves an anti-cavitational plate, which helps to glid even when the boat is not fully loaded. Shifting is done by turning the ramp, the moves are clear, but require some effort, especially on a cold engine. This is normal for this class of equipment.
Analysis of feedback from owners: pros and cons of operation
By studying forums and communities of hydraulic motors, there are consistent trends in user ratings. Hidea 9.9 Pro It offers a great value for money, and for many fishermen and hunters, this is the parameter that becomes the deciding factor when choosing equipment for seasonal use.
However, there are complaints about the build quality: some users note the need to stretch bolt joints after the first 10 hours of motorized motion, and vibration at idle speeds is also often mentioned, although it is hardly felt on planing. Fuel consumption owners estimate as moderate for two-stroke, but it depends on the driving style.
Noise is particularly noteworthy: At low speeds, the engine is quiet enough, but when you go to full gas, the sound becomes characteristically ringing for a two-stroke circuit. Many users recommend replacing regular screws with better analogues or balancing them immediately after purchase.
- ✅ Affordable price compared to Japanese brands
- ✅ Simplicity of construction and maintainability
- ✅ Good traction at low speeds
- ❌ The need for an initial fastening
- ❌ Noise at high speeds
In general, negative reviews are often not related to design flaws, but to the violation of the rules of running or using poor-quality fuel. Those who approached the operation responsibly, usually happy with the purchase and recommend the engine to friends.
breaking in: rules, stages and typical errors
The process of running is the foundation of a long life for you. HideaMissing this stage or disrupting the technology is almost guaranteed to lead to a decrease in engine life. The manufacturer recommends developing several tanks of fuel mixture with varying oil content, but experienced mechanics advise to approach the issue more conservatively.
The first hours of operation should be at speeds not exceeding 50% of the maximum, during which the piston rings and crankshaft bearings are in use, it is important not to let the engine run at idle speeds for long, as this can lead to the death of the crankshaft bearings. swelling candles and exhaust system.
☑️ Checklist of proper breaking in
A common mistake is to abruptly open the throttle during the burnishing period, which causes local overheating of the CNG parts. temperature If the hand does not tolerate touching the device, then the cooling system is not working properly or the mixture is too poor.
⚠️ Warning: Never turn off a hot two-stroke engine immediately after active operation without first cooling on idles. This can lead to heat stroke and deformation of parts.
After the test is completed, it is strongly recommended to replace the fuel filter and check the state of the spark plug. The color of the soak on the candle will tell you about the quality of the mixture: brick shade indicates the norm, black indicates over-enrichment, white indicates dangerous overheating.
Hidea 9.9 Pro Comparison with Mercury and Tohatsu
On the market. boat-engine Hidea is often compared to the legendary Tohatsu M9.9B and Mercury 9.9. Technically, the Hidea 9.9 Pro is a deep upgrade of older Tohatsu models, as evidenced by the visual similarity of many nodes.
Tohatsu and Mercury both benefit from the stack casting and corrosion treatment, and they tend to have better anodizing, which is critical for salt water, and Hidea requires more care and regular lubrication of the exterior, but Hidea can be a half to two times cheaper.
| Parameter | Hidea 9.9 Pro | Tohatsu M9.9B | Mercury 9.9 |
|---|---|---|---|
| Brand country | China | Japan | United States/Japan |
| Weight (kg) | ~36 | ~36 | ~36-40 |
| Lubrication system | Oil in gasoline | Oil in gasoline | Oil in gasoline |
| Price (orient.) | Low. | High. | High. |
| Resource (hours) | 1000-1500* | 3000+ | 3000+ |
* The resource is indicative, provided you use it properly. In reality, with care, Chinese engines last much longer.
Why is Hidea cheaper?
The secret to low prices is the use of less expensive aluminum alloys for the crankcase and a simplified quality control system at the factory, and logistics from China is cheaper than delivering branded Japanese engines with their complex distribution system. However, this does not mean that the engine is "disposable." With timely maintenance, it lasts for years.
For those looking for a motor for infrequent use (weekends, vacations), Hidea seems a more rational choice. To pay extra for the Tohatsu brand makes sense if the engine is to run in commercial use or in harsh conditions in the north, where reliability is more important than money.
Fuel consumption and economy
Question fuel-flow For a two-stroke engine of 246 cubic meters, the normal consumption is about 3-4 liters of mixture per hour at full gas. At cruising speed (about 3000-3500 rpm), the flow rate drops to 2-2.5 liters. This is quite acceptable for boats 3-4 meters long.
It is worth considering that the actual consumption depends on many factors: the weight of the boat, the condition of the bottom, the height of the engine and the quality of the screw. If the engine does not keep speed and does not enter the planing mode, the consumption can increase, and the engine life can be reduced.
Use only high-quality gasoline AI-92 or AI-95 from proven gas stations. Old gasoline loses its properties after 2-3 months of storage, which leads to problems with the start and unstable operation of the carburetor.
Economy also depends on the right pitch of the propeller: too much stride will force the motor to run in overload mode, consuming more fuel and overheating, too little stride will prevent speed and also increase consumption per unit path.
- 🛢️ Optimal mode: 70-80% of total gas
- 📉 Savings: the use of "economic" screw
- 🔧 Adjustment: adjustment of the carburetor by the color of the candle
Frequent malfunctions and methods of their elimination
Like any technique, Hidea 9.9 Pro The most common problem is clogging of the carburetor's jellyplates, which is due to poor fuel quality or long downtime with the remaining gasoline in the system, and the motor stalls when you try to add gas or does not keep idle.
The second most common problem is the failure of the crankshaft glands, where the motor starts to suck the air, the mixture becomes poorer, and the piston overheats, and the characteristic feature is a whistling sound at the inlet and loss of power, and replacing the glands requires dismantling the crankcase and special tools.
And the owners also have problems with the ignition system, like breaking high-voltage wires or failing the coil, which is not uncommon in damp conditions. Diagnostics is carried out by the method of exclusion: checking the spark on a new candle, checking the compression.
Procedure for failure to launch:1. Check for a spark (twisted the candle, pressed to the mass, pull the starter).
2. check the fuel supply (turn the candle, it should be wet).
3. check the compression (close the candle hole with your hand, pull the starter - it should be perceptibly pushing your finger).
⚠️ Warning: If the engine is jammed, don't try to force it. This will cause the starter cord to break or the ratchet to break. First, find and eliminate the cause of the jamming.
To eliminate most problems, it is enough to have a basic set of tools and a remake of the carburetor. Complex repairs associated with replacing crankshaft or rod bearings are better entrusted to the specialists of the service center.

Can I use the Hidea 9.9 Pro in salt water?
Yes, but with limitations: the aluminum alloys used in Hidea are less resistant to corrosion than their Japanese counterparts; after each outing, the motor must be thoroughly washed with fresh water and all external metal surfaces must be smeared with corrosion-resistant compounds; it is also important to regularly check the condition of the magnesium anode.
Which petrol is better to fill: 92 or 95?
The manufacturer allows the use of AI-92 gasoline, but if possible, it is better to use AI-95 with an octane number of at least 95, which will reduce the risk of detonation and the formation of coal, especially when the engine is under load, the main thing is the freshness of the fuel.
How often should you change the oil in the gearbox?
The first oil change in the gearbox is recommended immediately after running (after 10 motor hours), then the procedure is repeated every season or every 100 motor hours. The color of the oil should be transparent or light brown; if it has become milky, water enters the gearbox, you need to replace the oil oils.
