Choosing an outboard motor for a small PVC boat or a compact boat always involves balancing power, weight and price. In the segment of Chinese manufacturers, which have long ceased to be synonymous with poor quality, the brand occupies a special place. HideaModel with a capacity of 9.9 horsepower in the modification Pro This has become a real hit of sales, and there is a simple explanation for this: the constructive possibility of software or mechanical unlocking up to 20 hp This fact is most often sought by potential buyers, studying the outboard motor Hidea 9.9 pro reviews about which flooded thematic forums.
But behind the big twenty-out-of-the-box claims, there is a complex engineering reality that needs to be carefully studied: owners of these units share not only enthusiastic reports of planing under full load, but also warn of the specific nuances of operation that cannot be ignored. Understanding the real picture will help avoid disappointment and make an informed choice in favor of a reliable water assistant.
Design features and technical base
The Hidea 9.9 Pro is based on a time-tested two-cylinder two-stroke circuit that dates back to the legendary designs of Yamaha in the late 90s. It is not just a copy, but a deeply modernized unit in which Chinese engineers have tried to eliminate the known “childhood diseases” of the prototypes. The engine Carter is made of silumin, which provides excellent heat transfer, but requires careful attention to the quality of the assembly and stretching of bolt joints after the first motorcycle watch.
The key difference of the version Pro The standard nine is a modified intake and release system, as well as the presence of an additional lobe valve in the power supply system. As standard, this valve restricts the supply of fuel mixture, preventing the engine from developing full power. Modernization This means removing this restriction, which theoretically doubles the power, although in practice the increase is about 8-9 hp, which, however, is also very noticeable for a light boat.
⚠️ Attention: Changes to the engine design, including the removal of power limiters, automatically remove the product from warranty service.
Engine ignition system Hidea 9.9 Pro An electronic (CDI) that guarantees a stable spark at all speeds and makes it easier to start in cold weather, and an important element of reliability is having a separate oil pump that lubricates rubbing parts regardless of the position of the boat, unlike some budget counterparts, where the lubricant depends on the tilt angle of the lower unit, which is especially critical when operating in shallow water or in sharp maneuvers.
For those who plan long transitions, the fuel tank capacity is an important parameter. A standard 12-liter remote tank that comes with a complete set allows you to travel a considerable distance, but when you force the engine, fuel consumption increases proportionally to the load, so having a transparent fuel pear with a fuel supply indicator is not just convenient, but a necessity for monitoring the system.
Real impressions of operation and dynamics
Analyzing the reviews of real owners, you can get a fairly objective picture of the behavior of the boat with the engine Hidea 9.9 Pro on the water. Most users agree that even in the runoff version 9.9 hp confidently lead to planing PVC boats up to 3.2-3.4 meters with one passenger and minimal cargo.
The situation changes dramatically after unlocking, and the boat with a length of 3.6 meters with two adult passengers begins to plane, reaching speeds of 35-38 km / h. Dynamics It's a very aggressive acceleration, which is especially appreciated when you get out of a hole or overcome a headwave. However, it's worth noting that the "twenty" from the Chinese engine is still not the Yamaha 20GMHS, and miracles are not worth waiting: the safety margin of the nodes remains within the 9.9 hp class.
- 🚀 The maximum speed on a boat 3.6 m with two passengers after tuning reaches 36-38 km / h.
- ⚓ Stability on the course at a wave of up to 0.5 meters is estimated by the owners as high due to the low center of gravity.
- 🔊 The noise level after running and setting the carburetor is reduced to acceptable values that do not interfere with the conversation.
- ⛽ Fuel consumption in trolling mode is about 2.5-3 liters per hour, which is more economical than four-stroke analogues.
It is important to understand that the realization of the potential of the engine depends on the condition of the screw and its compliance with the load. native aluminum screw is often not optimal for forced versions, and owners recommend immediately consider options with a modified pitch or switch to stainless steel for maximum return.
The procedure of modernization: myths and reality
The most talked-about aspect of owning a Hidea 9.9 Pro is the process of turning it into a full 20 forces. There are a lot of conflicting instructions on the Internet, but practice shows that there are two main ways: the first, simpler, is to rearrange the restrictive washer in the fuel supply system or the valve cable, which allows the throttle to open completely. The second way is more complex and requires intervention in the ignition system or replacement of the petal valve.
Many beginners mistakenly believe that it is enough to simply rearrange the cable to get a full 20 hp In fact, without replacing the petal valve with a valve from the 20-strong version (or its revision), the engine will work on a rich mixture, which will lead to coking candles, loss of reception and increased nagaroprostivovovoz. tuning It should be complex so as not to harm the resource of the piston group.
Technical details of the valve group finalization
To perform at high speeds, you need to replace the petals with thinner and more elastic ones, or install a transition plate from 15-20 strong models. Simply removing the limiter often leads to suboptimal engine operation.
It is also worth mentioning the software firmware reflashing of CDI blocks, which is found in newer models. This is the most civilized way of unlocking, does not require physical intervention in the hardware, but it is not available for all years of release.

Fuel consumption and economy
The voraciousness of two-stroke engines is always a hot topic, especially in the face of rising gasoline prices. Hidea 9.9 Pro in the runoff state shows a very moderate appetite. In low-speed trolling mode (2000-2500 rpm), the engine consumes about 2-2.5 liters of mixture per hour, which makes it an excellent choice for fishing, when you need to stay at the point all day without using up all fuel.
When going into planing and driving at full speed, the consumption naturally increases. Forced motor can "eat" up to 6-7 liters per hour at maximum modes, which is comparable to the performance of four-strokes of similar power, but given the fact that the two-stroke is easier and cheaper to maintain. Economy This is achieved by adjusting the carburetor correctly: if the mixture is re-enriched, the consumption will increase by 20-30% without increasing power.
Use fuel additives for high-quality two-stroke engines, which not only prolong the life of the engine, but also allow you to fine-tune the carburetor, reducing fuel consumption and the amount of sunburn on candles.
A clean bottom of a PVC boat and a properly selected propeller can reduce fuel consumption by 10-15%, which in terms of the operating season results in a significant amount.
Reliability, Resource and Typical Problems
When it comes to Hidea’s reliability, there’s a general trend: the build quality of the company’s factories has grown significantly in recent years, and the engines are assembled on automated lines using Japanese and European equipment. reviews Most often, problems arise from violations of the rules of running or using poor-quality fuel.
One of the typical problems of the first hours of operation is the leakage of oil from the glands or stains in the area of the carburetor, this is treated by pulling bolts and replacing the clamps with better ones, and owners note the need to replace regular spark plugs with better ones (for example, NGK), since the complete ones often work unstable and quickly fail.
⚠️ Warning: Never use pure gasoline without oil in the tank. A two-stroke engine will burn in a few minutes. Always follow the mixing proportion specified in the instructions (usually 1:50 for break-in engines).
The resuscitation of the piston group, when properly run and operated without overheating, is 500-700 hours before the first serious intervention. For amateur use (30-50 hours per season), this will be enough for 10-15 years of quiet fishing. The main thing is to prevent the engine from running at full speed in the first 10 hours and regularly check for the presence of a stream of water from the control hole.
Maintenance and preparation for winter storage
The long life of your Hidea 9.9 Pro depends on proper maintenance, the regulation requires candle replacement, inspection of fuel filters and lubrication of the knots every 50 to 100 hours. Particular attention should be paid to the water pump: the impeller is recommended to change every two seasons or when there are signs of overheating, as rubber parts tan and lose elasticity over time.
Preparing for winter is a critical step, and if you just leave the engine with gasoline in the carburetor, you run the risk of coked-up jelly and problems starting by next season, either you have to extract all the gasoline from the float chamber, let the engine stall on your own, or you have to use fuel stabilizers, and you also have to drain the cooling system, so that the engine is put upright and you pull the starter several times.
☑️ Checklist for winter preparations
Keeping the motor upright is best to avoid deformation of the crankshaft coils. If this is not possible, and the motor lies on its side, before the next start it must be kept in the working position for several hours to oil glass in the crankcase.
Comparison with competitors and final conclusions
With competitors like Tohatsu or Mercury, the Hidea 9.9 Pro looks like a "king" (price/quality). For a base price of 9.9 hp from the Japanese brand, you get an actual power of 20 hp, albeit with resource reservations. For those who want to get the most emotion for a minimum budget and are willing to follow the technique, this is the ideal choice.
However, if you want a tool for commercial use, rental or daily operation in harsh conditions without the possibility of repair, it is better to consider the more expensive and conservative brands. Hidea is the choice of a rational user who understands the engine's device and is willing to give it time in exchange for excellent dynamics and low cost of ownership.
Hidea 9.9 Pro is the best choice for those who want to get the specifications of a 20-horsepower engine at a price of 10 hp, provided they are ready for competent running and quality maintenance.
Frequently Asked Questions (FAQ)
Can I unlock the Hidea 9.9 Pro without losing warranty?
Officially, no. Any interference with the design, including removing the restraints, will void the warranty, but some service centers will turn a blind eye to this unless the breakdown is directly related to forcing (for example, a rump broke or a leaky oment leak), but don't risk it: if the piston burns due to a poor mixture after unlocking, the repair will be at your expense.
What is the best gasoline for the Hidea 9.9 Pro?
The manufacturer recommends AI-92 gasoline. AI-95 is possible, but it is not advisable for a two-stroke engine with a low compression ratio, as this can lead to later ignition and overheating. The main requirement is freshness of fuel and quality oil for two-stroke engines (JASO FD or TC-W3).
Do I need to change the screw after unlocking the engine?
The standard propeller is matched to 9.9 hp and has a step that prevents the engine from spinning to cut off. Once unlocked, the engine may not gain momentum under load. Installation of the propeller with a smaller pitch (for example, 9 instead of 11) will allow you to enter the maximum power mode (5500-6000 rpm).
Is the engine warming up at full speed?
With a proper cooling system (clean water channels, whole impeller pump) the body temperature remains within normal limits. However, two-strokes are by definition hotter than four-strokes. If the trickle of water from the control hole becomes weak or hot (soars), the engine must be immediately silenced to avoid bullying.
