Choosing an outboard motor for a small PVC boat or a light boat is always a compromise between cost, weight and traction specifications. Hidea 9.8 It is one of the leading engines in the Russian market, and is often seen as an alternative to more expensive Japanese brands such as the Japanese. Tohatsu or YamahaEspecially when the budget is limited and the availability of an electric starter and battery charging is a must.
Many aquatic motorists are looking for information on the request “outboard motor hidea 9.8 reviews”, trying to understand how the claimed 9.8 horsepower corresponds to reality and does not hide the low price of serious design flaws. Yamaha F9.9It's a guarantee of the reliability of the underlying architecture, but the devil, as always, lies in the details of the assembly, the quality of the materials and the adaptation to our operating conditions.
In this article, we will analyze the design, real-world experience in different conditions, from quiet fishing to planing under full load, and discuss typical “childhood diseases” and how to eliminate them.
Technical specifications and design features
Engine. Hidea HD9.8 It is a classic four-stroke unit with vertical cylinders, with a displacement of 212 cubic centimeters, which is standard for this power class, and the design involves two cylinders and a gas distribution system. OHV The overhead valve, which provides good traction at low speeds and stable idling, is a standard engine weight of about 38 kilograms, which is acceptable for carrying by one person, although it requires physical training.
The ignition system in modern versions is most often electronic CDIIt provides a stable spark even when the battery is discharged, although the start is carried out from the battery with a voltage of 12 volts. An important feature is the presence of a forced cooling system with off-board water through the impeller pump. The engine body is made of aluminum alloy coated with multi-layer corrosion paint, but the quality of painting in different lots can vary significantly.
⚠️ Note: When buying, be sure to check the availability of the current certificate of conformity And the seller's stamped warranty card, and there are engines on the market that are imported under gray schemes, which official dealers can only service at full cost.
The motor's tray plate allows for the adjustment of the daydwoot angle, which is critical for putting the boat's correct trim. The screw that comes with the kit usually has a pitch of 9-10 inches, which is the optimal solution for inflatable boats ranging in length from 3.2 to 3.6 meters. For heavier hulls or metal boats, it is recommended to consider installing a screw with a smaller pitch to improve acceleration dynamics.
Analysis of real reviews: pros and cons of operation
By studying powerboating forums and specialized communities, a number of persistent trends in owner assessments can be identified. low-noise The engine is flat, velvet, and especially appreciated when trolling or long transitions, when monotonous hums can be tiring.
The second undeniable advantage is efficiency: the four-stroke scheme burns the mixture more efficiently, and the absence of the need to prepare a benzo-oil mixture makes it easier to operate. Fuel consumption at cruising speed is about 1.5-2 liters per hour, which allows a standard tank of 12 liters to travel considerable distances without refueling. Hidea 9.8 Excellent choice for long-distance fishing trips.
- 🔧 Availability of spare parts: Thanks to the unification with Yamaha engines, it is not difficult to find consumables and parts for repair in Russia, and their price remains democratic.
- ⛽ Economics: Real fuel consumption pleasantly surprises owners who are used to voracious "two-tacters".
- 🔇 Silence of work: No need to keep your hand on the tiller for gas control (due to the cable control system in some trim levels) and low noise.
- ❄️ Winter work: The engine starts confidently even at low temperatures, although it requires quality oil and fresh gasoline.
But the downsides are often the build quality: there are untwisted bolts, the need to tighten connections after the first motor clock, and sometimes the thermostat is not perfect, and some users complain about the tight operation of the tiller gas in the first hours of operation, until the rubbing parts are developed.
For the first 10 hours of operation (break-in), try not to give the engine full load. Work at speeds up to 70-80% of the maximum, periodically changing the modes of operation so that the piston rings fit properly to the walls of the cylinder.
Running and first access to the water
The process of running any four-stroke engine is a critical step in determining the life of the entire power plant. Hidea 9.8 The manufacturer recommends that you work at least 10 hours of motorized energy in a gentle mode, during which the piston rings, cylinders and other moving parts are laundered, and ignoring this stage can lead to increased oil consumption in the future, reduced compression and even bullying.
The first run is best done on a barrel of water, making sure that the control jet cools confidently and continuously, after which the motor can be installed on the boat. In the first hours, you should not go above 30-35 km / h and not go to the plane with full load. The engine must operate in a variety of modes: idle, medium rpm, short-term acceleration.
It is important to monitor the engine temperature. To the touch the cylinder head should be hot, but not burning. If the engine goes into overheating (boiling), you need to immediately discharge the gas and check the cooling system. Often the cause is the entry of debris into the water intake or a malfunction of the impeller pump.
☑️ Checklist before first launch
After the first 10 hours of operation, it is mandatory to maintenanceIt involves replacing the engine oil, and in the process of running in the oil, metal shavings from rubbing parts get into the oil, so you can't leave this dirt in the crankcase, and it's also recommended that you check the tightening of all screw joints, especially the fastening of the datawoot to the engine compartment and the screw nut.
Comparison with competitors: Hidea, Tohatsu, Yamaha
To objectively assess the place Hidea 9.8 In the market, you have to compare it to the direct competitors. Tohatsu M9.8B and Yamaha F9.9Japanese brands are traditionally known for their flawless build quality, perfect fitting of parts and high reliability of electronics, but their cost can be 1.5-2 times higher than that of the Chinese counterpart.
Hidea It can have a little more backlash in plastic casings, a little bit more coarse aluminum casting, but its main function is to pull the boat, and it does as well as the big brands. Motul or Liqui Moly) and the installation of a new candle (e.g., NGKThe engine is almost indistinguishable from the Japanese.
The table below shows a comparison of key specifications:
| Characterization | Hidea HD9.8 | Tohatsu M9.8B | Yamaha F9.9 |
|---|---|---|---|
| Workload (cm3) | 212 | 169 | 212 |
| Weight (kg) | ~38 | ~36 | ~38 |
| Launching system | Manual/Electric. | Manual | Manual/Electric. |
| Approximate price (ruble) | Budgetary | Medium+ | Premium |
⚠️ Warning: Do not try to programmatically "swell" the engine to 15 hp without replacing the carburetor and exhaust system. This will lead to overheating of the piston group and reducing the engine life at times.
Typical malfunctions and methods of their elimination
Despite the reliability, there can be problems in the operation, and one of the most common complaints is that it is difficult to start or unstable idle, often due to poor fuel or clogging of the carburetor's jellyplants. fuel-washing and replace the fuel filter that is inside the float chamber.
Another common problem is overheating. If the control jet has become weak or disappeared, you need to check the condition of the impeller water pump. Rubber blades wear out or tan over time, especially if the engine has been without water for a long time. Replacing the pump is a simple procedure and does not require special tools, except for a set of keys and a new impeller.
Problems with gear shifting (crunch, knocking out) are often solved by adjusting the switching cable or replacing the slips. It is important to use the right lubricant for the datadvut and regularly change the oil in the redtor, checking for the presence of an emulsion (a sign of water entering through the glands).
How do you prolong the life of Daydwood?
To protect the lower unit from corrosion and fouling, it is recommended to wash the engine with fresh water after each exit into salt water. Also, once a season, lubricate the splints of the paddle shaft with a special lithium grease that is resistant to washing.
Fuel consumption and economic efficiency
The question of efficiency is one that every boat owner has to face. Hidea 9.8 It consumes much less fuel than two-stroke engines of similar power. In trolling mode (3000-3500 rpm), the flow is about 1.2-1.5 liters per hour. When driving half-stroke (about 25-30 km / h), the flow increases to 2-2.5 liters.
The maximum consumption (about 3.5-4 liters) is observed when going into planing and driving at full speed, but in this mode the engines are rarely and briefly operated, the economic effect of using a four-stroke becomes noticeable after 10-15 motor hours, especially given the current prices for gasoline and oil.
Also, a four-stroke engine doesn’t require buying expensive two-stroke oil and mixing it in proportion: You pour pure AI-92 gasoline (or AI-95, preferable for modern engines) into the tank, and the oil changes only in the crankcase once a season or every 100 motor hours.
The Hidea 9.8 four-stroke pays off its cost for 2-3 seasons of active operation solely due to fuel savings and no need to buy oil for the mixture.
Summary: Is it worth buying?
Summing up the review, it can be said that Hidea 9.8 It's a great choice for anglers and water enthusiasts looking for a reliable, economical and inexpensive motor, and it's not without the disadvantages of the budget segment, but it's easy to fix and doesn't affect the overall reliability of the design. It's a workhorse that, if properly maintained, will last for many years.
If you're willing to put up with a little more weight than two-strokes and pay attention to regular maintenance, this motor will be a faithful assistant on the water. It confidently puts inflatable boats up to 3.6 meters long with one or two passengers and cargo on the glise, ensuring a comfortable and quiet ride.
Do I need to change the oil in the new Hidea engine?
Yes, manufacturers recommend replacing factory oil after the first 5-10 hours of operation (break-in period). Factory oil may contain parts grinding products, and replacing it will significantly prolong the life of the engine. Use oil with a viscosity of 10W-30 or 10W-40 with a tolerance for four-stroke outboard motors.
Which gasoline is better to pour: AI-92 or AI-95?
The Hidea 9.8 engine is designed to allow the use of AI-92 gasoline, but the use of AI-95 with an octane number of at least 95 (Research) is preferable, as it provides more stable combustion, less scaling and reduces the risk of detonation, especially in hot weather or under load.
Can I install an electric starter on Hidea 9.8 if I don’t have one?
Structurally, many Hidea 9.8 models have prepared places for the starter, but in the basic configuration (manual start) the starter itself, the battery and the corresponding wiring may not be. Installation of an electric starter is possible, but will require the purchase of the starter itself, the battery, the rectifier-regulator and wiring, which is not always economically justified.
How often should you change the oil in the gearbox?
The gearbox oil is recommended to be changed once a year or every 100 motor hours. When used frequently in difficult conditions (sand, silt), it is worth checking more often. If the oil has acquired the color "coffee with milk", then the leakage of the ods is broken and the water has got into the gearbox - immediate repair is required.
