Finding a reliable and affordable engine for small mechanization is a challenge faced by every angler or small boat owner. Hey, 22.It's a modern alternative to the older Japanese, and if you're planning to buy a Hi 22 outboard, you need to be very knowledgeable about its design features, because it's not just a copy, it's a product with its own specific engineering.
In this article, we will conduct a deep analysis of technical parameters, consider the real possibilities of the unit and discuss the feasibility of purchasing it in the current market conditions. It is important to understand that buying such equipment is an investment in long years of operation, so superficial acquaintance with advertising brochures will not be enough to make an informed decision.
We will discuss in detail how this engine differs from competitors, what modifications exist and what to look for when choosing a seller. Competent approach to choosing will avoid common mistakes and save the budget that can be spent on quality fuel or additional attachments.
Technical specifications of the model Hi 22
Engine. Hey, 22. It is a two-stroke petrol unit designed to meet the demands of modern water systems of various types, based on a single-cylinder air-cooled internal combustion engine, which greatly simplifies the design and reduces the weight of the entire mechanism, and the power of 22 horsepower is achieved by optimizing the cylinder purging and adjusting the carburetor.
The engineers have focused on the ignition system, and it uses an electronic system. CDIThis is critical for starting the engine after long downtime or in wet weather, when traditional contact systems often fail.
The engine weight is about 45-48 kilograms, making it easy enough to fit on the transom of an PVC inflatable boat or a small aluminum boat, but it should be borne in mind that for a full plane with such power, a boat at least 3.5 meters long and minimal loading is required.
To extend the life of the piston group, use only high-quality two-stroke oil labeled TC-W3 in the ratio of 1:50, specified in the instructions.
Technical parameters directly affect the performance of the vessel. Below is a table with the main specifications that will help you compare this model with other options in this power class.
| Parameter | Meaning |
|---|---|
| Power | 22 hp (16.2 kW) |
| Workload | 346cc |
| Maximum speeds | 4500-5500 rpm |
| Type of fuel | AI-92 + butter |
| Recommended transom | 40 mm |
Design features and reliability of nodes
When deciding to buy a outboard motor, many users pay attention to the materials of the manufacture of the main components. The engine Carter is made of aluminum alloy, which ensures good heat transfer and resistance to corrosion. However, like any equipment of the budget and medium segment, there are nuances that require the attention of the owner.
The cooling system is built on a classic scheme with water intake through a water intake in lower unit, an important element is the impeller pump, which is made of rubber with increased elasticity. Piedfish sensitive to work "on dry", so it is strictly impossible to start the engine outside the water or with a blocked control hole.
⚠️ Warning: Be sure to check the condition of the lower unit coils before each season. Their timely replacement costs a penny, but saves the gearbox from expensive repairs in case water gets inside.
The carburetor fuel supply system is set up in the factory, but the quality of Russian gasoline often requires additional adjustment of idling. To access the jelly and screw quality of the mixture, you need to remove the top casing, which is done quite simply with a standard set of tools.
The transmission unit uses a conical gear to transfer rotation to the propeller shaft. The gear ratio is selected to ensure optimal torque on the propeller. The propeller that comes with the kit usually has a pitch suitable for universal operation, but for heavy boats it is better replaced with the option with a smaller pitch.
The Secrets of Longevity (Durability)
The engine life depends on the quality of the assembly. Before the first operation, it is recommended to stretch all the threaded connections available, since during transportation, vibration could weaken the fastener.
Where to buy and how not to run into a fake
The question of where to buy a outboard motor is especially acute today, given the number of unscrupulous sellers in the market, official dealers provide warranty and service support, but their prices can be higher than those of private dealers or marketplaces, but savings of 10-15% can result in a lack of spare parts in the event of a breakdown.
When buying in an online store, be sure to require a product passport and a filled-in warranty card with the seller's seal. The lack of documents is a sure sign that you are either counterfeit or an engine recovered from used nodes. The serial number on the crankcase of the engine must match the number in the documents.
Also worth paying attention to the equipment. The complete set should include: the engine itself, the remote tank (if provided with a modification), the screw, a set of keys, a spark plug and instructions. If the seller tries to sell a "naked" engine without a screw or a lower unit, this is reason to doubt his honesty.
Regional distribution features also play a role: In remote regions of Siberia and the Far East, models with an adapted launch system for cold climates are common, and check with the seller whether a particular batch is intended for operation in your climate zone.
Operation and first launch: tips for beginners
Once you've been able to buy a Hi 22 outboard motor and get it to the point of use, the most critical step is running in, and many people ignore it as a formality, but it's running in the right way that determines 80 percent of the life of the piston group. A two-stroke engine requires the rings to be lapped against the cylinder walls at a gentle temperature.
The first run is better done on land, in a barrel of water or on a special stand to make sure that the cooling system works. Make sure that there is a confident stream of water from the control hole (the "urinal"). If the water does not go, immediately shut down the engine, otherwise overheating will lead to bullies.
The break-in process takes about 10 hours. It's not recommended to give full gas in the first hours. The optimal mode is to operate at 30-50% power with periodic short-term speed increases. This allows you to evenly distribute the oil over the rubbing surfaces.
For the convenience of users, we have prepared a checklist of actions before the first launch, following these points will help to avoid the typical mistakes of beginners.
☑️ Preparations for first launch
Comparison with competitors: Tohatsu, Yamaha, Hidea
There are many analogues in the market, and the potential buyer often fluctuates. Tohatsu and Yamaha They're Japanese classics, known for their reliability, but they're now much more expensive. Hidea or Parsun offer similar specifications, but are often inferior as casting and anticorrosion protection.
The Hi 22 model benefits from the availability of spare parts and adaptability to Russian fuel. While it is sometimes difficult to find original remixes for Japanese engines of the old model, consumables are available in any specialty store for domestic assembly.
But when it comes to noise and vibration, Japanese engineers are still ahead. Hello 22 can be more noisy at high speeds, which is offset by lower entry costs and lower maintenance. For fishing, where silence is important, this can be a deciding factor.
Also worth noting is the repairability: the Hi 22 design is simple enough for an owner with basic technical skills to do minor repairs on their own, and complex electronics and unique nodes are virtually absent, making it easier to diagnose in the field.
Choosing between brands is always a trade-off between price, reliability and cost of ownership. Hi 22 is a choice in favor of economy and maintainability.
Frequent malfunctions and methods of their elimination
Like any machine, the engine can fail. Most often, owners have problems with ignition or fuel supply. If the engine does not start, first check for a spark. Unscrew the candle, press it with threads to the mass of the engine and pull the starter. If there are no sparks, the problem is in the coil or switch.
The second common problem is clogging of the carburetor, and if the engine stalls when you add gas or if you don't keep idle, you're probably clogged with jelly, you're going to have to wash it in the carburetor cleaner or blow it with compressed air, and using fresh fuel minimizes that risk.
Knocking at the bottom of the lower unit may indicate a backlash of gear gears or bearings, and operating the motor with such a malfunction is prohibited, as it can lead to jamming of the shaft and destruction of the gearbox body, in which case the bearings and glands are required to be replaced.
⚠️ Warning: Never keep an engine full of gasoline in an enclosed space without draining fuel. Gasoline vaporization is explosive, and old gasoline loses its properties and forms resins.
Diagnosing complex malfunctions, such as loss of compression, requires a compressometer, which is a normal compression of 8-10 atmospheres, and a significant drop in this indicator indicates wear and tear of the piston group or rings.
FAQ: Answers to Frequently Asked Questions
Which screw is better to put on a PVC boat with a length of 3.8 meters?
For a boat 3.8 meters long with a 22 hp engine, a standard aluminum propeller with a pitch of about 9-10 inches is optimal. If the boat is heavily loaded, you can try a screw with a smaller pitch to improve thrust, but this will reduce the maximum speed.
Do I need to register the Hi 22 engine in the GIMS?
Under current Russian law, registration is required for small vessels with an engine of more than 8 kW (approximately 10.8 hp). Since the power of Hello 22 is 22 hp (about 16 kW), registration and the availability of rights category "M" is mandatory.
Can this motor be used in salt water?
Aluminum alloys are susceptible to corrosion in salt water, and after each outing, the engine must be thoroughly washed with fresh water, paying special attention to the cooling system and external surfaces.
How often should you change the oil in the gearbox?
It is recommended to replace the oil in the gearbox after the first 10 motor hours (after running), and then every 50-100 motor hours or once a season, before winter storage. The oil should be transparent; if it has become milky, then water has entered the gearbox.
