Choosing a hinged engine for a small inflatable boat or canoe always involves balancing power, weight and cost. Hangkai outboard motor 3.6 hpThe squirrel, which is often the first "mechanization" for anglers and those who like to relax on the water, is marketed as a reliable "workhorse" capable of confidently driving a vessel with one or two passengers on board.

The popularity of this modification is due to the simplicity of design, the availability of spare parts and the relatively low consumption of the fuel mixture. However, like any budget unit, it requires the right approach to operation, especially during the primary break-in. Hangkai 3.6 It is a classic two-stroke manually started engine in which it is critical to observe the mixing proportions of oil and gasoline.

In this article, we will analyze the technical nuances in detail, analyze the real specifications and answer the questions that arise from owners immediately after purchase. carburetor and ignition system will help to avoid typical errors and extend the power unit life for many seasons.

Technical specifications and design features

Engine. Hangkai 3.6 It's based on the time-tested architecture of two-stroke, forced air-cooled motors, and the 3.6 horsepower rating is achieved at a crankshaft speed of about 5,500 rpm, which is the optimal mode for displacement. single-cylinderThis greatly simplifies maintenance and reduces the weight of the entire installation.

Special attention should be paid to the ignition system. Here, an electronic CDI (Capacitor Discharge Ignition) is used, which does not require adjustment of the gap and provides a stable spark even when moisture enters. The cylinder capacity is 49 cubic centimeters.This compression allows to develop sufficient traction force for boats up to 3 meters long.

An important element is a lower unit made of corrosion-resistant aluminum alloy, standardized in length at 455 mm, which is suitable for most transverses of inflatable PVC boats. The exhaust system is implemented through a lower unit (under water), which significantly reduces noise and prevents engine overheating by removing hot gases.

💡

When buying, be sure to check the equipment: in the basic version there may be no remote fuel tank, and the engine will work only from the built-in tank.

Fuel system: mixture, flow rate and carburetion

Proper preparation of the fuel mixture is the foundation of a long life for your family. The Hangkai 3.6 outboard motorBecause the engine is two-stroke, the grease of the rubbing pairs (piston group, bearings) is done by oil added directly to gasoline. Using pure gasoline without oil is guaranteed to lead to cylinder bullying and piston wedge in minutes.

For the new engine, it is recommended to use a mixture in the ratio of 1:25 (40 ml of oil per 1 liter of gasoline). After passing the first 10 hours, when the parts are worn, you can switch to a standard ratio of 1:50 (20 ml of oil per 1 liter of gasoline). Gasoline should be used AI-92, since the octane number of AI-95 is achieved by adding alcohols that can aggressively affect the rubber seals of the carburetor.

Carburetation is set by the manufacturer to optimal mode, but the quality of fuel in different regions may require (fine-tuning). The carburetor housing has two main adjustment screws: the quality screw of the mixture (L) and the idle screw (T). Inexperienced users are better not to touch the quality screw unnecessarily, since factory settings are usually the most balanced.

Symptoms of the wrong mixture

If the candle is black and wet, the mixture is too rich (a lot of oil/gasoline). If the candle is white or light gray and the engine is warmed, the mixture is poor (a little oil), which is dangerous for the engine.

The procedure of breaking in: step-by-step instructions

Ignoring the break-in stage is the most common mistake that shortens the life of the engine at times. breaking in Hangkai 3.6 It's necessary to have the piston rings rubbed against the cylinder walls and all the movable parts of the spread lubricated, and it takes about 10 hours to work, but it can be divided into several steps.

In the first hours of operation, it is not recommended to give full gas. The engine should operate in a gentle mode, alternating different turns. This allows you to evenly warm all parts and avoid local overheating. Water for cooling should flow freely, which is easy to check by the jet coming out of the control hole.

During break-in, there is also a primary draw of fasteners. The vibration characteristic of new motors can weaken bolt joints. Therefore, after each release in the first month of operation, it is recommended to check the tightening of the screws of the lower unit attachment to the transom and the cylinder cover.

Table of the main parameters of Hangkai 3.6

To quickly assess the engine's suitability, you can use a performance matrix to help you compare the model to the competition and see if it fits a particular boat.

Weight (with screw) 9.8 kilogram
💡

Weighing 9.8 kg, the Hangkai 3.6 is one of the lightest in its class, which is critical for carrying the engine alone.

Typical malfunctions and methods of their elimination

Despite the simplicity, Hangkai 3.6 The most common complaint of owners is the difficulty of starting after winter storage, often because the carburetor was left with old gasoline, which turned into a resinous substance that clogged the jellyberries.

Another common problem is overheating. If you notice that the engine has lost power or water has stopped coming from the control hole, immediately turn off the engine. The reasons may be because a foreign object enters the water intake or the impeller pump breaks.

💡

Always keep the motor upright. If you put it on your side, the oil from the crankcase can get into the combustion chamber and create an oil plug that will keep the engine from starting.

Spark problems are often solved by replacing the spark plug, it is recommended to have a candle of the NGK BR7HS model or its analogues in stock, and it is also worth (regularly check) the state of the high-voltage wire and cap for oxidation of contacts.

⚠️ Warning: Never try to adjust the L screw (mixture quality) on a warmed-up motor by turning it in the direction of enrichment (counterclockwise) more than half a turn from the factory position, which will lead to a flood of candles and stop the engine.

Real speed and fuel consumption on the water

What can be expected from On a PVC inflatable boat with a length of 2.8-3.0 meters with one adult passenger (about 80-90 kg), the engine confidently accelerates the vessel to 10-12 km / h. This is a speed that is comfortable for trolling or quiet movement between fishing points.

Fuel consumption in this mode is approximately 1.2 - 1.5 liters of mixture per hour. Full built-in tank of 1.2 liters allows you to walk about 40-50 kilometers, which is enough for fishing for the whole day. When the boat is fully loaded (two people plus equipment), the speed drops to 6-8 km / h, and the flow can increase to 1.8 liters per hour.

It is important to understand that Hangkai 3.6 It's not designed to be fully loaded, it needs 5 hp and a boat to go to the plane, but in displacement, it's a very efficient and stable engine.

⚠️ Warning: When transporting a boat with a suspended engine, always remove the fuel hose and develop the residue of fuel from the carburetor to avoid leakage and a fire hazard situation.

Tips for Winter Storage and Conservation

In order to avoid problems with launch in the spring, you need to properly preserve Hangkai 3.6 The main goal is to prevent corrosion inside the cylinder and drying out of the rubber seals, and the first step is to fully generate fuel from the carburetor, so that after the engine stops, shut off the fuel feed and let the engine run until it dies.

Next, lubricate the cylinder. Unscrew the spark plug and pour 5-10 ml of special preservation oil or ordinary two-stroke oil into the candle hole. After that, smoothly pull the starter several times so that the oil is distributed along the walls of the cylinder, and twist the candle back (but do not tighten to the end to avoid condensation).

Where do you store the engine?

The ideal place is a dry room with room temperature. If this is not possible and the engine remains outside, be sure to cover it with a breathable cover to avoid condensation inside the housing under temperature changes.

Keep the motor upright so that the water that has fallen into the lower unit does not freeze or damage the osteoils. Regular prevention and proper storage will allow you to use the engine. Hangkai 3.6 To serve faithfully for many years, remaining a reliable assistant on the water.

Which gasoline is better to use for Hangkai 3.6: AI-92 or AI-95?

The use of AI-95 is not prohibited, but often impractical, since modern additives in high-octane fuel can quickly destroy the rubber elements of the carburetor of budget engines, and you will not notice a power gain at such volumes.

Why does the engine stop at high speeds?

Most often, the cause is a clogged fuel filter in the tank or in the jelly carburetor, and the problem may be a broken tightness of the fuel hose (air suction) or incorrectly adjusting the screw quality of the mixture. Check the cleanness of the fuel tank and the condition of the candle.

Should I change the oil in the gearbox and how often?

Yes, the gearbox oil needs to be changed, the first replacement is done after running (after 10 hours) to remove the metal shavings from the gear grinding, then the procedure is repeated once a season or every 50-100 motor hours, using a special transmission oil for outboard motors (usually green or blue).
