Finding a reliable and affordable outboard motor for a light boat or PVC boat often leads potential buyers to a model known as a “shooter” or “shooter” or “shooter” model. Arrow 5This unit, which is a modified version of the legendary Soviet "Wind", still attracts a lot of interest from fishermen and water lovers. Technical specifications of the outboard motor Arrow 5To see if it can provide the necessary traction and speed on the water.
Compatibility, real gasoline consumption and cold weather ability are key issues in this article, which will take a closer look at the design, compare it to its peers, and give an honest assessment of this two-stroke veteran. 5 horsepower It can be optimal for many tasks, despite the development of electrical analogues.
It is worth noting at once that under the name "Arrow" on the market were supplied engines, structurally almost identical. Wind 5But with a redesign of the casing and some refinements to the ignition system, understanding this pedigree will help you better navigate parts and service features. Let's dive into technical analysis.
Original history and design features
Motor. Arrow 5 The design team did not come from scratch, but was the direct successor to the famous line of two-stroke engines produced in the USSR, and took the time-tested Wind scheme as a basis, changing the appearance of the hood and improving the ergonomics of the roompell, which allowed to maintain high maintainability, making the unit understandable even for those who do not have deep knowledge of mechanics.
A key feature of the design is the vertical arrangement of the cylinder and the use of a lower unit pipe to transfer torque. Two-stroke cycle The engine's performance provides high specific power with minimal weight, which is critical for lightweight craft, and the lack of sophisticated electronics makes the motor immune to fuel quality, which often leaves much to be desired in remote areas.
⚠️ Attention: Despite the simplicity of the design, the engine requires proper breaking in, the first tanks of the fuel mixture must be used at reduced speeds so that the piston group is run without blows.
The cooling system is particularly noteworthy, and it's taken out of the water through special windows in lower unit and fed by a pump built into a lower unit pipe. flow-cooling It is efficient but highly sensitive to the presence of sand and silt in shallow water, and regular flushing of the system with fresh water after operating in salty or contaminated water will prolong the life of the engine.
Why is Arrow 5 like the Winds?
The design similarity is due to the fact that production was often carried out at the same facilities or using identical tooling, the differences are mainly related to the aesthetics of the casing and marking, which makes parts interchangeable in 95% of cases.
Technical specifications and parameters of the engine
To objectively assess the capabilities of the unit, you need to consider its data-sheet figures. Power 5 hp is achieved at certain turns of the crankshaft, and torque is transmitted to the propeller through the gear. The weight of the motor is about 24-26 kg, which allows one person to easily carry it and set it on the transom.
Below is a detailed table that reflects the main engineThis data will help you to match the capabilities of the motor with the requirements of your boat.
| Parameter | Meaning | Unit of measurement |
|---|---|---|
| Power (maximum) | 5 | hp (3.7 kW) |
| Workload | 94 | cm3 |
| Weight with lower unit | 24.5 | kilogram |
| Idle turn | 1000-1200 | min |
| Fuel consumption (max) | 2.2 | l-hour |
It is important to understand that the actual figures may differ from passports depending on the condition of the engine, the quality of the mixture and the load. fuel It depends on how much you open the throttle, and at a cruising speed of about 70-80% of the maximum, gasoline consumption will be well below the limit values.
Power supply system and fuel mixture preparation
The engine is powered by a mixture of AI-92 or AI-95 gasoline and a special two-stroke oil, the mixing ratio is usually 1:25 or 1:30 depending on the oil manufacturer's recommendations and the break-in period. magnifiedTo ensure high-quality lubrication of rubbing vapors.
Using poor-quality oil or disproportionately can lead to catastrophic consequences: a lack of oil will cause overheating and bullying, and excess will cause candles to coking and swelling in the exhaust system. 2T and conform to JASO FD or ISO-L-EGD standard.
The process of preparing the mixture should be in a clean container, first poured gasoline, then added the necessary amount of oil, after which the mixture is carefully shaken. You should not prepare the fuel for the future for several months, because the gasoline loses its properties, and the mixture can be decomposed.
⚠️ Warning: Never store the finished fuel mixture in plastic canisters made from drinking water or industrial liquids. Use only specialized containers with a dense lid to avoid moisture and dust.
Add a fuel stabilizer to the fuel tank if you plan to keep the boat for more than a month, which will prevent the oxidation of gasoline and the formation of resins that clog the carburetor.
Engine start and tiller control
Starting the engine Arrow 5 Before pulling the handle, make sure that the motor is mounted on the transom, the fuel supply is turned on and the air valve is open (if the engine is cold), the jerk must be sharp and confident, but not excessively strong, so as not to damage the starter mechanism.
Control is carried out by turning the hummel, which simultaneously changes the direction of travel and adjusts the engine speed. On the handle of the rummel there is a gas trigger and an emergency stop button ("death button"). When releasing the trigger, the gas must be discharged, returning the engine to idle speeds.
The gearshifting uses a lower unit turn or a special mechanism on the lower unit pipe, depending on the modification. The switching must be done only at idle speeds to avoid breaking the gears of the gears of the gearbox. A sharp transition from full speed back can lead to destruction. coupling.
☑️ Pre-launch checks
Maintenance and typical faults
Regular maintenance is the key to a long life of your engine, the main attention should be paid to the state of the spark plug, the purity of the carburetor and the lubrication of the bearings, the candle should be twisted and checked for the incense every 10-15 hours, the color of the increments will tell you about the quality of the mixture: black indicates a rich mixture, white – a poor one.
One of the common problems is clogging of the fuel ducts and jelly carburetor, which is especially true when using low-quality fuel or storing a full-tank engine in the off-season. carburettor.
Owners also face a leaky crankshaft coil, which causes air suction and impoverishment, which causes overheating. Replacing the coils requires disassembly of the engine and certain skills, so if you suspect it is better to consult a specialist or conduct an audit yourself, having a remix at hand.
⚠️ Attention: If there is a knock or vibration that is not typical for normal operation, operation should be stopped immediately. Further work may lead to the turning of the rod liners and the need for major repairs.
The main reason for the unstable operation of the engine Arrow 5 is a violation of the tightness of the crankcase or clogging of the fuel system, and not the breakdown of the engine itself.
Comparison with competitors and final conclusions
In his class. Arrow 5 The main advantage is the maintenance and ability to repair the engine in the field with a minimum set of tools. Chinese motors often require factory equipment for diagnostics, and electric analogues are limited by battery capacity.
However, Arrow 5 It's a low-level engine that's less noise-efficient and environmentally friendly than competitors, and a two-stroke engine requires mixing oil with gasoline, which creates a characteristic smoke and smell, and for those who value silence on water, this can be a crucial factor in choosing.
So to sum up, this motor is a great choice for fishing, hunting and short-distance cruising, and its simplicity, reliability and availability of parts make it a workhorse that will not fail at a critical moment, if you're willing to put up with noise and smell for reliability and autonomy. Arrow 5 He'll be a loyal helper.
Where can I find the parts?
Arrow 5 and Wind parts are available in most motor and boat stores, as well as online marketplaces, and thanks to unification, there are no problems finding piston groups, carburetors and lower units.
When choosing between a new Chinese brand and a time-tested design, many people prefer it because of its predictability and clear design, a choice of pragmatists who know the price of reliability on water.
Frequently Asked Questions (FAQ)
Which gasoline is best used for Arrow 5?
The best choice is AI-92 gasoline with an octane number of at least 92. AI-95 is allowed, but does not provide significant advantages for the engine of this degree of compression.
Can we use Arrow 5 in shallow water?
You can use the motor in shallow water, but with great care, you need to raise the lower unit to avoid capture of sand and silt by a cooling pump, which will lead to instantaneous overheating of the engine.
How often should you change the oil in the gearbox?
The oil replacement in the gearbox is recommended at the end of each season or every 100 motor hours. The oil should be transparent; if it has become milky, then the sealing of the ossuaries is broken and water has been ingested.
Does Arrow 5 reach speeds of more than 20 km/h?
On a light PVC boat with one passenger, the engine is able to develop a speed of about 20-22 km / h. With increasing load, the speed will fall, and for heavy boats, 5 hp may not be enough to get on plane.
