Choosing an outboard motor for an inflatable or metal boat is always about balancing budget, reliability and desired speed. In recent years, Chinese manufacturers have taken a strong niche in the boating market, offering affordable alternatives to eminent Japanese and American brands. AllpassEngines that are often sold under various brands or as OEM products.
Many boaters wonder whether it is worth contacting budget models, or it is better to overpay for a proven name. Allpass It has established itself as a supplier of reliable two-stroke and four-stroke units that, if properly maintained, can last more than one season, and in this article we will discuss in detail the technical features, nuances of choice and secrets of long-term service of these devices.
It is worth understanding that behind the external similarity with well-known brands lies its own engineering school and production lines. outboard motor This brand is designed to meet the needs of the mass consumer, where repairability and availability of parts are important, so let's dive into the world of performance and practical applications.
Technical features and engine design
Structurally powertrains Allpass The main focus of production is on ease of maintenance and unification of the units. Two-stroke models are equipped with an efficient lubrication system through the fuel mixture, which requires the owner to strictly adhere to the proportions of oil and gasoline. Four-stroke versions, in turn, have a separate crankcase, which makes them more environmentally friendly and quiet, but requires regular replacement of engine oil.
An important element of the design is the cooling system, and most models use forced circulation of off-shore water through a water pump. impeller (work wheel) is made of high-quality rubber, resistant to abrasion, but its condition must be checked before each season. Overheating of the engine is the main cause of breakdowns, so control of the water stream ("control") is mandatory.
⚠️ Warning: Never start an engine out of water or without a lower unit dipped in water, even for a few seconds. Dry drive instantly disables the glands and pump, resulting in costly repairs.
Carburetor power system in models Allpass It's often based on time-tested solutions, making it easier to set them up, and membrane carburetors are less sensitive to fuel quality and boat position than float-based models, making them versatile for both calm water and light storm use.
Before buying, be sure to check the type of lower unit (legs). For short-transe inflatable boats, it is critical to choose a model with a short leg (S), otherwise controlling the boat will become dangerous.
Assortment of capacities and modifications
The manufacturer offers a wide range of capacities to equip both a small rowing boat and a full-fledged boat. The line begins with compact models in 2.5-3.5 hp, which are ideal for fishing in quiet backwaters or as spare "skids." These babies are light, transportable and economical.
The middle segment is represented by engines with a capacity of 5 to 15 hp This is the “golden mean” for most owners of PVC boats with a length of 280 to 360 cm It is important to choose between two-stroke and four-stroke. Two-stroke engine It will give you a win in speed and dynamics, and a four-stroke - in economy and comfort.
Powerful versions of 18 hp and above are designed for heavy metal boats and boats, equipped with more massive lower units and lift/lower systems, which often feature an electric starter, which makes life much easier with frequent outings.
Selection criteria for different types of boats
Engine selection is not just about buying the most powerful model available, it's about the load capacity of the craft, the type of bottom and the operating conditions. inflatable floor boats (BBBs) or paioles, the total weight of the kit is critical. Allpass It offers excellent lightweight options that do not overload the transom.
If your boat has a rigid aluminum hull, the thrust requirements increase, not only the cylinder volume, but also the gear ratio. For heavy boats, it is better to choose models with an increased gear ratio, which will ensure better thrust at low speeds and allow faster sliding.
When choosing, you should also pay attention to the presence of a speed limiter system and emergency shutdown (check). Security system Check the motor attachment to the transom: the clamps must be powerful, with rubber linings, so as not to damage the side of the boat and securely fix the unit.
☑️ Criteria for motor selection
Rules for running a new engine
The life of any mechanism, especially in an aggressive aqueous environment, depends on the correct running. Many beginners ignore this step, starting the engine immediately at full power, which leads to bullies of the piston group. AllpassAs with other brands, the procedure is mandatory.
The process usually takes about 10 hours of operation or the generation of several fuel tanks, and in the first hours you need to work at low speeds without opening the throttle by more than 30-40%, which allows the parts to get lost in each other, and the rings to take the correct position in the grooves of the piston.
Particular attention should be paid to the fuel mixture during the break-in period. For two-stroke models, it is recommended to slightly increase the concentration of oil in gasoline (for example, make the mixture not 1:50, but 1:40 or 1:35, according to the instructions), This will ensure better lubrication of rubbing vapors at the time of their initial burnishment.
⚠️ Attention: During the break-in it is strictly forbidden to keep the gas handle in one position for a long time. The turnarounds must be constantly varied so that the piston group is erased along the entire height of the stroke.
Maintenance and repair
Regularly providing the assurance that your boat-engine It starts at half-turn at the right time, and the focus should be on changing the oil in the gearbox, before the season starts and after the season ends, before the season is preserved, the oil in the gearbox should be transparent, and if it has become emulsified (like coffee with milk), then the gearbox has got water through the glands.
Ignition plugs are another important element, and their condition will tell you about the quality of the engine. Black soda will indicate a rich mixture or bad oil, white soda will indicate overheating or poor mixture. Always keep a set of new candles, selected according to the caliber number recommended by the manufacturer.
The grease of the friction nodes is also necessary: the rotary screws, the thrust of the gas and the cord of the hummel require periodic application of consistent lubrication, which will protect the metal from corrosion and ensure smooth control.
| Element | Frequency | Action. | Materials |
|---|---|---|---|
| gearbox | Every 50 motor hours | Oil replacement | Transmission oil |
| Ignition plugs | Every 100 motor hours | Cleaning or replacement | NGK/Champion candles |
| Water pump | Once in season 2 | Impeller replacement | Pump kit |
| Fuel filter | Every season. | Replacement/cleaning | Sludge filter |
Why does the engine stop on idle?
A common cause is clogging of the idle jellier or air sucking through the carburetor gasket, and it is also worth checking the adjustment of the screw quality of the mixture.
Common malfunctions and methods of their elimination
Even reliable techniques sometimes require intervention. One of the common problems is the loss of a spark. If the engine doesn't start, the first thing to check is the candle: twist, lean against the mass and pull the starter. If there are no sparks, the problem may be the ignition coil or the switch. On models of Allpass, oxidation of contacts under the flywheel is often found due to moisture ingress, which is treated by cleaning the contacts.
Another problem is overheating, and if the control doesn't hit or hits with a low jet, and the engine is hot, it's probably a clogged cooling system or an impeller that's worn out, sometimes sand or algae get into the pipes, which cuts off the water flow, and then you need to disassemble the lower unit and blow out the channels.
Carburetor problems often involve unstable revs or inability to gain full speed, and this is treated by disassembling and cleaning the carburetor, replacing the membranes. It is important to use quality gasoline with the octane number specified in the instructions, usually this is the first step. AI-92 with the addition of high-quality two-stroke oil.
90 percent of the problems with starting and running the engine are due to the quality of the fuel mixture or the state of the spark plug.
Frequently Asked Questions (FAQ)
Which gasoline is best used for Allpass engines?
It is recommended to use unleaded gasoline with an octane number AI-92Lower quality gasoline can cause detonation, higher quality gasoline (AI-95/98) without proper ignition setting can cause overheating. Be sure to add a special two-stroke oil in the right proportion.
Can the motor be kept upright?
Long-term storage in a vertical position (on a lower unit) is not recommended, as this can lead to the drainage of oil from the gearbox and water entering through the glands. It is best to store the motor horizontally on a special stand or vertically, but on a silencer (if the design allows) or simply on a transducer, lowering lower unit.
How to properly preserve the engine for the winter?
You need to fully develop a fuel mixture from the carburetor (stop on a closed valve), drain the oil from the gearbox and pour new, lubricate all external metal surfaces, close the holes of the carburetor and exhaust, and remove the motor into a dry room.
Where can I find allpass parts?
Parts for these engines are often standardized with other Chinese brands (Hidea, Parsun, Sea-Pro), search for them by catalog number of units or visual matching. Many parts are suitable from the Tohatsu engines of the old series.
