The water industry in recent years is full of offers from China, and Sharmax Many anglers and water enthusiasts looking for a budget alternative to the famous Japanese brands look to this brand, but before making a purchase, the potential owner is overcome by a natural desire to know what lies behind a beautiful pendant and low price.
Analysis of real-world experience provides an objective view of a product that is often confused with other Chinese copies, and in this article we will examine the technical details, typical “childhood diseases” and hidden resource of the unit, based on data from service centers and the opinions of real users.
It should be noted immediately that Sharmax It is positioned as a universal two-stroke It's popular because of aggressive pricing, but it's a factor that makes you think about the quality of the alloys used and the accuracy of the assembly, and let's see if the savings are justified or if they lead to hidden costs in the future.
First impression: assembly and configuration
When unpacking a Sharmax engine, the first thing that catches your eye is the massiveness of the package. The manufacturer uses dense foam and cardboard, which minimizes the risk of damage during transportation. However, when you look inside, an experienced motorist will immediately pay attention to the quality of the casting of the crankcase and attachments. There are often small influxes of metal or uneven paint, which, however, do not affect the functionality.
The package is usually standard for this segment: the presence of a remote tank, fuel hose, candle key and a set of tools for basic maintenance. Instructions translated into Russian, but the quality of the translation often leaves much to be desired, which can confuse the beginner when setting up the initial setup carburetorIt is important to check for all fasteners, as vibration during transportation sometimes leads to their weakening.
⚠️ Warning: Before starting, be sure to check the tightening of all bolts, especially the mounting of the lower unit and the rample. Factory assembly can be performed in violation of the recommended puffing moment.
The weight of the engine is consistent with the declared specifications, which is a plus for owners of inflatable boats, where every kilogram counts. The plastic of the casing is strong enough, but has the property of scratching when repeatedly handled. In general, the appearance creates a feeling of “workhorse”, which is not expected to be frills, but requires reliability.
Technical specifications and real power
On paper, the Sharmax engine looks attractive for its class. The declared power of 9.9 hp (often with software or mechanical unlockability up to 15 hp, although this depends on the specific modification) allows you to achieve a good speed. carburetor and the quality of the fuel mix.
Many users note that the declared speed is not achieved immediately, requires mandatory breaking in, during which the engine "opens." mineral-oil In the 1:25 ratio, the break-in stage is critical for the longevity of the piston group, and ignoring this rule leads to bullying and loss of compression.
Below is a comparative table of declared and actual indicators based on the measurements of enthusiasts:
| Parameter | Claimed by the manufacturer | Real indicator (average) | Comments |
|---|---|---|---|
| Power | 9.9/15bhp. | 8.5 - 13 hp | Depends on the setting of the jellyphones. |
| Workload | 246 cc. | 246 cc. | Corresponding. |
| Fuel consumption | ~3 l/h | 3.5 - 4 l/h | Full throttle. |
| Weight. | 36 kg | 37-38 kg | With oil and fasteners in mind |
The cooling system deserves special attention. The water pump does its job when driving, but at idle speeds, the jet flow can be weak. This is not a marriage, but a design feature of many two-strokes in this class. The main thing is to make sure that the control jet does not disappear completely.
Use only high-octane gasoline (AI-95) and high-quality two-stroke oil labeled TC-W3. Saving on oil is the fastest way to kill the engine.
Motion dynamics and controllability
How does the boat behave for an outboard motor Sharmax? Owners of PVC boats with a length of 320-360 cm note a confident exit to planing with one person on board. Plunge At low speeds, it's good enough to troll or move against the current, but when the boat is fully loaded, it may not have enough power to plane confidently, and the boat enters transition mode, which increases fuel consumption.
The driveability depends on the installation of the lower unit. The engine has a standard set of adjustments: differentiation and angle of inclination. differentiation It allows you to optimize the position of the boat in the water, and if you set the lower unit too deep, you get excessive resistance, and if you set it too high, you get air capture and cavitation.
Vibration is the Achilles heel of many budget engines. Sharmax is no exception. At idle speeds, vibration is transmitted to the transom and, accordingly, to the boat. As the speed increases, it smooths out, but it does not disappear completely. This is worth considering for those who plan long transitions.
⚠️ Warning: When installing the motor on aluminum boats, be sure to use anti-vibration linings or rubber pads between the lower unit and the transom to avoid resonance.
The noise of the work is also higher than that of the four-stroke counterparts or top two-stroke. two-stroke It's not critical for many fishermen, but those who like silence should consider buying additional noise insulation or using exhaust mufflers.
Typical malfunctions and “childhood diseases”
No technical system is without flaws, and Sharmax The analysis of service statistics and feedback reveals a number of recurring problems: the first and most common is the quality of seals and gums; rubber used in drain can quickly swell or leak, requiring replacement with better ones (for example, Viton).
The second problem is the ignition system: the coil and switch can fail when moisture is injected or overheated, and owners often recommend checking and soldering all available contacts immediately, as well as treating them with water-repellent lubricant. Ignition candle Also requires attention: regular candles often have a low resource and are prone to fouling with soda.
☑️ Diagnosis after the first 10 hours
The third common complaint is that it's difficult to start after a long period of downtime, and that's solved by the right conservation: the discharge of fuel from the carburetor or the use of fuel stabilizers, and the gasoline left in the carburetor evaporates during the season, leaving a resinous plaque that clogs the jellyfish.
The secret of launching "to the cold"
If the engine doesn't start, try to take off the candle, drop 2-3 drops of gasoline directly into the cylinder, twist the candle and sharply pull the starter, which will help to supply the first portion of fuel.
Repairability and availability of spare parts
One of the main arguments in favor of Sharmax is its structural similarity to other Chinese engines (Tohatsu, Hidea, Parsun), which means that it is easy to find spare parts. Piston groups, carburetors, lower units are all mass-produced and available on the market. Repairability High: the design is simple and understandable to anyone holding a wrench in his hands.
Basic maintenance doesn't require a special tool, although having a dynamometer key and flywheel removable will make life much easier. Manuals are easily online because the design is unified, making the motor attractive to those who like and know how to service the equipment themselves.
However, be aware that some parts may not match the size of the donor by 100%, such as the carburettor's pins or thrust lengths, so it is better to focus on the catalog number of a particular model, rather than just the engine size, when ordering parts.
The main advantage of Sharmax is the complete unification with other Chinese engines, which ensures the availability of spare parts even 10 years after purchase.
Final verdict: should I take it?
In summary, we can say that the outboard motor Sharmax He's not a leader in comfort or sustainability, but he's a great leader in his basic function of pushing a boat, and that's the pragmatic choice of putting up with noise and vibration to save money.
If you're looking for a motor for rare weekend fishing trips, don't plan on driving full gas for hours and are willing to monitor its condition, Sharmax is a great purchase. With proper care, it can be as long as 500-700 hours, which is more than enough for amateur use.
However, if you need a motor for commercial use, rental or daily use in harsh conditions, it is better to consider more expensive options with better corrosion protection and build quality, in which case the initial savings can result in frequent downtime and repairs.
⚠️ Warning: Don't try to reach maximum speeds immediately after purchase, let the engine run in a gentle mode for the first 5-10 hours, gradually increasing the load.
Lifehack to extend the life of lower unit
After each exit on salt water, be sure to rinse lower unit with fresh water. Even if the motor did not contact the salt directly, salt mist deposits on the metal and causes rapid corrosion.
Frequently Asked Questions (FAQ)
Which petrol is best used for Sharmax?
It is recommended to use AI-95 gasoline with an octane number of not less than 95. The use of AI-92 is possible, but can lead to detonation and overheating of the engine, especially under load.
Do I need to dilute the oil or pour it into a separate tank?
Sharmax is a classic two-stroke engine, which does not have a separate oil tank (auto-mix system), butter must be mixed with gasoline in a ratio of 1:25 for the new engine (break-in) and 1:50 for the break-in engine, following the instructions for the specific oil.
Can I use Sharmax for trolling?
Yes, the engine has an idling mode that allows you to reach speeds of 3-5 km / h, which is quite suitable for trolling. However, due to the peculiarities of the two-stroke engine and carburetor, you can experience dips when you sharply open the valve after a long operation at low speeds.
Where's the engine number?
The model number and serial number are usually stamped on the plate attached to the engine's lower unit (foot) or directly on the crankcase at the bottom, and a duplicate number is often on the package and on the warranty card.
