Parsun Power Machine Co., LtdZhuhai is one of the brightest representatives of this rapid growth, offering the market a wide range of products. If you are wondering what engines Parsun produces, the answer covers almost all market segments, from compact electric motors for pleasure boats to powerful four-stroke units for professional use.
Today, the company's products Parsun It is known all over the world and is often assembled on the same production lines with well-known European brands, which guarantees high build quality. Engineers focus on reliability, environmental friendliness and adapting engines to different operating conditions, whether it is salty sea water or muddy river ducts. In this article, we will analyze in detail the model series, technical features and key differences between series to help you make the right choice.
History of development and production capacity of the plant
Established in 2002, the company Parsun Originally specialized in two-stroke engines, copying the time-tested designs of Yamaha and Tohatsu. However, over time, the company invested huge funds in its own research and development centers (R&D), which allowed to move to the creation of original components and assemblies. Today, the plant is a high-tech complex with fully automated assembly lines and strict quality control at every stage.
The production capacity allows to produce hundreds of thousands of units of equipment per year, with a significant part of the products exported to more than 100 countries. Parsun It's not just building motors from the parts it buys, but it's making key components on its own, including carburetors, ignition systems and even cylinder blocks, giving the company full control over the cost and quality of the final product.
The modern factory is equipped with advanced test benches, where each engine is tested under load before packaging, an approach that has allowed the brand to establish itself as a manufacturer offering the best value for money and reliability. A unique feature of the Parsun production line is the modular assembly system, which allows you to quickly adapt the engine design to the requirements of specific markets, for example, changing the environmental settings to EPA or CE standards.
Two-stroke engines: T series and standard models
Two-stroke engine lineup Parsun It remains one of the most popular PVC inflatable boats and small aluminum boats, valued for its lightness, ease of maintenance and ability to quickly develop maximum power. The range starts with compact engines with a capacity of 2.6 hp and reaches serious 40-horsepower units that can bring to the sleeve of rather heavy boats.
In the design of two-stroke Parsun uses modern technologies, such as loop blowing of cylinders, which ensures a more complete combustion of the fuel mixture and reduces gasoline consumption compared to outdated analogues. CDI (Capacitor Discharge Ignition) guarantees stable start of the engine in all weather conditions, and the presence of a thermostat in the cooling system protects the engine from overheating during prolonged operation at high speeds.
Special attention should be paid to the series. T (e.g. T9.8, T15, T18), which is an improved version of standard two-strokes, these motors are equipped with a forced lubrication system, which eliminates the need for manually mixing oil with gasoline, the oil is poured into a separate tank, and the electronics dose its supply depending on the engine speed.
- 🚤 Series T: Equipped with an oil mixing system, which simplifies operation and reduces exhaust smoke.
- ⚓ Standard seriesClassic two-strokes, requiring the preparation of a fuel mixture, are distinguished by maximum simplicity and maintainability.
- 🔧 UniversalityAll two-stroke Parsun engines have a standard fit on the lower unit, which makes it easy to change the units of different manufacturers.
- 💨 Ease of easeTwo-stroke models are much lighter than four-stroke counterparts, which is critical for small boats.
⚠️ Attention: When using standard two-stroke engines without a mixing system, strictly monitor the proportion of oil and gasoline. Using pure gasoline will lead to bullying of the piston group and the engine will fail within a few minutes.
Secrets of running a two-stroke engine
The first 10 hours of operation, the engine should run at a speed of no more than 50% of the maximum. This is necessary for laundry of piston rings and crankshaft bearings. Don't hold the gas handle in one position for a long time - periodically change turns.
Four-stroke engines: F and HD series
Four-stroke engines Parsun The range of four-strokes covers a power range from 2.5 hp to 100 hp or more. The main difference from two-stroke analogues is the presence of a full-fledged gas distribution mechanism and a separate engine lubrication system, which eliminates the need for mixing fuel with oil.
Series F (e.g., F5, F9.8, F20) are classic low camshaft (OHV) four-stroke engines that are robust, low in noise and vibration, ideal for trolling because they can work at low speeds without the risk of candle contamination, and use 30-40% less fuel than two-stroke engines of the same power.
For more demanding users and commercial use, the series is designed to be HD These engines are equipped with additional protection systems, reinforced components of the shaky piston group and improved cooling system. In high-power models, electronic fuel injection (EFI) is often used, which improves combustion and engine responsiveness.
An important advantage of the four-stroke Parsun engines is their environmental friendliness, they meet strict international emission standards, making them permitted for use on water bodies with special conservation status, and the exhaust system and silencer are carefully designed to minimize noise, which is highly appreciated by fishermen.
When choosing between two-stroke and four-stroke engines, consider frequency of use. If the boat is on the water all summer and is used often, a four-stroke will save you a lot of money on fuel. For rare weekend trips, a two-stroke will be more practical because of weight and price.
Specialized Series: Electric and High Performance Motors
Factory Parsun Parsun's electric motors are designed to be used as auxiliary engines for trolling or as the main propulsion system in small waters where noise and exhaust are prohibited. They are characterized by silent operation, no vibrations and easy control.
In the high-capacity segment, the company offers engines with remote control and lower unit hydraulic lift. Parsun F100 or F115They are equipped with multi-cylinder units (inline four), an electronic fuel injection system and a 2.08:1 gear ratio, which allows efficient use of large diameter screws, which ensures excellent low-speed traction and high maximum speed.
The Long Shaft is designed to be fitted to high-transnance vessels, and the plant produces both standard lower unit (381 mm) and elongated (508 mm or more) modifications, which allow the same engine to be adapted to different types of boat and boat hulls.
- ⚡ Electric motors: Operate from 12V or 24V, have a telescopic rummule and several speed modes forward and backward.
- 🚀 High power.: Models over 60 hp are equipped with an electric starter and battery charging.
- 🌊 AdaptationThe presence of anti-cavitation plate of a special shape improves the driving qualities of the boat.
- 🛡️ ProtectionAll engines have dry-operated protection and an emergency stop system.
⚠️ Attention: When installing the motor with an elongated lower unit on a boat with a short transom, the anti-cavitation stove should be submerged by at least 100 mm. If the stove is higher, air capture, overheating and loss of traction will occur.
☑️ Check before buying the engine
Comparative table of technical specifications
To compare the main specifications of different series of engines Parsun Please note that the specifications may vary slightly depending on the year of production and the specific modification of the engine.
| Parameter | Parsun T9.8 (2T) | Parsun F9.8 (4T) | Parsun F20 (4T) | Parsun F60 (4T EFI) |
|---|---|---|---|---|
| Type of engine | two-stroke | four-stroke | four-stroke | four-stroke EFI |
| Power (hp) | 9.8 | 9.8 | 20 | 60 |
| Workload (cm3) | 169 | 197 | 362 | 964 |
| Weight (kg) | 26 | 38 | 45 | 110 |
| Lubrication system | Mixture/auto | Separate | Separate | Separate |
As you can see from the table, four-stroke engines have more weight because of the more complex design of the cylinder block and the presence of an oil crankcase. However, they benefit in fuel consumption and comfort level. T9.8 It is considerably lighter, making it a preferred choice for lightweight inflatable boats, where every kilogram on the transom affects differentiation.
Maintenance and reliability of operation
One of the key issues that owners are concerned about is the reliability of Chinese engines and the availability of spare parts. Parsun It uses unified components, many of which are compatible with older Yamaha and Tohatsu engines, which means that consumables (candles, filters, gaskets) and repair kits are easy to find, even in remote areas, and the engine design is adapted to operating conditions in countries with less quality fuel.
Maintenance regulations for four-stroke engines require the replacement of engine oil after the first 20 hours (break-in) and then every 100 hours or once a season. Two-stroke motors with an auto-mixing system require monitoring the level of oil in the tank and periodic cleaning of the carburetor from resinous deposits if poor-quality fuel is used.
To extend the life of lower unit, it is recommended to regularly check the condition of the ods and the presence of water in the oil. A critical element of maintenance is the replacement of the anodic protection (zinc anode) on the lower unit, especially when used in salt water, and ignoring this element will lead to electrochemical corrosion of the aluminum casing of the gearbox.
Regular replacement of the anode and use of high-quality fuel with an octane number of at least AI-92 are two main factors in the long life of the Parsun engine.
Frequently Asked Questions (FAQ)
Can I refuel the Parsun engines with AI-92 gasoline?
Yes, all Parsun engines, both two-stroke and four-stroke, are designed to work with gasoline with an octane number of at least 92 (according to the research method). The use of AI-95 fuel is allowed, but is not a requirement if the engine does not have an EFI system with high detonation resistance requirements.
How long does the plant guarantee its engines?
The standard warranty period set by the manufacturer is 2 years for individuals, but the warranty conditions may vary depending on the policies of the particular dealer in your area, be sure to keep the warranty card and checks for the passage of the maintenance.
Do I need to dilute gasoline in four-stroke F-series engines?
