Choosing an outboard motor for a small boat is always about finding a compromise between price, reliability and performance. ParsunThe 9.8 horsepower model is one of the most popular in the manufacturer’s lineup, as it formally falls into the category of “up to 10 hp”, which makes it easier to register with GIMS.
But when buying from China, many water-powered vehicles are wary of poor build quality or unpredictable resource, with conflicting opinions ranging from rave praise for value for money to angry reviews of breakdowns in the first season, and to understand the real story, one must look at the experience of hundreds of owners who have already passed the break-in and seasonal fishing phase.
In this article, we have collected and structured data on how to behave. Parsun outboard motor 9.8 We'll look at the technicalities, the typical childhood illnesses, the fuel consumption and maintenance issues that are not covered in the official instructions, and this will help you make an informed decision before you buy.
Technical specifications and design features
Engine. Parsun F9.8BMS (or modifications thereof) is structurally a copy of the time-tested Yamaha 9.9, a two-stroke, two-cylinder unit with a carburetor fuel supply system, with a displacement of 169 cubic centimeters, which provides excellent traction at low revs. The weight of the engine in running order varies between 27-28 kg, making it easy enough to carry by one person, but heavier than many four-stroke counterparts.
An important feature is the CDI ignition system, which does not require adjustment of the candle gap during operation, but is sensitive to the quality of the electrics. The cooling system is forced, water, with a thermostat, which allows the motor to quickly reach the operating temperature. However, owners often note that the quality of the metal used in lower unit and anti-corrosion treatment may be inferior to Japanese standards.
For those who appreciate simplicity of design, the important factor will be the lack of complex electronics. There are no injection control units that could fail from bad gasoline. The mechanical part is as simple as possible: Mikuni carburetor It's this simplicity that often becomes the deciding argument when choosing a remote fishing motor where complex repairs are impossible.
- ⚓ Engine type: two-stroke, 2 cylinders.
- ⚓ Startup system: manual starter (in basic versions).
- ⚓ Control: tiller, with the possibility of setting a distance.
- ⚓ Fuel tank: external, volume of 12 liters (included).
⚠️ Attention: In some batches of recent years of release, there is a plastic lower unit cover that can vibrate stronger than metal. When buying, be sure to check the material of the casing, as this affects the noise level.
Real power and speed indicators
Although the model name features the 9.8, many owners claim that it actually delivers an honest 10 and sometimes more horsepower, especially after running and adjusting the carburetor correctly. On the water, it feels like a confident getting on plane with one adult on board even on heavy PVC boats 3.2-3.5 meters long.
Speed rates are directly dependent on the type of boat and load. On a light inflatable boat with one fisherman, the motor can accelerate the vessel to 25-28 km / h. If you load a PVC boat with two passengers and equipment, the speed will drop to 18-20 km / h, but plane will remain, a critical parameter for those who plan to use the boat not only for trolling, but also for fast crossings.
It is worth noting that maximum-thrust In two-strokes, it's a medium-range engine. Unlike four-strokes, the Parsun 9.8 requires higher rpm to plane effectively. If you like quiet, low-speed, it might seem "nervous" because it tends to stall at minimum rpm without proper idling.
Fuel consumption and efficiency of operation
The appetite of the engine is a concern for every owner. Parsun 9.8 It consumes gasoline in a mixture with oil, which is its inherent feature: the average fuel consumption during active operation on planing is about 3.5-4.5 liters per hour. On economy mode (three thousandth revolution), the consumption can be reduced to 2.5 liters, which makes the engine quite economical for its class.
In order to calculate the budget for the season, it is important to consider not only the cost of gasoline, but also the oil consumption: the ratio of the mixture for running is 1:25, and for permanent use it is 1:50. The use of high-quality synthetic oil for two-stroke engines (TC-W3) is critical. The savings in oil will lead to the formation of soak on the pistons and, ultimately, to cylinder bullies.
Formula for calculating the mixture per 10 liters of gasoline (proportion 1:50):
10,000 ml/50 = 200 ml of oil.
Field surveyors say that a full tank (12 liters) of active upstream or wind travels about 2.5 to 3 hours, enough for a full day of fishing, but it is better not to go on long-distance expeditions without a supply of canisters.
- ⛽ Average flow rate at full gas: 4.0 - 4.5 l / h.
- ⛽ Consumption in trolling mode: 1.5 - 2.0 l / h.
- ⛽ Tank volume: 12 liters (standard).
- ⛽ The recommended octane number is AI-92.
Use only fresh fuel mixture. Gasoline and oil can not be stored for longer than 2-3 weeks, since the oil precipitates and loses its lubricating properties, which is harmful to the crank-shaking mechanism.
Typical Problems and Parsun’s “Childhood Diseases”
Despite its simplicity of design, the 9.8 has a number of specific problems that are worth knowing about in advance: most often owners face poor carburetor assembly, regular jelly flakes can be stuffed with factory shavings, and the level of the float chamber often requires adjustment, which leads to unstable idle work and difficult start "hot".
The second common problem is the quality of the lower unit pipe and cooling system. In the early seasons of operation, there was a detachment of paint inside the lower unit, which could lead to overheating. Also worth paying attention to the glands: regular products sometimes flow after 50 hours, requiring replacement with better quality analogues (for example, from SKF or NOK).
The problem with the lower unit bolt
Many owners have difficulty unscrewing the lower unit bolt after the season, and it often gets stuck. Solution: before you first operate, unscrew the bolt, clean the carvings of the paint, and grease them with graphite lubricant or copper antifriction.
Another nuance is vibration: At high revs, the motor can transmit a tangible vibration to the transom, especially if it is mounted on light PVC boats without a rigid transom, this is solved by installing an additional damper or anti-vibration pad on the rummel, and users complain about the fragility of plastic elements of the lower unit, which can crack when hit by underwater obstacles.
⚠️ Attention: Immediately after purchase, it is recommended to stretch all bolt connections, especially the carburetor, exhaust system and lower unit mounts. Factory puff is often not enough for prolonged operation in vibration conditions.
Service and preparation for the season
And boat-engine Chinese technology forgives mistakes, but loves prevention. The main focus should be on lubrication. Before each season you need to change the oil in the gearbox. The regular oil is often of poor quality, so it is better to replace it with proven brands immediately after purchase.
☑️ Season preparation checklist
Ignition plugs are consumables that require regular inspection. On two-stroke engines, candlelight can tell you the quality of the mixture. Black nagar speaks of a rich mixture (a lot of oil or bad gasoline), white speaks of a poor one (the risk of overheating); The optimal color is brick-brown; a spare candle should always be in the remix.
Preservation for the winter is also mandatory. The engine should be developed on pure gasoline (so that the carburetor does not get clogged with oil resins) or use a fuel stabilizer. lower unit is better stored in an upright position so that the water is completely glass from the cooling system, preventing corrosion from freezing moisture residues.
Comparative table: Parsun 9.8 vs Competitors
For an objective assessment, we will consider how Parsun F9.8BMS It is also a direct competitor in the budget and mid-range segment, with Tohatsu and Hidea competing as the main competitors, which also offer affordable two-strokes.
| Parameter | Parsun 9.8 | Tohatsu 9.8 | Hidea 9.8 |
|---|---|---|---|
| Weight (kg) | 27.0 | 26.5 | 27.5 |
| Expenditure (L/h) | ~4.0 | ~3.8 | ~4.1 |
| Resource (motowatch) | 1000-1500* | 2000+ | 1000-1200* |
| Price (probational) | Low. | High. | Medium |
* Resources are indicative of quality service, and as you can see from the table, Parsun is priced better than Japan's Tohatsu in terms of resource intensity and cost-effectiveness, but the difference in price can offset the purchase of parts for several years to come.
Parsun 9.8 is a choice in favor of budget savings when buying without critical loss of driving performance, but with the condition of more frequent service compared to premium brands.
Summary: Is it worth buying?
In summary, it can be said that Parsun 9.8 It's not a premium product, it's a utility tool, and if you're willing to take the time to set up, pull bolts and change consumables regularly, the motor will serve you for many seasons, and it's perfect for medium-sized fishing, where you don't need record reliability, but you need to have the availability of repairs.
However, if you plan to walk through large reservoirs where a breakdown can be fatal, or if you want a 10-year "got and forget" approach, it's better to consider more expensive options. But in its price niche, the Parsun 9.8 remains one of the top sellers, and the number of satisfied owners far exceeds the number of negative reviews that are often associated with violations of operating rules.
Mainstream The secret to success with this engine - not to expect miracles from it, to use high-quality oil and gasoline, and also to conduct maintenance more often than indicated in the instructions, With this approach, the Chinese unit can surprise with its survivability.
Frequently Asked Questions (FAQ)
Which petrol is better to fill in Parsun 9.8: 92nd or 95th?
The manufacturer recommends AI-92. Using 95th gasoline will not give power gain, since the compression ratio of the engine is not designed for it, and in a two-stroke engine can even lead to a higher temperature combustion mode.
Do I need to disassemble the carburetor immediately after purchase?
It is desirable to remove the top cover and visually inspect the condition of the float chamber for shavings. Often it is enough to blow the channels with compressed air. Complete disassembly and replacement of chicklers is not always required only if problems with the set of turns are noticed.
Can I use Parsun 9.8 for trolling?
Two-stroke engines are good at keeping low speeds after idling properly, but for long-term trolling at speeds below 3 km/h, it is better to use an electric motor or a special trolling mode if implemented, since at a minimum, a two-stroke can hammer candles.
Where to find spare parts if the engine breaks down in the middle of nowhere?
The Parsun 9.8 is structurally unified with the Yamaha 9.9, so many consumables (oils, gaskets, candles, candles, water pump) are suitable from Yamaha. This is a huge plus for repairability in any boating store.
