In the last decade, the market of low-power outboard motors has experienced a real revolution: Chinese brands have ceased to be synonymous with “cheap consumer goods”, and some models have overtaken even Japanese giants in terms of reliability. HDX F 5 BMS A striking example of such a breakthrough: a four-stroke engine with power 5 hpIt is positioned as a “middle ground” between budget two-stroke engines and premium engines. Yamaha or HondaBut is he that good in practice?
This article is not just a retelling of the specifications from the manual. 3 last yearsCompared to the engine with direct competitorsParsun F5BMS, Hidea HD5FS) and also identified 5 Hidden ProblemsThe PVC boats are not sold out, if you're going to have a PVC boat. 3.6 m or an aluminum "cutter" to 4mThis review will help avoid costly mistakes.
Spoiler: HDX F 5 BMS It really does justify its price, but only if it is respected. three key conditions (Operation) Now, to the details.
Specifications of HDX F 5 BMS: what is hidden behind the numbers
On paper, the engine looks flawless: a four-stroke engine with a OHC distributionelectronic ignition CDI, fuel tank on 12 l l and claimed expense 1.3 l/hour But let's see what that means in practice.
First of all, working volume 139 cm This is the standard for 5-horsepower engines, but HDX stand out fermented According to service centers, when properly maintained, the engine can withstand 2,000 motor-hours without major repairs, this is 30%than class analogues Parsun or Sea-Pro.
Secondly, lubrication here split (oil is poured into the crankcase, not mixed with gasoline), which reduces the wear of parts. 10 hours. oil consumption can reach 100 ml/h It’s normal, but many owners get scared thinking that the engine is eating oil.
And finally, 26kg On the one hand, the engine is lighter than its Japanese counterparts (e.g., the Japanese engine). Honda BF5 weight 29 kgIt is also more than two-stroke competitors (the same ones). Mercury 5M — 22 kgFor transportation on the roof of the car, the difference is critical: with weight from 25 kg The mountings must be checked every time 500 km.
- 🔧 Type of enginefour-stroke, single-cylinder, air-cooled
- ⚡ Maximum power: 5 hp at 5,500 rpm
- ⛽ Fuel.AI-92 (AI-95 with additives is prohibited!)
- 🛢️ Volume of oil: 0.6 liters (SAE 10W-30 or 10W-40)
- 🔄 Transfer ratio: 2.08:1 (optimally for propellers 7–9 inches)
⚠️ Attention: The instructions indicate that the engine can be refueled AI-95, but in practice this leads to the use of the engine. formation of soak on candles after 50 motor hoursThe reason is the low octane number in Russia's 95th gasoline. Use only the AI-92 from the gas stations tested.
Comparison with competitors: why HDX wins over Parsun, but loses to Honda
To understand the real value HDX F 5 BMSCompare it with the three main competitors in the segment of four-stroke engines up to 5 hp:
| Parameter | HDX F 5 BMS | Parsun F5BMS | Hidea HD5FS | Honda BF5D |
|---|---|---|---|---|
| Price, thousand rubles. | 85–95 | 80–90 | 75–85 | 140–160 |
| Resource to capital, motor watches | 1800–2000 | 1200–1500 | 1000–1200 | 3000+ |
| Fuel consumption, l/hour | 1.2–1.5 | 1.4–1.7 | 1.5–1.8 | 1.0–1.2 |
| Noise level, dB | 78–82 | 80–85 | 83–87 | 72–76 |
| Guarantee, years. | 2 | 1 | 1 | 3 |
As you can see from the table, HDX It is an intermediate position: it cheaper than Honda 40%but More reliable than Parsun/Hidea by 30-50%The main advantage is that price-to-resource balanceBut there are also weaknesses.
- 🔊 Noise: At maximum speeds, the engine runs louder than its Japanese counterparts (a difference of ~5 dB), which is critical for fishing in "quiet" water bodies.
- ⚙️ break-inThe first 10 hours require strict compliance with the regime (no more than 3/4 of the gas), otherwise the piston “burns” to 500 hours.
- 🛠️ ServiceParts are cheaper than the ones Hondabut their supply is up to 3 weeks (production in China).
Interesting fact: according to the forum "Boat-Motor" (2023), 68% of HDX F 5 BMS owners switch to this engine from two-stroke analogues (Mercury 5M, Tohatsu M5B) because of the fuel economy (difference in expenditure up to 40%).
Running and first runs: mistakes that kill the engine in 1 season
Most breakdowns HDX F 5 BMS first-time 50 hours of motorsport The manufacturer specifies standard recommendations (do not exceed 3/4 gas, avoid long work on singles), but there are 4 Critical NuancesWhich is not written in the manual:
1. Temperature conditionsThe engine needs to warm up. at least 5 minutes before the movement, but not on singles. 1/3 gas If you give the gas right away, the piston rings will get stuck because of the lack of lubrication.
2. First oil changeThe instructions say change the oil after 20 hours.But in practice it is better to do it afterward. 10 hours. - in this case, metal shavings from the finishing of parts will not have time to damage the bearings.
3. Fuel mixtureEven if the engine is four-stroke, the first ones are 3 refueling add-on Liqui Moly Motor Protect (20 ml per 10 liters of gasoline) - this will accelerate the piston burn.
4. The propellerThe plant is rotating. 7.5×7 inchesbut for boats of weight more than 200 kg put it right away 8×9 - it'll reduce the load on the gearbox.
Warming up by 1/3 of gas 5 minutes | First 2 hours - no more than 1/2 gas | Oil level control every 2 hours | Oil change after 10 motor hours | Use of additive in the first 3 refueling->
⚠️ Attention: If after running the engine began to "trot" at idle speeds, check candlelight (should be) 0.7-0.8 mmIn 80% of cases, the problem is solved by replacing the candle with a candle. NGK BPR6ES (Article 2240).
Tuning and Upgrade: What Can Be Improved in the HDX F 5 BMS
The standard configuration of the engine is quite sufficient for most tasks, but there are 3 directions of tuningThese are the ones that really improve comfort and reliability:
1. Cooling systemInstallation. water-pump (for example, Sierra 18-3335>) increases the engine life 20–25% when operating in hot climates (temperature above +30 ° C). 3 thousand rubles.But it pays off in a season.
2. SilencerThe standard muffler wheezes at high revs. tin (for example, Mercury 35-8M0033091> reduces noise 3-5 dB without loss of power.
3. ElectronicsInstallation. tachometer (for example, Lowrance TM-5> allows you to control the speeds more accurately, which is critical when running. key-breaker This protects against accidental launch by children.
A separate question. propellerTo increase speed on light boats (up to the 150 kg) fits the screw 7×8 (8 inches) and for heavy aluminum boats, 8×10But remember, the pitch of the screw is changed to ±1 inch shifts 200-300 rpm.
How to check if the screw is suitable for the engine?
Take the tachometer readings at full gas if the rpm goes beyond the limits. 5200-5,700 rpmThe screw is wrongly selected:
- Too high a turn. (more than 5700) - increase the pitch of the screw.
- Too low. (less than 5200) – reduce the pitch.
The optimal range for the HDX F 5 BMS is 5400-5600 rpm.
Typical malfunctions and ways to eliminate them
Even with proper operation HDX F 5 BMS has 5 Diseases That Appear After 100-300 Motorcycle HoursLet's look at their causes and solutions:
- 🔥 Overheating at idle speeds
Cause: Clogging of water channels in the gearbox cover.
Solution: Pressurized water jet washing (use a pressure wash nozzle) If it doesn't work, replace it. impeller (article)
HDX-0035, the price is ~ 800 rubles. - 🛑 Self-sustaining at high speeds
Cause: Hall sensor malfunction or fuel filter clogging.
Solution: Cleaning the filter (located under the fuel hose) or replacing the sensor (article)
HDX-0042, ~1200 rubles. - ⚡ A faint spark.
Reason: Wear of the candle or breakdown of high-voltage wire.
Solution: Replacement of candles with NGK BPR6ES Testing the wire by the tester (resistance must be 5-7 kom).
The most expensive breakdown. crankshaft bearing wear (Made by a metal knock when warmed up) In this case, the repair will cost in the future. RUB 8,000-12,000.So it’s best to prevent the problem: change the oil every time. 50 hours of motorsport (Not 100 as the manufacturer recommends).
1. Remove the candle and pour into the cylinder 5 ml of oil 10W-40.
2. Scroll the starter without a candle (to lubricate the piston).
3. Set a new candle and try to start.
This method saves from the "laying" of the rings after a long downtime.
