Outboard Motors HDX In the last 5 years, they have become firmly in the top 10 most talked about brands in the Russian small shipbuilding market, distinguished by a combination of affordable prices, locally adapted technical solutions and a wide dealer network. HDX It is so popular among fishermen and owners of PVC boats, despite fierce competition from the world. Yamaha, Mercury and Tohatsu?

In this article, we will discuss HDX production historyWe will analyze the entire model range (from compact models). 2.5 hp powerful 30 hp), compare them with direct competitors and give practical recommendations for the choice. HDX technology that other Chinese manufacturers don’t have - for example, the system EFI In budget models or patented corrosion protection.

Who makes HDX engines: brand history and factories

Controlling interest in the company HDX Marine owned by a Chinese holding company Zhejiang Huadong Power Machinery Co., Ltd.It's a small-sized engine that has been specializing in the production of small-sized engines since 2008. HDX They are assembled in two factories:

  • 🏭 Main production Wenzhou, Zhejiang Province, China, produces 80% of the model range, including the flagship series. HDX F30 and HDX T20.
  • 🌍 Assembly shop in Russia — Naberezhnye Chelny (Tatarstan) Since 2022, the production of engines with a capacity of up to 15 hpThis has reduced logistics costs by 25%.
  • 🔧 R&D center They're developing electronic control systems and testing prototypes for the European market.

Interesting fact: despite the Chinese origin, HDX It is a "Euro-Asian brand" and all engines are certified to the standards. CE and EPASince 2021, the company has been allowed to supply to the EU countries under its own name (previously exported as OEM products for other brands).

⚠️ Attention: There are fake brand names on the market HDXOriginal engines always have a serial number engraved on the gearbox body and a holographic sticker on the lid of the gas tank.

Model range HDX: technical specifications and purpose

Motor lineup HDX span 2.5 before 30 hpAnd each series has a very specific specialization, like models. HDX T from T2.5 before T15) optimized for PVC boats and lightweight design, and series HDX F (F20, F25, F30) is designed for aluminium and composite shells.

Model Power (hp) Engine capacity (cm3) Type of launch Weight (kg) Features
HDX T2.5 2.5 52 manually 12.8 The lightest in the line, ideal for inflatable boats up to 2.5 m
HDX T9.9 9.9 211 Manual/Electro 38.5 First model with a system Oil Alert (Automatic shutdown at low oil level)
HDX F20 EFI 20 327 Electro 52 The only one in the class up to 20 hp with electronic fuel injection (EFI)
HDX F30 30 498 Electro 78 Flagship model with four-stroke engine and system VCT (variable gas distribution phases)

The model deserves special attention. HDX T9.9 EFI It is the world’s first powered motor. 9.9 hp with electronic fuel injection, which is cheaper than analogues from Yamaha It's 30 to 40 percent fuel consumption, but it's only a fraction of the fuel consumption. 2.1 l/h at maximum speed (against) 2.8-3.2 l/h from carburetor competitors.

Comparison of HDX with competitors: Yamaha, Mercury, Tohatsu

Main advantage HDX In front of Japanese and American brands, price/quality ratioLike a motor. HDX F20 EFI It costs about 180 000 rubles, while a similar model Yamaha F20 It's going to cost 280,000+ rubles. But where's the catch?

  • 🔧 Reliability: According to the service centers, the resource HDX before major repairs is ~2,500 motor hours (versus ~4,000 y) YamahaHowever, with proper maintenance (oil change each time) 50 hours., washing with salt water ) this figure increases to 3 000 +.
  • ⚡ Fuel economy: Models with EFI (for example, HDX F20 EFI) consume 15-20% less fuel than carburetor analogues from Mercury.
  • 🛠️ Repairability: Spare parts for HDX cheaper by 40-60%, but their range is inferior TohatsuFor example, a piston group for HDX T9.9 You can find it in 5 separate sets, and Tohatsu M9.9 - at 12.
  • 📦 Package: In basic delivery HDX There is a full set of tools for maintenance (keys, screwdrivers, oil), while Mercury This is an option for +5,000 rubles.

Critical moment: motors HDX It is not recommended to use salt water for more than 3 consecutive seasons. And they don't completely flush the cooling system. Yamaha and Honda have stainless steel protection on all critical nodes.

Why is HDX 30-50% cheaper than Yamaha?

1. Localization of production in China and Russia reduces logistics costs.

2. Use of unified parts (for example, one carburetor is suitable for models 5-15 hp).

3. no dealer markup – HDX sells motors directly through its own network of service centers.

4. Savings on marketing: The brand does not sponsor global regattas, unlike Mercury or Suzuki.

Pros and cons of HDX outboard motors

To assess objectively HDXWe surveyed 50 owners (data for 2023) and analyzed reviews on the sites. Fishki.net, Drive2 and Yandex. Market.Here's what happened:

Advantages

  • 💰 Price: On average, 30% cheaper than Japanese counterparts with comparable specifications.
  • 🛢️ Economics: Models with EFI fuel consumption at the level Hondabut stand as if Parsun.
  • 🔧 Ease of maintenance: Replacement of oil takes 10 minutes (versus 20-25 y) Mercury because of the complex design of the pallet.
  • 📦 Package: The box contains everything you need for installation, including adapters for different transom devices.

Deficiencies

  • 🔊 Noise: Noise level at idle speeds ~68 dB (y) Yamaha - 62 dB.
  • 🛠️ Assemblance quality: In the first batches (until 2020) there were backlashes in the tiller, but now the problem has been solved.
  • 🌡️ Overheating: At air temperatures above 35°C, forced cooling is required (e.g., submerging the motor in water for 5 minutes every 2 hours of operation).
  • 📉 Power drop: After 1,000 hours, some owners note a decrease in maximum speeds by 5-7%.
⚠️ Attention: Motors. HDX series T before 15 hp) are not designed for long-term operation at maximum speeds. If you operate for more than 30 minutes at full power, the risk of overheating increases by 3 times.

1. 1 hour at idle speeds (no more than 1,500 rpm).

2. 2 hours at 50% power (3,000 rpm).

3. 1 hour at 75% power (4,500 rpm).

This will increase the engine life by 20-25%.
