Choosing a power plant for a PVC boat or a small boat is always a compromise between power, weight and budget. In the segment of Chinese outboard motors, which confidently pushed out the eminent Japanese brands, the model is the model of the model. Hidea HD50FWS This 50 horsepower two-stroke engine is often seen as a more affordable alternative to classics like Tohatsu or Yamaha, but with a modern design and enhanced functionality.
Water engineers value this model for its versatility: it feels great in both planing under full load and trolling. Chinese engineers did not reinvent the wheel, but instead took the time-tested Yamaha 50HP design as a basis, making a number of design improvements. Heidi 50 outboard motor It became a hit among fishermen and lovers of active recreation on the water.
In this article, we will discuss the technical details, operating features and real fuel consumption so that you can make an informed decision. It is important to understand that proper care and competent running can extend the life of the engine for many years, turning a budget purchase into a reliable assistant.
Technical specifications and design features
At the heart of the model is a two-stroke forced water-cooled internal combustion engine, with a cylinder capacity of 796 cubic centimeters, which ensures excellent low-speed traction, the gas distribution system is built on the classic loop purging scheme, but the HD50FWS uses the O. E. S exhaust gas cleaning system, which makes the engine more environmentally friendly and reduces smoke.
The Capacitor Discharge Ignition (CDI) system is particularly noteworthy for providing a stable spark even when operating at low speeds, which is critical for fishing. In addition, the electronic speed limiter protects the piston group from overheating and destruction in the event of extreme loads. The motor is structurally divided into three main parts: lower unit, lower unit leg and the power unit itself, which facilitates transportation.
An important element is the lower unit leg, which in this model has a standard length of 386 mm (S). This is the optimal size for most inflatable boats and small aluminum boats. The gearshift system is implemented through a rumble or remote box controller, ensuring a smooth transition between the Forward, Neutral and Back modes.
When buying, be sure to check the equipment: some dealers can sell the engine without a remote tank or control box, which come in the basic version.
Below is a table with the main technical parameters that will help compare Hidea with competitors:
| Parameter | Meaning |
|---|---|
| Type of engine | two-stroke, 2-cylinder |
| Workload | 796 cm |
| Maximum power | 50 hp (36.8 kW) |
| Ignition system | CDI with speed limiter |
| Weight (without oil and fuel) | 84.5 kg |
Fuel consumption and efficiency of operation
One of the most common questions that arises from potential buyers is how much does this beast eat? Two-stroke engines are traditionally considered more voracious than four-stroke counterparts, but modern carburetion technologies allow you to optimize the combustion process of the mixture. The real cost depends on the style of control, the state of the propeller and the loading of the boat.
In the trolling mode, when the turnovers are minimal, Heidi 50 outboard motor It consumes about 1.5-2 liters of fuel mixture per hour, which is an ideal fishing regime, allowing you to spend the whole day on the water on one tank. When you get on plane, the flow increases sharply and can reach 20-22 liters per hour, but in cruising mode (about 4000-4500 rpm), you can keep the figure at 12-15 liters.
To achieve maximum efficiency, it is important to choose the right screw. A standard three-bladed aluminum screw with a diameter of 11.5 inches and a step of 13 inches is a compromise solution. If you often swim with a full load, it makes sense to consider a screw with a smaller pitch so that the engine does not work in “suffocation” mode.
Keep in mind that fuel savings are not just about money, but also about engine life. Working on a re-enriched mixture leads to the formation of soak on candles and in a muffler, which over time reduces power, and regular cleaning of the carburetor and the use of high-quality gasoline AI-92 or AI-95 will help to avoid these problems.
The procedure of breaking in: step-by-step instructions
Running is a critical step, and 80 percent of the success of the operation depends on it, and many owners make the mistake of giving full gas immediately, leading to bullying of the piston group. Hidea HD50FWS It requires careful attention in the first 10 hours of operation, while the parts are rubbed together.
The process of running in is divided into several stages: the first 2 hours (10 tanks) the engine must run at idle speed or at minimum thrust (about 1/10 of gas). At this time, the piston rings initially fit against the walls of the cylinders. The next 4 hours (another 10 tanks) you can increase the load to 1/2 gas, periodically changing the speed, but not raising them above 3000 rpm.
☑️ Checklist of proper breaking in
At the stage of 6 to 10 hours of operation, a short-term opening of the throttle valve up to 3/4 (about 4500 rpm) is allowed, this is necessary for training the rings in conditions of higher temperatures and pressures. Full operation at maximum speeds is allowed only after the 10th tank of the fuel mixture is developed.
⚠️ Warning: Do not keep the humming device in one position for long periods of time during break-in, constantly change the inclination angle of the lower unit and the rpm to ensure uniform lubrication of all nodes.
After the procedure of running in, be sure to replace the oil in the gearbox. During the grinding of the gears, metal shavings can get into the oil, the presence of which on the cork magnet is normal, but you can not leave it in the system.
Carburetor setup and maintenance
Carburetors installed on boat-enginesThe main parameters that can be adjusted are the quality of the mixture at idle speed and maximum revs. The factory setting is usually optimal for sea or large reservoir conditions, but in mountain rivers or hot climates, correction may be necessary.
Adjustment is done by a Low Speed screw and a High Speed screw, turning the screw clockwise makes the mixture poorer, counterclockwise makes it richer, if the motor stalls when the gas is opened abruptly or on idles, the mixture is probably too poor, black smoke from the exhaust and smoked candles indicate over-enrichment.
The Secret to Stable Work
Many experienced motorists recommend before winter storage completely drain the fuel from the float chamber of the carburetor, as modern gasoline with ethanol additives can stratify and clog the jellyfish for several months of downtime.
Maintenance also includes lubricating the rotating points of the rummel and the gearshift mechanism. Use a water-resistant lithium lubricant. Check the thermostat regularly: if the motor does not reach operating temperature, the thermostat may be jammed in the open position, leading to increased fuel consumption.
Typical malfunctions and methods of their elimination
Like any technique, Hidea 50 They may have some problems in operation, and most often, owners complain of difficulty starting or idling, and 90 percent of the time, it's the ignition or fuel system, not the mechanical breakdown of the engine.
If the engine doesn't start, the first thing you do is check for a spark. Twisted the candle, press it with your skirt against the engine mass, and pull the starter. The spark should be bright blue and punch the gap confidently. If the spark is red or weak, check the ignition coil and high-voltage wires. It could also be a contaminated fuel filter-sulphant.
- 🔥 Motor warms: Check the control trickle of water. If it's not there, maybe the water intake grille is clogged or the impeller pump is worn out.
- 💨 The engine smokes: Check the ratio of oil to gasoline mixing. The excess oil leads to candles and silencers coking.
- 🔊 Extraneous noise: May indicate wear of the dayshaft bearings or the entry of a foreign object into the screw.
Another common problem is cutting the screw veneers, which happens when you hit underwater obstacles. Always have a set of veneers and a key to replace them. Using non-original soft metal veneers can cause them to be cut off frequently even on small obstacles.
Timely replacement of the impeller pump (every 2 seasons) is the cheapest way to avoid engine overheating and expensive repair of the piston group.
Comparison with competitors and final conclusions
In the market of 50 horsepower engines Hidea HD50FWS There are serious competitors like the Tohatsu M50D2, Yamaha 50CEH and their numerous Chinese clones (Parsun, Sea-Pro). Heidi's main advantage is the balance of price and build quality. The motors are assembled in factories that also produce parts for Japanese brands, which ensures compliance with standards.
Unlike some budget counterparts, Heidi comes with better lower unit materials and improved corrosion protection. Anodized coatings and the use of stainless steel in key units allow the engine to operate in salt water without the rapid appearance of rust, which is often the Achilles heel of cheap "Chinese".
⚠️ Warning: When operating in seawater, be sure to use a motor with only zinc anodes installed, and their absence will lead to electrochemical corrosion of the aluminum body in one season.
In summary, it can be said that Hidea 50 hp. It is a great choice for those looking for a reliable workhorse without overpaying for the brand, and provided that it is properly run and regularly maintained, it can run thousands of hours of motorcycling, ensuring comfortable and safe movement on water.
What is the proportion of mixing oil for running and normal work?
For the break-in period (the first 10 hours), a ratio of 1:25 (40 ml of oil per 1 liter of gasoline) is recommended. After break-in, you can switch to a standard ratio of 1:50 (20 ml per 1 liter), using high-quality semi-synthetic oils for two-stroke outboard motors labeled TC-W3.
Can I use this hydraulic motor?
Yes, the HD50FWS model is compatible with most standard hydraulic lifts for motors up to 60 hp However, due to the features of the lower unit mounting, it may be necessary to select specific transition plates or use a universal mounting kit.
Which screw is better to put for an inflatable boat 3.8-4.2 meters?
For inflatable boats of this size with 2-3 passengers, a three-blade propeller with 11-12 inches increments is optimal, which will provide a quick exit to plane without undue load on the boat transom and engine.
