outboard motor Wind 8M. It is a legendary domestically produced model that has been in demand for decades among fishermen and small boat owners, and its compactness, reliability and ease of maintenance make it an ideal choice for PVC boats and aluminum shells, but the logical question before buying or transporting such a motor is: how much he weighs How does this parameter affect the operation?
In this article, we will not only give an accurate answer about mass. Wind 8M.But we'll also look at why this is important when choosing a motor, how it relates to power and dimensions, and we'll share practical tips on transportation and storage, and you'll also find comparisons with other popular models and answers to frequent questions from users.
Technical specifications of "Veterok-8M": official data
According to the data-sheet figures of the manufacturer (JSC Motor Sich and its successors), the outboard motor Wind 8M. has the following key parameters:
- 🔹 Power: 8 hp (5.88 kW)
- 🔹 Engine type: two-stroke, carburetor
- 🔹 Cylinder volume: 173 cm
- 🔹 Maximum speed: 5000-5500 rpm
- 🔹 Weight (dry, no fuel and no oil): 26 kg ± 0.5 kg
It is important to clarify that 26kg specified for basic equipment without additional accessories (for example, an external fuel tank or electric start). In real use, the mass can be increased by 1-3 kg due to:
- 🛢️ Fuel in the tank (1 liter of gasoline 0.75 kg)
- 🔧 Oils in gearbox (0.2 l)
- 🔌 Battery (if electrically started)
Why Motor Weight Matters: Impact on Boat and Operation
The weight of an outboard motor is not just a number in your passport, it directly affects:
- Boat stability. Excess of the permissible load on the transom can lead to nose-scraping For PVC boats up to 3.5 m in length, the recommended engine weight is up to 30 kg.
- Maneuverability. The heavy motor complicates control at low speeds and during cornering.
- Transportation. The 26 kg motor can be carried manually, but for long-distance transport (for example, on the roof of the car) you will need fastenings with a margin of safety.
For comparison: engines of similar power (8-9.9 hp) from other brands weigh:
| Motor model | Power (hp) | Weight (kg) | Type of engine |
|---|---|---|---|
| Wind 8M | 8 | 26 | Two-stroke |
| Yamaha 9.9 FMHS | 9,9 | 37 | Four-stroke |
| Tohatsu MFS 9.8 | 9,8 | 35 | Four-stroke |
| Mercury 9.9 M | 9,9 | 38 | Four-stroke |
| Honda BF10 | 10 | 41 | Four-stroke |
As you can see from the table, Wind 8M. It is much lighter than its foreign counterparts, which makes it more mobile, but less comfortable in terms of vibrations and noise (due to the two-stroke design).
The weight of the engine "Veterok-8M" (26 kg) is optimal for PVC boats up to 3.6 m long and aluminum boats up to 3.8 m For larger vessels, it is recommended to consider models from 30 kg, taking into account balancing.
How to properly weigh the motor yourself
If you have any doubts about your data-sheet figures or the engine has undergone modifications (for example, an electric start is installed), its weight can be measured independently.
- 📏 Household changelessness or electronic scales (with a limit of up to 50 kg)
- 🪢 Strong rope or sling
- 🔧 Key to remove the motor from the transom (if installed)
Step by step:
Dump the fuel from the tank (if the engine is not new)
Remove the oil from the gearbox (if necessary, accurate measurements)
Hold the rope by the handle for carrying the motor.
Hang the motor on the bezmen, holding it in a horizontal position.
Please note: if the motor is weighed in assembly with the battery (for models with electric start), add 2-4 kg Also keep in mind that moisture inside the gearbox after use can add up to 0.3-0.5 kg.
⚠️ Attention: Don't weigh the motor by hanging it by the lower unit (vertical part). This can damage the propeller mount or gearbox. Use only the handles designed to carry.
Transportation and Storage: How Weight Affects Logistics
Weight of 26 kg allows you to transport Wind 8M. In the trunk of most cars, but there are nuances:
- 🚗 When folded (with a bent lower unit) the motor takes up little space, but requires reliable fixation to avoid damage to the carburetor or flywheel.
- 🏕️ When transporting on the roof of the car, use soft-hold with shock absorbing gaskets - this will save the paint coating of the engine from chipping.
- ✈️ For air travel, the engine must be packed in a rigid case (the gross weight should not exceed 32 kg in order to avoid additional payments for luggage).
When storing, keep in mind that:
- 🔴 Long vertical position (e.g. on a wall) can lead to gear-leak.
- 🔵 The best option is a horizontal position on wooden bars or a special stand.
Before long-term storage (more than 3 months), drain the fuel from the carburetor and add 5-10 ml of engine oil to the cylinder, turning the crankshaft manually.
Comparison with other models of the series "Winds"
The plant "Motor Sich" produced several modifications of engines "The Wind"And their weights varied depending on their power and design, and here's a comparison table.
| Model | Power (hp) | Weight (kg) | Features |
|---|---|---|---|
| Wind 8 | 8 | 27 | An outdated model without an upgraded gearbox |
| Wind 8M | 8 | 26 | Lightweight version with improved corrosion resistance |
| Wind 12. | 12 | 32 | Increased engine capacity (245 cm3) |
| Wind E8 | 8 | 28 | Modification with electric start (+ battery) |
As you can see, Wind 8M. It is the lightest model in the lineup, making it popular with tourists and fishermen who care about mobility. "Breeze 12" despite the greater weight - it will provide better traction and stability on the wave.
Frequent errors in working with the engine and their consequences
Improper exploitation Wind 8M. It can cause not only damage, but also weight gain through moisture accumulation or corrosion.
- Wet storage. The condensation inside the gearbox adds weight and accelerates wear and tear of the gears. Solution: Use silica gel moisture absorbers.
- Use of poor quality oil. Cheap oils don't burn completely, so they're soaked on the piston and they increase the engine mass.
TC-W3(for example, Lukoil 2T Marine). - Overloading the boat. If the weight of the motor + passengers + cargo exceeds the permissible for the boat, this leads to the loss of the vehicle. engine-heating and increased fuel consumption.
⚠️ Attention: If the engine became "heavier" by 1-2 kg after winter for no apparent reason, this may indicate a accumulation of water in the silencer or gearbox.
What if the motor is vibrating more than usual?
Increased vibration is often associated with an imbalance of the propeller (for example, after hitting an obstacle) or wear of the lower unit bearings.
1. Examine the propeller blades for deformations.
2. Check the backlash shaft in the gearbox (permissible backlash - no more than 0.5 mm).
If necessary, balance the screw in the service center or replace it (the original screw for the Wind-8M weighs ≈ 1.2 kg).
FAQ: Answers to popular questions
Can I install the Wind 8M on a boat 4 meters long?
Yes, but with reservations, for a boat of 4 m, a 9.9-15 hp engine is recommended. Wind 8M. It's fine if:
- 👍 The boat has a reinforced transom (thickness of at least 20 mm for aluminum).
- 👍 The maximum load does not exceed 3 people + a load of 100 kg.
- 👍 You do not plan to reach speeds of more than 30 km / h (optimum mode for 8 hp).
Otherwise, the engine will work at the limit of its capabilities, which will reduce its resource.
What weight does the original propeller for the “Wind-8M” have?
A standard three-blade aluminum alloy screw weighs 1.2 kgSteel screws (e.g. from Solas) may weigh up to 1.8 kg, which will increase the total engine mass and affect its balancing.
How much does the Wind 8M weigh with a fuel tank?
The weight depends on the volume of the tank:
- 🛢️ Built-in tank (2.5 l) + fuel: +2 kg.
- 🛢️ Removable tank (12 l) + fuel (full): +9 kg.
- 🛢️ Removable tank (24 l) + fuel (full): +18 kg.
Keep in mind that the weight is not evenly distributed: the tank is usually attached closer to the bow of the boat, which can affect the different.
Can the weight of the motor be reduced to facilitate transportation?
Yes, but with limitations:
- ✅ Replace the metal screw with a composite screw (savings up to 0.5 kg).
- ✅ Remove the muffler (if local regulations allow - saving 0.8 kg).
- ❌ It is not recommended to remove the protective casing of the flywheel - this violates the cooling of the engine.
The best way to do this is to use cock-bag for carrying.
How does the weight of the engine affect registration in GIMS?
In Russia, engines up to 10.88 hp (8 kW) not registered However, if the total weight of the boat with the engine and load exceeds 200 kg, it may be necessary to boat-certificate (for small vessels).
