How to choose a motor for a specific boat: 5 criteria

Choosing an outboard motor is always a trade-off between power, weight and budget. For NDND motors, the key parameters depend on the type of boat and operating conditions.

  • 📏 Length and type of boatFor PVC boats up to 3 m will be enough 5-6 hp, for aluminum vessels 3.5-4 m need a power reserve (9.9-15 hp).
  • ⚖️ Motor weightIf you plan to carry a boat often, choose models up to 30 kg (PHOTOS)NDNDM-5M or NDND-6C).
  • ⛽ Fuel consumption: Two-stroke NDND motors consume 250-300 g of fuel per 1 hp per hour. NDND-9.9 This is ~2.5 l / h at full load.
  • 🔧 Type of launch: The electric starter is more convenient, but it increases weight and price. Manual start is more reliable in the cold.
  • 💧 Depth of lower unit's immersionFor shallow waters suitable short lower unit (380 mm), for deep water bodies – long (508 mm).

Example of calculation: for a boat Frigate 320 (length 3.2 m, max load 400 kg) is optimal NDND-9.9It will provide speeds of up to 30 km/h with 2 passengers and cargo, without overloading the transom mount. Flying winger-270 (2.7 m) is enough NDNDM-5M.

⚠️ Attention.: 10 hp HP HPD motors require registration with GIMS. Check if you have the rights to operate a small vessel (motor boat category).

Check the power with the boat data sheet (do not exceed the permissible load on the transom)

Check if there is a service center in your area.

Check the warranty (standard 18 months for new engines)

Check the gearbox for oil stains.

Ask the seller to start the engine at idle speed (should work smoothly, without vibrations)->

Top 5 problems of NDNDM motors and how to eliminate them yourself

Even reliable NDNDM motors require repair over time, and most breakdowns involve poor fuel, overheating, or wear and tear, and consider typical faults and ways to fix them without going to the service.

1. The engine does not start or stops on singles

Reasons:

  • 🛢️ The carburetor is clogged (especially after winter storage).
  • 🔥 The spark plug is defective (check the gap - it should be 0.7-0.9 mm).
  • ⛽ Old fuel (gasoline loses its octane number after 3 months)

Solution: Clean the carburetor with compressed air, replace the candle (A17DV or A14DV), drain the old fuel and fill with fresh mixture (gasoline) AI-92 + oil 2T 50:1 ratio.

Engine overheating

Symptoms: motor loses power, steam comes out of the hood.

  • 🌊 The cooling system (algae, sand) is clogged.
  • 🔧 Broken impeller water pump.
  • 🧊 Low oil level in the gearbox.

Solution: Wash the cooling system with clean water under pressure, check the impeller (it should rotate freely), add oil TAD-17I c the reducer to the level of the control hole.

3. Vibration and knocking in the gearbox

This is a sign of wear on bearings or gears.

  1. Remove the gearbox (unscrew 4 bolts on the lower unit).
  2. Check the back shaft (tolerated to 0.5 mm).
  3. Replace oil and oil oil if the oil is blackened or metal shavings are in it.

If the knock is not lost - you will need to replace bearings (set costs 1,500 RUB).

High-speed power drop

Most often it is the worn-out fault piston-set downtrodden exhaust-truckTo verify:

  • 🔍 Remove the cylinder head and examine the piston for bullies.
  • 🎯 Measure the compression (normal for NDND - 8-10 atm).
  • 🔥 Clean the exhaust windows in the cylinder (use a copper brush).

5. Oil leak from the gearbox

The reason is the wear of the gums or the crack in the body. Loctite 577 Replace the omentals for complete repairs. 25×42×7) and check the plane of the gear cap.

⚠️ Attention.If after changing the oil in the gearbox flow did not stop, do not operate the engine - this can lead to jamming of gears and expensive repairs.

  • ⚡ The engine will quickly reach maximum speed (the risk of overheating).
  • ⛽ Fuel consumption will increase by 10-15%.

Modernization of the ignition system

Installation contactless ignition (e.g., the set from BSZ-6>) improves the start in cold weather and stabilizes the work on singles. The cost of the kit is 3,000 RUB, the installation takes 1-2 hours.

3. Carburetor refining

Replacement of chiclers in a carburetor K-60B On more productive (for example, the main chicler with 1.2 mm to 1.3 mm) will add ~0.5-1 hp But this requires fine tuning the fuel / air ratio!

4. Improvement of the cooling system

Installation of an additional thermostat (article) T-107) prevents overheating during long-term operation at high speeds, especially for motors operating in hot climates.

Replacement of the exhaust system

Installation sub-exhaust (Dadewood) reduces noise and improves traction at low speeds, is suitable for quiet fishing, minus - it complicates maintenance.

⚠️ Attention.: Any tuning associated with an increase in power by more than 10% requires registration of changes in the GIMS. Otherwise, the engine may be recognized as uncertified.
What happens if you increase the power of NDND to 15+ hp?

Unauthorized increase in power (for example, cylinder swelling) leads to:

1. Reduction of engine life by 2-3 times (due to increased loads on KSM).

2. Risk of jamming of the piston during overheating.

3. problems with GIMS: during the inspection, the engine can be confiscated, and the owner can be fined 5-10 thousand RUB under Art. 11.8 of the Administrative Code of the Russian Federation ("Violation of the rules for the operation of small craft").

4. Loss of warranty (if the engine is warranty).
