Often boat owners are faced with the fact that the engine "troubles" or loses power at high speeds, this can be a sign of pollution of the fuel system or problems with the air supply. defectionChecking every cog and gasket.
It is important to understand that ignoring the first symptoms of a breakdown can lead to major repairs, for example, getting water into the cylinders through a damaged oment can cause hydraulic shock, which is fatal to the engine.
⚠️ Warning: If you notice white smoke from the exhaust pipe or an emulsion on the oil probe, immediately stop operating the engine and take it to the workshop.
We use modern verification methods. circuitryIt's a way to find cliffs or short circuits, even in complex wire harnesses, and it's a way to make sure that you can get a quick, inexpensive repair.
Repair of carburetor and injection systems
The fuel system is the circulatory system of your outboard motor, and depending on the year of manufacture and model, it can be carburetor or injector, and in the workshop at Gusar, we take all the options back to you, ensuring perfect mixing.
For carburetors Clean internal channels and proper adjustment of the float chamber are critical, and we perform ultrasonic cleaning, replace worn membranes and needles, and synchronize multiple carburetors on multi-cylinder engines.
- 🔧 Complete disassembly and defective fuel units.
- ⚙️ Setting up the idling and the quality of the mixture under load.
- 🛢️ Replacement of fuel hoses and fine cleaning filter.
- 💨 Checking the tightness of the intake manifold.
Injection systems require a computer connection to analyze the sensors. nozzleCheck the pressure in the fuel ramp and update the software of the control unit if necessary.
Why does the engine stop on idle?
A common cause is air suction through the intake manifold or idle duct contamination, and it's also possible that the needle in the carburetor will stick because of old fuel.
The quality of the fuel used directly affects the life of the engine, and we recommend installing additional fuel filters-sludges to protect expensive equipment from dirt and water.
Recovery of the lower unit Part and Reductor
The bottom of the motor, or lower unit, takes the main loads from water, obstacles and corrosion, and repairing the gearbox is one of the most difficult and demanding tasks that the workshop at Gusar performs.
The main problem that owners face is getting water into the gearbox oil, and you can see that by changing the color of the lubricant to milk oil, if you don't change it in time. plumbing And seals, water will cause corrosion of gears and bearings, which will lead to expensive repairs.
We pressurize the gearbox to detect microcracks in the body, and if the geometry of the body is broken, we offer options for repairing or replacing the gearbox, and we also deal with changing gears and eliminating backlashes.
| Type of malfunction | Symptoms | Method of decision |
|---|---|---|
| Wear of the gums | Oil in water, emulsion | Replacement of osteoils, check of shafts |
| Damage to the gears. | Noise, vibration, no movement | Defective, replacement of a pair of gears |
| Switching problems | Hits the gear, tight move. | Adjustment of the cable, replacement of the backstage |
| Corrosion of the shell | Leaks, visible damage | Welding, replacement of gearbox body |
After repair, we necessarily run on the stand or water to make sure that there are no leaks and extraneous noises. Guarantee for tightness of the gearbox is 12 monthsThis confirms our confidence in the quality of our work.
Change the oil in the gearbox every 50-100 hours or at the beginning and end of the season, a cheap way to control the condition of the seals and prevent corrosion from the inside.
Maintenance of the cooling system and prevention of overheating
The water cooling system is what keeps the engine temperature within safe limits, and overheating is one of the main causes of jamming of the pistons and deformation of the cylinder heads.
In the workshop at Gusar, we pay special attention to the state of impeller The rubber impeller will tan, crack, and stop pumping water over time, and we recommend changing it preventively without waiting for it to fail completely.
Often the cause of overheating is the water channels in the cylinder block that are overgrown with salt or silt, and we chemically and mechanically clean the cooling system, restoring normal fluid circulation.
- 🌊 Replacement of water pump impeller and sealing sleeve.
- 🧼 Washing the thermostat and checking the valve.
- 🔍 Cleaning the control hole (urinal).
- 🌡️ Replacement of temperature sensors and overheating alarms.
If the motor is running in salt water, the risk of corrosion increases many times over, and we treat the internal cavities with special corrosion-resistant compounds, prolonging the life of the engine.
⚠️ Warning: Never start the engine without water or on dry, even for a few seconds, guaranteed to disable the pump oal and may damage the impeller itself.
