Noise The performance is also higher than that of top Japanese brands, although this is quite standard for two-tackers.
⚠️ Warning: It is not recommended to use pure oil without additives or fuel that has been in the tank for more than 30 days, this can lead to the formation of resins and failure of the carburetor and CPG.
The Secrets of a Long Life of a Motor
To extend the life of the engine, try not to keep it at maximum speeds without load (for example, when towing an empty boat). The optimal operating mode is 80-90% of the maximum power, which ensures better cooling and lubrication of the units.
Fuel consumption and efficiency of operation
Fuel economy is always a big issue, especially when you're away from the base over long distances. Two-stroke engines are traditionally considered more voracious than four-stroke engines, but modern technology minimizes this gap. Properly tuning the carburetor and using quality oil work wonders.
Average fuel consumption for models SharMax At 5-10 hp, it's about 1.5-2.5 liters per hour at full load, and at cruising speeds around 70 percent of the maximum, it drops to 1-1.5 liters, which is comparable to other low-end manufacturers.
An overgrown propeller or damaged blades can increase fuel consumption by 15-20%, putting unnecessary stress on the engine. Regular cleaning and inspection of the propeller is a mandatory procedure.
☑️ Preparation for the season
Instructions for running a new engine
Proper running is the key to long and smooth service of your engine, and many beginners neglect this step, starting the engine immediately at full power, which is a mistake. Laundry process The details of the cylinder-piston group require time and compliance with certain operating modes.
During the first 10 hours of operation, you need to operate the engine in a gentle mode. It is not recommended to open the throttle more than 50-60%. This allows the parts to heat up evenly and take the correct geometric shape without blowing and overheating. The mixture of oil and gasoline should be instructions, usually a ratio of 1:25 for new engines.
breaking in mode:0-2 hours: 30-40% gas (idle and light movement)
2-8 hours: 50% gas (cruising speed)
8-10 hours: 70-80% of gas (short-term acceleration)
After 10 hours: change the oil in the gearbox and switch to the standard mixture 1:50
After the first 10 hours of operation, be sure to replace the oil in the gearbox, it may contain the products of the primary grinding of the gears, it is also recommended to check the tightening of all external bolts, since the vibration during the break-in may weaken the connections, only after that you can move to full operation.
⚠️ Warning: It is strictly forbidden to stop the engine immediately after working at high speeds under load. Let it work for 2-3 minutes on idles to cool evenly and avoid coking the rings.
Quality rolling oil and compliance with the time intervals of operation at different speeds increase the engine life by 30-40%.
Frequent malfunctions and methods of their elimination
Even the most reliable technology sometimes requires the intervention of the owner, and knowing the typical problems allows you to quickly eliminate them on your own without calling the master. SharMax There are a number of specific features, the knowledge of which will facilitate the life of the owner.
The most common problem is with the fuel supply and ignition system, and a idle engine that fails can signal a clogging of the carburetor's jellies or an air sucker. carburettor And the screw mix adjustment often solves the problem of unstable operation.
- 🔥 Overheating: Check the control hole, clean the “water pump” of debris.
- 💨 Power loss: inspect the fuel filter, check the state of the spark plug.
- 🌊 Getting water into the gearbox: Replace the ossels and check the oil for the presence of an emulsion.
- ⚡ No spark: Check the ignition coil and high-voltage wire on the breakdown.
If the engine smokes more than usual, this may indicate a violation of the proportion of the mixture or wear of the piston rings. In the first case, it is enough to adjust the amount of oil, in the second - more serious repair of the CNG will be required. Regular maintenance helps to avoid most of these problems.
What to do if the engine does not start in the cold?
If the engine was long, the gasoline in the carburetor could evaporate, leaving the resins. Try a few times to sharply pull the starter with the closed air valve (suction) to create a vacuum and supply a fresh portion of fuel. If it does not work, remove and blow out the carburetor.
Where to buy original parts and accessories
