How to Use and Maintain Your ManualYamaha5BS661 Outboard Motor
If you own a boat and you are looking for a reliable and easy-to-use outboard motor, you might want to consider the ManualYamaha5BS661. This model is a two-stroke engine that has been in production since 1973 and has proven to be durable and efficient. However, like any other machine, it requires proper care and maintenance to keep it running smoothly. In this article, we will show you how to use and maintain your ManualYamaha5BS661 outboard motor.
How to Use Your ManualYamaha5BS661 Outboard Motor
Before you start your engine, make sure you have enough fuel and oil in the tank. The recommended fuel for this model is unleaded gasoline with an octane rating of 87 or higher. The recommended oil is Yamalube 2M or equivalent. The fuel-oil ratio should be 50:1, which means you need to mix 50 parts of fuel with one part of oil. You can use a measuring cup or a funnel to do this. Do not use premixed fuel from other sources, as it may not be compatible with your engine.
Next, check the spark plug and the spark plug cable. The spark plug should be clean and have a gap of 0.6 to 0.7 mm. You can use a feeler gauge or a coin to measure the gap. If the spark plug is dirty or worn out, replace it with a new one. The recommended spark plug for this model is NGK BP6HS. The spark plug cable should be in good condition and securely attached to the spark plug and the ignition coil. If the cable is damaged or loose, replace it or fix it with electrical tape.
Then, check the propeller shaft and the gear oil. The propeller shaft should be free of dirt and corrosion. You can use a wire brush or a cloth to clean it. The gear oil should be changed every 100 hours of operation or once a year, whichever comes first. To change the gear oil, you need to remove the three bolts on the lower unit: the top one is for checking the oil level, the bottom one is for draining the old oil and adding the new one, and the middle one is for venting the air. You can use a wrench or a screwdriver to do this. The recommended gear oil for this model is SAE 90 hypoid gear oil. You need about 250 ml of gear oil to fill the lower unit.
Finally, check the throttle handle and the cable tension. The throttle handle should be smooth and easy to operate. The cable tension should be adjusted so that there is no slack or resistance when moving the handle. You can use a pliers or a wrench to adjust the cable tension.
How to Maintain Your ManualYamaha5BS661 Outboard Motor
To keep your engine in good shape, you need to perform some routine maintenance tasks every time you use it or store it for a long period of time.
After each use, you need to flush the cooling system with fresh water. This will prevent saltwater corrosion and clogging of the water passages. To do this, you need to connect a garden hose to the flushing port on the lower unit and run water through it for about 10 minutes while the engine is idling. You can use a flushing attachment or a muffs device to do this.
Then, you need to drain the fuel from the carburetor and the fuel tank. This will prevent gum formation and deterioration of the fuel system components. To do this, you need to disconnect the fuel hose from the engine and run it until it stops. Then, you need to remove the drain screw on the carburetor and let the remaining fuel flow out into a container. You can use a screwdriver or a coin to do this.
Next, you need to spray fogging oil into the cylinder through the spark plug hole. This will prevent rust and corrosion of the piston and cylinder walls. To do this, you need to remove the spark plug and spray fogging oil into the hole until it comes out from the exhaust port. You can use a spray can or a funnel to do this.
Finally, you need to clean and lubricate the external parts of the engine. This will prevent dirt accumulation and friction damage. To do this, you need to wipe off any dirt or saltwater residue from the engine with a cloth. Then, you need to apply grease or oil to the following parts: propeller shaft splines, shift rod joint, tilt lock lever, steering friction screw, pivot shafts, anode bolts. You can use a grease gun or a spray can to do this.
How to Troubleshoot Your ManualYamaha5BS661 Outboard Motor
Sometimes, you may encounter some problems with your engine that prevent it from starting or running properly. Here are some common issues and how to fix them:
If your engine does not start or runs poorly, check the following: the fuel tank and hose for leaks or blockages, the fuel filter for clogging or dirt, the carburetor for flooding or air leaks, the spark plug for fouling or corrosion, the ignition system for loose connections or faulty components. You can use a spark tester or a multimeter to test the ignition system.
If your engine overheats or loses power, check the following: the cooling system for air bubbles or obstructions, the cylinder head and gasket for cracks or leaks, the piston and rings for wear or damage, the exhaust system for clogging or corrosion. You can use a compression tester or a leak down tester to check the cylinder condition.
If your engine vibrates excessively or makes unusual noises, check the following: the propeller for damage or imbalance, the lower unit for loose bolts or worn gears, the crankshaft and bearings for wear or damage, the flywheel and magneto for cracks or misalignment. You can use a dial indicator or a feeler gauge to check the alignment and clearance.
If you cannot fix the problem yourself, take your engine to an authorized Yamaha dealer or service center for inspection and repair.
How to Store Your ManualYamaha5BS661 Outboard Motor
If you are not going to use your engine for a long period of time (more than a month), you need to prepare it for storage. This will prevent corrosion, deterioration and damage of the engine parts. Here are some steps to follow:
Perform all the maintenance tasks described in the previous section.
Remove the propeller and store it in a dry place. Apply grease to the propeller shaft splines and cover them with a plastic bag.
Drain any water from the engine by tilting it up and down several times.
Remove the spark plug and spray fogging oil into the cylinder through the spark plug hole. Pull the starter rope several times to distribute the oil inside the cylinder. Reinstall the spark plug and tighten it securely.
Disconnect the battery (if equipped) and store it in a cool and dry place. Charge it periodically to prevent sulfation.
Cover the engine with a waterproof cover and store it in an upright position in a well-ventilated area. Avoid direct sunlight, heat sources and moisture.
