OEM Yamaha Outboard Parts FAQs

How can I best maintain the health of my Yamaha Outboard lower unit?

To make sure your Yamaha outboard motor keeps running smoothly and lasts longer, it's important to swap out the gear lube regularly. Having the right supplies (like Yamalube gear lube) close at hand will make this crucial maintenance job a breeze.

Here are five great advantages of using a Yamaha marine gear lube kit to keep your Yamaha outboard motor in prime condition in the long run.

1. Your Yamaha outboard motor will start facing deterioration from the moment it is launched into the water, especially if it is utilized a lot, is left to corrode and isn't properly stored or kept up.
2. If you have a Yamaha outboard, you can save a lot of money and time by doing the repairs yourself. It won't take long; in just a few hours you could change the oil, replace common parts and lubricate the engine. Doing it yourself is a lot cheaper than having a marine mechanic do it for you.
3. To keep your Yamaha outboard motor in good shape, you need to use the proper lubrication. Yamahaonlineparts.com sells Yamaha marine gear lube kits, so you can rest assured that your engine has the highest quality oil.
4. To ensure your Yamaha outboard motor runs smoothly and prevent any unexpected issues, regular maintenance is key. For brand-new motors, you should service them after 20 hours of use and then every 100 hours afterward.
5. Yamahaonlineparts.com's Yamaha marine gear lube kits make it easy for you to complete gear lube changes and make sure you're not making the wrong purchase or settling for low quality. Every kit has Yamalube gear lube, a Yamaha gear lube pump, and the perfect Yamaha outboard lower unit drain gaskets for the job.

How do I know if my Yamaha outboard head gasket needs to be repaired?

Overuse and exposure to high temperatures, saltwater and other elements can cause Yamaha outboard head gaskets to break down and lose their effectiveness. If a head gasket isn't swapped out at the first sign of deterioration, water can enter the engine, causing performance to suffer and possibly leading to severe engine damage. So, be sure to keep an eye on your outboard's head gaskets and replace them if needed to protect your engine.

To avoid this, there are several telltale signs to look out for when it’s time to replace your Yamaha outboard head gasket:

1. Reaching the 4-Year Mark
2. Low Pressure in the Cylinders
3. Water Coming Out of a Spark Plug Hole
4. Black Specks, Crud, and Slime in the Cylinder
5. Idle Runs Too Slow or Rough
6. Holes In the Head Gasket

Is winterizing my Yamaha outboard important?

Taking out your boat can be a blast, but if you want to make sure your Yamaha outboard engine is ready to go when the new season starts, you should winterize it the right way. To make sure your Yamaha outboard lower unit is properly winterized, there are a few essential steps you need to take.

1. If you navigate a saltwater vessel, it's essential to flush your engine to clear away any accumulated salt. Not attending to this issue can generate corrosion within the motor. Salt crystals in the lower unit can be highly destructive for those who take to the seas. Freshwater boaters should also flush their motor from any residual mud and dirt to avoid harm.
2. Maintaining your fuel system is essential. If your boat won't be in use for more than two to three months, be sure to use a fuel stabilizer like Yamaha Fuel Stabilizer or Conditioner Plus. The package will specify the right amount to add to your fuel. For example, if the engine is going to be stored for more than two months, add 1 ounce of Yamaha Fuel Stabilizer and Conditioner Plus per gallon of gasoline.
3. Use a fogging oil, like Yamalube fogging oil– a wax-based oil that coats the engine and helps to prevent corrosion.
4. Before putting your Yamaha outboard engine away for storage, it is highly advised to replace the oil in the lower unit to guarantee that there is no water present. If not, the liquid may solidify and widen, potentially causing damage to the lower unit. Additionally, replacing the oil beforehand will give you one less task to do when the following season begins.
5. Unplug your battery and use Yamaha Battery Terminal Protector & Cleaner on the battery connections.

How do I prepare my Yamaha outboard motor for a new season?

When the cold weather ends, you can start to use your Yamaha outboard motor once more. Before you install the outboard in the water, there are some steps you need to take.

1. Prior to discarding the engine cover, it is necessary to clean it with a soft brush and a detergent meant for canvas such as Star Brite Sail & Canvas cleaner.
2. After taking off the cover of the boat, it is important to do a thorough examination of the engine. Check to see if there are any fluids that have leaked out from beneath the engine, such as transmission oil, motor oil, trim liquid, and fuel. Pay special attention to any marks or stains that may indicate a leak.
3. Guard your boat against UV radiation - A coat of wax can help to keep your boat safe from UV rays. If the exterior of your boat looks dull, you can use a polishing agent before waxing to restore its original sparkle.
4. When putting batteries away for the winter, it's important to unplug them and take a look. Check for any signs of damage, such as bulging, leaking, oxidation, and signs of wear and tear.
5. It is important to take the time to assess bilge pumps, float switches, and freshwater systems. Make sure the float switches are correctly wired and functional whether the battery switch is on or off. Additionally, check that the bilge pump can be manually turned on, and that the necessary components like the wiring, discharge hose, hose clamps, and thru-hull fitting are all in working order. If the boat's freshwater system was winterized, fill the tanks and get rid of the antifreeze according to the manufacturer's instructions. A product such as Spring Fresh can be used to flush the freshwater system and remove any remaining antifreeze.
