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

    Changing the gear lube of your Yamaha outboard motor is essential for ensuring its longevity and smooth operation. Having the parts and products on hand (like Yamalube gear lube) makes performing this critical maintenance step a breeze.

    The following are the top five reasons why a Yamaha marine gear lube kit is a convenient tool for keeping your Yamaha outboard motor running smoothly for years to come.

  • Increased Yamaha Outboard Lifespan - Your Yamaha outboard engine starts to degrade from the moment it hits the water. This is especially true if your engine is used heavily, allowed to corrode, is improperly stored, and improperly maintained.
  • DIY Outboard Repairs Save Time and Money - In just a few hours, you can change your Yamaha outboard oil, replace routine parts, and lube up your engine. And, all for a lot less money than a local marine mechanic will charge.
  • Change Your Yamaha Outboard Lower Unit Oil - Oil and grease are the primary lubricants that keep your outboard in the water and out of the repair shop. PartsVu.com’s Yamaha marine gear lube kits ensure you have the right kind of oil for your engine at premium quality. 
  • Maintain Regular Outboard Service Intervals - Yamaha outboard motors require regular maintenance to stay reliable out on the water and avoid breakdowns. This maintenance must occur after 20 hours of service for new engines, then every 100 hours.
  • Convenience - PartsVu.com’s Yamaha marine gear lube kits have everything you need to perform gear lube changes and help prevent buying the wrong item or compromising on quality. This includes: Yamalube gear lube, Yamaha gear lube pump, and Yamaha outboard lower unit drain gaskets.
  • What are some tools to help me to find the right Yamaha outboard parts?

    PartsVu.com has plenty of resources to help you find the correct Yamaha Outboard Parts to keep your Yamaha outboard engine performing on the water. 

  • PartsVu’s Yamaha Outboard Maintenance Parts Charts
  • Yamaha Specs & Capacities Charts
  • Yamaha Outboards Engine Schematics
  • PartsVu offers more than 40,000 Genuine Yamaha OEM parts and products and other boating essentials at low prices.

    How do I use Yamaha outboard schematics?

    Looking for even more specific and in-depth information for maintaining or repairing your Yamaha outboard motor? PartsVu offers Yamaha Outboards Engine Schematics. By clicking on this link, you will be taken to Yamaha’s schematics page. Once there, you will choose the right parts for your Yamaha by searching either by your outboard’s Primary Identification Number (PID) located at the top of this page or look up your model using a series of dropdown menus on the left side of the page.

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

    Like most outboard components, Yamaha outboard head gaskets wear down through usage over time. When head gaskets are regularly exposed to excessive heat, corrosive saltwater, and other substances, their integrity will eventually lessen. If a head gasket is not replaced when it begins to fail, water will begin to enter the engine. Once this happens, the performance of your outboard will be significantly affected and eventually lead to major engine damage.

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

  • Reaching the 4-Year Mark
  • Low Pressure in the Cylinders
  • Water Coming Out of a Spark Plug Hole
  • Black Specks, Crud, and Slime in the Cylinder
  • Idle Runs Too Slow or Rough
  • Holes In the Head Gasket
  • Is winterizing my Yamaha outboard important?

    While it’s always a bit more fun to pull out your boat than to put it away, properly winterizing your Yamaha outboard engine avoids engine damage and will facilitate a smooth start to the beginning of next season. There are several important steps you should take when storing your Yamaha outboard lower unit to ensure that it’s properly winterized.

    1. Flush Your Engine - It’s important to thoroughly flush your engine to remove any salt buildup if you are a saltwater boater, or general mud and grime if you are a freshwater boater. Failure to remove this debris can cause or contribute to corrosion in the engine. If you’re a saltwater boater, salt crystals in the lower unit can cause a great deal of damage.
    2. Stabilize Your Fuel System - It is vital to use a fuel stabilizer like Yamaha Fuel Stabilizer and Conditioner Plus when your boat will be sitting unused for any more than two or three months. Add the amount of fuel stabilizer directed on the product’s packing to your fuel—for instance, 1 ounce of Yamaha Fuel Stabilizer and Conditioner Plus for every gallon of gasoline, assuming the engine will be stored for more than 2 months. 
    3. Fog Your Engine - Yamalube fogging oil is a wax-based oil that coats the engine and prevents corrosion.
    4. Change Lower Unit Oil - We strongly recommend changing your Yamaha gear lube before storage to make sure that there is no water in the lower unit’s oil. Any water in the oil could freeze, expand, and crack your lower unit. Also, changing lower unit oil means one less thing to do at the beginning of next season.
    5. Disconnect Your Battery - Disconnect your battery and spray Yamaha Battery Terminal Protector & Cleaner on your battery terminals.

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

    Once the cold season is over, it’s time to break out your Yamaha outboard motor again. But there are a few things you’ll need to do before putting your outboard back in the water. 

  • Uncover & Unwrap - Before you wad up your engine cover and put it in a trash bag, the fabric itself should be cleaned using a soft brush and a canvas-friendly cleaner like Star Brite Sail & Canvas cleaner.
  • Walk-Around Inspection - With the cover off the boat, the next step in Yamaha outboard season breakout is a careful walk-around inspection. Check for any leaks under the boat, specifically below the engine. Gear lube, engine oil, trim fluid, and gasoline are possible causes for any leaks or stains. 
  • Protect Your Boat from UV Rays - Consider a coat of wax to protect your boat from UV rays. If you noticed your hull is chalky, applying a polishing compound before waxing will bring out a bright shine.
  • Battery & Electrical System Assessment - Many boaters remove or disconnect their batteries for storage during the offseason. Before reconnection, visually inspect batteries for evidence of physical deformation, leakage, corrosion, and age.
  • Inspect Bilge Pumps, Float Switches & Fresh Water Systems - Float switches and bilge pumps are critical safety gear that is worth the effort to inspect. Properly wired float switches should function with or without the battery switch being turned on, so be sure to check both ways. Most boats are also wired so that the operator can manually toggle the bilge pump on. Verify that the pump runs properly and that your bilge wiring, discharge hose, hose clamps, and thru-hull fitting are all in great shape. If your boat’s freshwater system was winterized, be sure to fill your tanks and flush antifreeze from the system, and dispose of it per the manufacturer’s recommendations. Consider a product like Spring Fresh to flush the freshwater system and clean the lines of any remaining antifreeze.
