How do I use Yamaha outboard schematics?

Picking Yamaha original parts (OEM) is usually more beneficial than choosing after-market items. For instance, if you install a faulty outboard component and it causes major engine issues, then you may invalidate the warranty and end up paying more for repairs in the long run. Our extensive list of Yamaha-compatible parts provides a variety of solutions for those older Yamaha outboard models that are no longer supported by Yamaha.

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

Frequently used Yamaha outboard head gaskets may experience degradation due to exposure to high temperatures, saltwater, and other elements. If the head gasket is not changed when it starts to become worn, water will be able to seep into the motor. When this occurs, the outboard's performance will be hampered and can eventually result in extensive 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:

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?

When it's time to store your Yamaha outboard engine for the winter, it's essential to take the necessary precautions in order to avoid any damage and to have a successful start to the following season. Putting your boat away is not as enjoyable as taking it out, but there are certain steps you must take to winterize the lower unit of your Yamaha outboard.

1. Flush Your Engine - If you are a saltwater boat user, it is necessary to flush your engine completely to get rid of any salt accumulation. The same goes for freshwater boaters, who need to clean away any mud and dirt. Failing to get rid of this debris can lead to corrosion in the motor. Saltwater boat users should pay special attention to salt crystals in the lower unit, as these can cause a great deal of damage.
2. Stabilize Your Fuel System - It is essential to add a fuel stabilizer such as Yamaha Fuel Stabilizer and Conditioner Plus to your fuel if your boat will not be used for more than two or three months. The instructions on the packaging will tell you the amount of fuel stabilizer to use, usually 1 ounce of Yamaha Fuel Stabilizer and Conditioner Plus per gallon of gasoline when the engine is stored for a period of over two 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 suggest that you replace the Yamaha gear lube before putting it away for storage to assure there is no water in the gear oil for the lower unit. If water is present, it could freeze and cause damage to the lower unit. Additionally, changing the oil prior to storage will have you one step ahead when it comes to getting your boat ready for the next season.
5. Disconnect Your Battery - Unplug your battery and apply Yamaha Battery Terminal Protector & Cleaner to the contacts.

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

When the winter weather has passed, it's time to prepare your Yamaha marine engine for use. Prior to installing your outboard, some steps will need to be taken.

1. Uncover & Unwrap - Before taking off your outboard engine cover, it is important to clean it using a soft brush and a specialized cleaner such as Star Brite Sail & Canvas cleaner, which is designed for canvas fabrics.
2. Walk-Around Inspection - After removing the cover of the vessel, the subsequent action in the Yamaha outboard startup is to conduct a thorough visual examination. Look for any liquid spilling beneath the boat, particularly close to the engine. Potential sources of any stains or seepages could be gear lubricant, motor oil, trim liquid, and petrol.
3. Protect Your Boat from UV Rays - To shield your vessel from the sun's ultraviolet rays, you might want to think about coating it in wax. In case you can tell that the hull has become dull, putting on a polishing agent before waxing it will make it sparkle.
4. Battery & Electrical System Assessment - A lot of boaters take out or separate their batteries for safekeeping during the off-season. When hooking them back up, examine the batteries with the eye to look for any signs of physical damage, leakage, decay, and age.
5. Inspect Bilge Pumps, Float Switches & Fresh Water Systems - Float switches and bilge pumps are fundamental safety equipment that deserves a thorough examination. It is essential to ascertain that the float switches are correctly wired so that they will work even with the battery switch off. The majority of boats are set up so that the operator can manually switch on the bilge pump. Ensure that the pump operates correctly and the wiring, the discharge hose, hose clamps, and thru-hull fitting are all in perfect condition. If the freshwater system has been winterized, fill up the tanks and expel antifreeze in accordance with the manufacturer's instructions. Consider using a product such as Spring Fresh to flush the freshwater system and eradicate any lingering antifreeze.
