Yamaha Outboard Service Kits FAQ
How do you grease a Yamaha outboard engine?
Greasing your Yamaha outboard is an important part of keeping the motor functioning. A grease gun is an important part of maintaining your Yamaha outboard motor. To do this, you load a tube into the grease gun and use a trigger-activated plunger to slowly dispense the grease as needed into the grease points.
Grease points are metal fittings attached to your outboard motor that allow grease to be fed into the system under moderate to heavy pressure. Because you don’t have to remove most engine components to access the grease points, they’re easy to work with. To find grease points on your outboard, refer to your service manual for your particular Yamaha model outboard and add grease where grease “A” is specified.
How do you perform a Yamaha outboard leak-down test?
An outboard leak down test is a simple diagnostic checkup for your Yamaha outboard – and it can even be incorporated into your regular maintenance intervals for peace of mind.
A Yamaha outboard leak down test indicates the condition of each of the Yamaha engine’s cylinders and the overall condition of the motor. Similar to a compression test, it involves spraying compressed air into each cylinder and using a pressure gauge to measure a percentage of pressure that’s lost as compressed air after a short period.
Part of performing a leak down test on a your Yamaha outboard motor is to listen for any signs of leakage. By listening closely to each cylinder and the areas around them, you’ll better understand where leaks may be present.
-
Step #1: Carefully remove the top cowling, Then, remove the ignition coil cover at the rear of the motor.
-
Step #2: Remove the spark plugs.
-
Step #3: Remove the flywheel cover from the top of the motor.
-
Step #4: Mark the flywheel with a marker at 0°, 120°, and 240°. These positions indicate where you’ll rotate each pair of cylinders to the top dead center positions (see Step #11 and #12 below).
-
Step #5: Rotate the crankshaft with your ratchet and socket to the top dead center for cylinder #1.
-
Step #6: Adjust the regulator on the leak down tester to 0% to calibrate it for an accurate reading.
-
Step #7: Connect the leak down tester by screwing into the spark plug port at cylinder #1. Next, connect the tester to the compressor and take a measurement. Be sure to firmly hold the crankshaft to prevent it from rotating.
-
Step #8: Rotate the crankshaft 360° (one full rotation) to put cylinder #4 at top dead center.
-
Step #9: Connect the leak down tester to cylinder #4. Then, take a measurement while holding the crankshaft to prevent it from rotating.
-
Step #10: Set cylinder #3 to top dead center at the 120° mark. Next, repeat step #7 through Step #10 for cylinders #3 and #6.
-
Step #11: Set cylinder #2 to top dead center at the 240° mark. Then, repeat step #7 through Step #10 for cylinders #2 and #5.
Step #12: Replacement is the same as disassembly. Be sure to replace spark plugs in numbered order and apply anti-seizing compound on the threads for easy removal/replacement in the future. Also, firmly reattach spark plugs to the ignition wires for a solid connection.
What are common Yamaha F115 4-stroke outboard problems?
The Yamaha F115 is an excellent 4-stroke outboard motor that consistently receives high marks for reliability, longevity, and performance. As with all marine outboard motors, with enough continual use and exposure to the elements, Yamaha outboard parts will begin to wear. Because of this, regular maintenance and servicing are required to keep this outboard motor in the water and out of the shop.
The following are 5 of the most common Yamaha F115 4-stroke outboard problems:
-
Faulty Head Gasket - Over time, the head gasket of your Yamaha F115 is regularly exposed to a number of elements that reduce its integrity, such as salt water, heat, fuel, and other substances. Once a head gasket fails, water and other contaminants will enter your engine. When it comes to Yamaha 115 4 stroke problems, replacing the head gasket should be a priority every 4 years of service, or sooner if usage exceeds the average boater (50 hours per season, or 200 hours for 4 years).
-
Bad Fuel Pump - A bad Yamaha fuel pump is one of the most common problems for Yamaha 115 4-stroke outboards. When the fuel pump finally gives out, your motor is essentially dead in the water until it is fixed. Fortunately, bad outboard fuel pumps are easy to replace and repair. They’re also relatively inexpensive when compared to other necessary engine repairs.
-
Clogged Fuel Injectors - Over time, carbon build-up clogs fuel injectors and prevents a smooth distribution of fuel. When carbon clogs the fuel injector, your outboard will often misfire, vibrate excessively, and bog down during idle or when the throttle is applied. Cleaning your outboard fuel injectors with fuel injector cleaner keeps clogging from occurring and your Yamaha outboard motor performing at its best.
-
Clogged VST Filter - Regularly replacing your Yamaha 115 4-stroke’s VST filter prevents clogging. There are plenty of kits to help clean and/or replace your VST filter for proper fuel system maintenance. If this service isn’t performed regularly, your Yamaha outboard engine may require a more time-intensive and expensive repair.
-
Trim and Tilt Problems - A faulty trim and tilt switch can prevent you from the fine-tuning (trim) and dramatic changes (tilt) needed for optimal performance of your Yamaha F115. Luckily, you can avoid these problems by swapping out the trim and tilt switch on your Yamaha outboard motor.
Why are there so many types of Yamaha outboard fuel filters?
The reason why there are so many Yamaha outboard fuel filters is rather simple– dirt comes in various shapes and sizes. Some dirt particles are larger, while others are essentially dust particles. Some materials you can easily see, other materials can be microscopic biological growth and may still be growing.
Dirt also takes different shapes. Some may be shaped like a ball, while others, like an arrow. Ball-shaped dust is typically caught easily, but the arrow type may penetrate the first and second filter and get stuck in the third. Once the arrow lays across the filtering medium, it partially closes the passage holes and makes them smaller, capturing even smaller debris. This leads to clogging. If the initial filter is restricted, the vacuum on the filter may suck the debris through it and on to the next filter, and so on.
Poor fuel quality, water, ethanol, lack of fuel rotation, and biological growth all add up to clogged Yamaha fuel filters. This is why it’s essential to change all Yamaha fuel filters on a regular basis based on factory guideline recommendations. Many of our Yamaha outboard service kits come with fuel filters to make the process simple.
Some Yamaha four-stroke outboard engines require several of the fuel filters below or screens to help prevent water and debris from getting inside the engine.
How do you perform a Yamaha outboard motor oil change?
Performing needed maintenance in a timely manner on your Yamaha outboard is the key to its overall longevity and reliability. Use one of our Yamaha outboard service kits to perform a quick and easy oil change on your Yamaha outboard.
Can I use a Yamaha F150 100 hour service kit in place of a Yamaha F250 100 hour service kit?
No, you should not use a Yamaha F150 100 hour service kit in place of a Yamaha F250 100 hour service kit. While both kits may contain some similar items such as oil filters and spark plugs, there are likely differences in other parts such as the fuel filters, water pump impeller, and other components specific to each engine model.
Using the wrong service kit for your Yamaha outboard engine can result in improper maintenance or even damage to your engine. It is important to always use the correct service kit that is designed specifically for your engine model and year. If you are unsure which service kit is right for your Yamaha outboard engine, it is best to consult with a qualified mechanic or refer to the owner's manual for guidance.
