How to Maintain Yamaha Outboard Motors for Beginner

Failing to maintain the Yamaha outboard motor on your boat is the fastest way to ruin a great day on the water. Even worse, your motor failing can also put you in danger of hitting other boats, washing ashore on rocks, or going adrift-not a good way to end a nice day on the water, right?

The good news is that you can maintain your Yamaha outboard motor with ease. The secret is to have a high-quality Yamaha outboard manual on hand, providing the correct information to keep your boat motor running for years, while keeping related expenses as low as possible.

And as you'll see below, outboard mechanics isn't that complicated at all!

Basic Boat Motor Maintenance

Like your car engine, your boat motor will need to have the filter checked regularly, and the oil will need periodic changes (on four-stroke units only). Luckily, even common jobs, like replacing your pull cord starting cable or adjusting the carburetor throttle, require only a bit of practice, some basic hand tools, and a reliable manual.

Indeed, Yamaha OEM service manuals teach you the right way to handle basic repairs and could make the difference between a good day and a disaster. And no need to mention, you'll save a lot of money by servicing your motor yourself instead of taking your boat to a repair shop.

Major Services

Yamaha outboard engines are quite reliable but also require continuous maintenance and regular servicing to stay so. The company provides a maintenance schedule on its website, but you can get more information in a Yamaha shop manual. Notably, it will guide you through the process of servicing your outboard engine, even on major services that Yamaha says should only be done by a professional mechanic.

How Often Does a Yamaha Outboard Motor Need Service

The Japanese manufacturer lists initial servicing that you should do after 20 hours of use (3 months), every 100 hours, 200 hours, or 300 hours. Most common services include engine oil inspection and replacement (every 100 hours), battery inspection (every 100 hours), fuel filter replacement (every 50 hours), and water separator (every 100 hours).

You should also inspect the cowling clamp, fuel lines, and spark plugs every 100 hours, and change the gear oil and lubricate the grease points at the same time.

Luckily, you can do all of these things without previous knowledge or special tools. Still, a Yamaha outboard manual will undoubtedly make everything easier here since it will guide you through the process step-by-step. It will also provide you with information about which oil to use, the recommended torque for the screws, etc. Don't already have one? Take a look at eManualOnline. Their Yamaha service manuals are super easy to use and cost a lot less than a single visit to the repair shop.

Still don't want to get your hands dirty? Of course, professional service centers can help you here but cost significantly more. Nonetheless, they offer complete services, including monitoring the engine's compression, replacing spark plugs and fuel filters. Several other checks, replacements, and repairs are part of the annual service. But, once again, these services will be much more expensive than doing the job yourself, though.

Improving the Performance of Your Outboard

Your Yamaha outboard is a high-performance engine, but you can always squeeze a little more without having to tune the engine. Particularly, you can play with other propellers - some are better for acceleration, others for top speed.

Adjusting the trim angle of your boat is another great way to improve performance. The best advice is to make sure your boat sits even on the water, although you might need to experiment and see what works best for you.

You also need to make sure the roostertail from the back of your boat is smaller. It is an indication that the engine provides more forward thrust, rather than just using its power to shoot water into the air.

Worth mentioning, such tweaks won't damage your outboard motor in any way, unlike tuning could. Keep in mind that tuning any engine can lower its lifespan, and that's especially true for outboard engines.

Final Thoughts

One of the most important things (and also the simplest) you can do to keep your Yamaha Outboard motor performing at its best is to run it regularly. That means getting out on the water and having a great day.

Of course, using the motor more often also means that you'll need to service it more often but it's nothing you can't take care of with the help of a Yamaha shop manual. Moreover, these motors are also a pleasure to work on, and you'll gain knowledge and pride that you can keep your outboard motor running perfectly, all while keeping expenses on the lower side-what's not to like?
