Yamaha is a very reputable brand that makes recreational vehicles that everyone is familiar with. From jet skis to four wheelers to boats, Yamaha is a brand that you know you are getting the best bang for your buck, and has very few competitors that come close to the quality and power. More specifically with Yamaha outboards, it is great to have a boat that you know will get you where you need to go, and is reliable to boot. Think how disastrous it would be if you were out on a fishing trip, going farther than you are used to in order to find a great catch, but then your boat engine sputters and dies. It would make for a very terrible, but also dangerous fishing trip. This is why it is always advisable to do regular maintenance on your engines even if you buy a good brand like Yamaha. You might find that many Yamaha recreational vehicles and boats have different motor oils. It is best to note that you cannot just use a car oil for your jet ski or boat engines. Even more specifically, jet skis and boat engines use separate motor oils. For your Yamaha outboard, the appropriate oil to use is the yamalub 2-M.
Some people with multiple Yamaha “toys” might think, what is the big deal if I mix up and switch up between the Yamalube 2W and 2M oils? For one thing, is make for waverunners, (their jet ski line) and sport engines (think jet boats), and the Yamalube 2-M is specifically made for outboards (their boat engine line). Getting and using the 2M for your outboard can provide wonderful results. For one thing, the oil helps with keeping the carbon down. This is incredibly beneficial to the environment as client change is increasingly hard to avoid and ignore these days.
Sure, you could get a motor oil from the big box brands, but by sticking with the Yamaha family, you get what you pay for – Furthermore, you get peace of mind that the oil you are using is specially designed for your boat’s engine, and therefore you are using the best and most appropriate oil that is going to prolong your engine’s life, but also be good for the environment. No one wants to be near or behind the boat that is chugging out black fumes. Boating is already such a social activity as it is.
