When I got a very small outboard that I would be able to use on a small boat on the lake next to my home my house, I was unsure what kind of oil I could use with it. I had to look up a lot of information about this to determine what was really necessary. I knew I would use quality oil, but I had to find what type was the type that I would definitely need.
I was able to find a few different types of oil that seemed to have the right formulation for an outboard of this size. I decided that it would probably be the best if I bought some oil from Yamaha since this was a good brand of oil. I finally determined that Yamalube 2M would be the right type of oil for me to use in this small outboard motor.
