Trusting Evinrude Oil in an Evinrude Motor

My friend recently purchased a new boat. He ended up buying a used motor to go with the boat, since it did not come with one initially. It was an Evinrude motor that one of his friends had for a boat that they no longer chose to use anymore. My friend spent several hours reading up on the motor online, so that he could learn more about it.

He wanted to make sure that he could keep the motor running perfectly. He learned what kind of Evinrude oil needed to go in the motor, exactly how much oil to use, and what other maintenance needed to be performed regularly. He got a checklist of some of the required maintenance and decided to start fresh by getting these things done right away.
