When I first owned a boat, I also owned an outboard that was old and not particularly energy efficient. I often wondered what my boat might be doing to the water since the motor puffed out huge plumes of smoke whenever it was running. When I had the money to replace the outboard motor, I decided to get something that would run a lot cleaner.
I understood that if I wanted to preserve the waters that I was going out on, I would need to find an engine that would run with less exhaust. I looked at a few different ones before picking out an Evinrude E-Tec outboard. As long as I run the right kind of Evinrude outboard oil in it, I don’t have to worry about my engine churning out all kinds of exhaust.
