Wow, after reading this article, I'm glad my next boat has a 4 stroke motor! There's a bigger picture than just oil going into the water... Pollution into the air is also an issue associated with "2 smokers". Not gonna lie, I used a 2 stroke motor for 5 years up until I recently sold my boat and I loved it. Simple to maintain when compared with some of the newer 4 stroke motors. But dang, it was definitely a smoker! One thing is for sure... Gonna be nice not having to buy oil every couple of trips! D-Wayne, don't mind gonefishing. He's a bit angry at times lol
