I just picked up an older boat '97, with a 97 Mercury 120HP Tracker. I've been informed from the previous owner its a premix. I have two questions: A) does anyone know if its a 2-stroke or a 4-stroke? I'm in the process of trying to obtain an owners guide so i can reference parts if i ever need to in the future.<br />B) What kind of oil would anyone suggest for this year/make/hp? Thanks.
