So I was looking to decarb the motor so i popped the top and was familiarizing myself with this foreign object known as an outboard (be easy on me I'm a network engineer not a mechanic) and thought that I was looking at three separate carbs so my question is, is this right? normal? How many barrels do the carbs they "normally" have? BTW, 1991 Evinrude "xp" 150HP. OK, thanks dudes.
