This may seem like a stupid question to some, but Ive been looking at a boat to buy and it has a 2003 mercury 60hp on it. I was wondering if it was a 2 stroke or 4 stroke? How would I be able to tell? It has 3 spark plugs and the model number is 1060412ad. And also what type of oil would it take? If anyone could help that would be great... Thanks!!
