I have a 1997 120 hp Force outboard that has been sitting for quite a few years before i bought it. I would like to know step by step possibly what i need to know to get this thing starting again. I have gotten to the point where the battery is hooked up and it turns over. But it wont start up. I replaced the gas and oil mixture cause i figured that would be bad and i replaced the spark plugs, and got a new battery. What do i need to do?
