I have a mercury 9.9 I think it is an '88. The engine misses out when it is cold. It just started a few weeks back and it is getting worse. Someonne told me it could be the coil. Any advice on checking it and replacing it.

Re: merc 9.9 missing out

From what you describe, it doesn't sound like a coil problem to me. Usually intermittent ignition problems show themselves when the engine gets hot not when it's cold. I'd lean toward a thorough carb cleaning/rebuild.<br />Backlash
