"I have posted on here before and I would like to thank you guys for your help. I have a 1995 3.0 mercruiser alpha one lx and it has a rough idle. It runs fine but when at idle it is just a little rough. I first took it out after I bought it( it was the first time out in two years for this boat) and it would cough when trying to start and I would have to drop the throttle in neutral to get it going. Naturally thinking it was the gas, I got some b12 chem cleaner and put it in the gas. It seemed to run better. However I pulled the sparkplugs today and they were all black. Is this a fuel issue or is there something else that needs to be done?
Thanks so much"
