"I have a a 1991 70HP Mercury Outboard that will not start. My problems started when I used gas with Ethanol. I never had a problem with the motor before.
At first Ethanol clogged up my filters and made the motor hard to start. I solved some of the problems and was using the boat with some starting difficulties. Now I can't even get a spark out of it.
