First off i just want to thank all of you for these forums, they have helped me immensly! I have a 1974 Evinrude 50hp model #50473M. I have the CDI troubleshooting guide and have done the first two "easy steps". Here is the thing, the boat will run one day, and not the next. I ran it for 15 minutes at the house and it did great, drove to the lake, backed it down the dock and it wont start. Pull it out, and after a little work it starts. Needless to say i did that two more times and i gave up. I drove home "this was monday" I have tinkered with it since and cant get it to start. This morning i walk out of the house and it fire's right up, tonight no dice. I know that i am getting fuel, and that is not the problem. I Have pulled the plugs and i am not getting spark from either coil. I have also pulled the two yellow wires and no spark, i have also pulled the black/yellow wire and no spark. It has me a little baffled that it will start one day and not the next. Any helpful hints will be greatly appreciated Thankyou in advanced!!!!
