I have a 1987 evinrude 20 hp E20CRCUR tonight I was running it and she sputtered and stopped running. I attempted to start again but got not turn over (spark). What kind of spark plugs go in this thing, I guess I should start the trouble shooting at the spark. It ran fine all night untill the end of the night. I did not smell anything burning and it was peeing water. I am running 50 to 1 instead of 100 to 1. I also run it slow on alot of occasions but tonight I ran it WOT for roughly 6 miles. It is a rope start. What can the problem possibly be? Thanks
