Yesterday I was riding on the river & all seemed well. Then all of a sudden my motor just up & died!! I tried everything to start it but it wouldn't crank so I had to be towed in. :mad: When I got it home, I realized it had no spark on any of the 3 cylinders. I bought new sparkplugs & put them in. Still nothing. My neighbor told me that it could be the stater, so I took it off, but it looks fairly new, so I doubt it is that. I really hope someone can tell me what the problem is. I know a lot about car engines, but I'm not too familiar with outboards. Can somone please help me? :confused:

Did you accidently pull the tether switch if not, do you have a OHM meter we can get you a systems test if you have one or a DVA.
