Well, this isn't good. At the very least we hope you were on land when you found out it was broken. With that out of the way, let's talk about getting it fixed. You're going to need parts. Maybe just one Evinrude outboard motor part will be enough, but maybe it'll take a whole batch of them to get this old engine running again.
