I have an evinrude 150 ficht yr 2000. I heard all the horror stories but this motor has been running great. The problem started last season. The motor sputters like it is loosing fuel. I took it to a local marina and they told me water was gitting into my pistons and it needed new o rings. They replaced them and it ran fine for a couple months. The problem came back again and I changed the O rings myself it didn't look like they needed it but it ran great for a nother couple months. Now the problem is back. I looked at the orings again and they look fine. There is some carbin in there but I don't think that is the problem. I called the marina and they told me I should buy a new motor. I don't think so. I would appreciate any help you could give me. I called evinrude and they sound like they don't have a clue.
Thank You
