I have a 28hp 1988 Evinrude, just today out of the blue the starter was just spinning and not lifting to the fly wheel. So the first thing I did was test the battery voltage, well it was under 12. I replaced the batter today with a brand new one just to be sure, wired it up, and turned the key, same thing.... I'v checked all the connections, roughed them up, all look fine... Also I should mention that manually lifting the starter, seems to lock up, I can't lift it to the fly wheel, is that normal? Any ideas?
