Running back from the Bahamas today oil buzzer went off. I throttled back heard some rattle and when I got to idle she quit. Found I busted an oil line so she was definately hurting. Too rough to try and fix out there. At first she wouldn't turn and I figured I siezed something up but back at the dock she started to turn but slowly. That could be because my battery terminals frequently loosen up or?????????? Starter is one of those big internal ones and both front and back of engine are turning all be it slowly. So seized or busted crank aren't in play... Any ideas?
