    Question 85, OMC 3.0 I/o engine lo up.Crank won't turn. What could it be?

    85, OMC 3.0 I/o engine locked up.Crank won't turn. What could it be? Could an overhead valve be locking it up or the transmission? Could the starter keep the crank from turning?

    Pull the outdrive. You'll get a better idea of where the problem is.
