I have a 1976 omc slick craft, I bought it last year as a project. I have been rewireing the boat after some one butchered it. I finally got ready to test start the engine. I went to tilt the out drive and it dosnt do anything. I removed the tilt motor and it works fine out of the drive. So I thought I would just bump the engine, it won't do anything but melt the battery post. I can rotate the engine by hand though. So I wondered is there something in the drive that could be causing the problem? Any thoughts or ideas. I will mention I am a mechanic on heavy equipment for a living. But before I remove the engine or the out drive I wanted to ask. Thank you and sorry for the long post
