rudder angle on single screw

[Capn Chuck]

Sorry the thread degenerated away from your question. You have two possible issues. One is that the cylinder is positioned wrong. In that case, remounting it making sure that the cylinder is in the center position and the rudder is also, is important. The other issue could be the cylinder itself is the wrong size. I would verify the size issue first before remounting anything. Then again it could be a Mainship engineering quirk and checking with other owners of like boats will tell. Chuck
