The steering on our 135 evinrude has "locked up" The trouble appears to be associated with the ram and control arm mounted on the back of the motor, it appears to be mechanically rather than hydraulically operated. First instincts are to grease it up and try and "rock" it free by rotating the motor back and forth. Is this a good idea or am likely to bend/brake something else?<br /><br />thanks in advance<br /><br />dm
