I had this unit mounted on my 27' Grady White w/twin 200 Yamaha engines last year. However, at trolling speed the unit held it's course on most occaisions however, at cruise speed (3500-4000 rpm)without warning after a few minutes the boat would turn hard to the starboard, on one occaision throwing a crew member out of the boat!<br />This happens on a less frequent bases while trolling.<br /><br />Does anyone have any idea what the problem is and what the fix is???? Thanks!
