i have a seastar system on my boat, turning the yamaha f225 on a bracket.<br /><br />yesterday i noticed while on plane, i could feel and hear a sort of "hum" coming from the steering when turning to port. not there when turning to starboard.<br /><br />off of plane, it goes away. turns effortlessly in both directions.<br /><br />no idea if this was here when i bought the boat, or if it's something new. any suggestions where to look first? not too fluent in these systems just yet. thanks-
