Just got this boat and motor. Runs Great except for this annoying problem. If I'm cruising at 3500 rpm's and want to bump up to 3800 it will stay at that rpm for about three seconds and return right to 3500. Also if I'm at 2800 and try to bump up to 3000 the rpms will start climbing and settle right about 3300. My lever in my control box feels nice and tight. Is there some kind of throttle position sensor in this motor? <br /><br />Thanks
