[QUOTE="thill, post: 493713, member: 4972"] Take the air box off (if it has one) and look down the carb and watch the butterfly while throttling up with the engine OFF, not running. At full throttle, the butterfly should be perfectly horizontal for maximum airflow. If your throttle cable is out of adjustment, it will open fully, and then continue past horizontal and close partly in the other direction. This will cause the motor to slow down. So you may actually be at full throttle when the handle is only turned 3/4 or so. I had this issue in the 25 Evinrude in my sig pic years ago, and someone here helped me. You may need to do a "sync and link" according to the service manual to get everything working properly. [/QUOTE]
