I recently purchased this motor. I've had it out 3 times so far. The first time everything was good. Followed the break-in procedure. I store the motor upright on a motor stand. Now the motor tops will only go approx. 5 mph. I have it on a 14ft. aluminum with a 25hp Johnson. No extra gas tank or anything. I've tried tilting at all positions. Engine sounds like its bogged down or something at full throttle. Something isn't right, but just don't know what. Any help??<br /><br />Thanks a bunch.
