Question: I have a new 150 Pro XS that I just finished breaking in for 5 hours. When I was at 5600 rpm I could hear a whirl whirl whril sound coming from the moter. The sound cycled from high pitch to mid range pitch. Runs great 60 mph gps on new Z-7 but just sounds funny. Had 200 Opti before that was a gas guzzler but never made this noise.
