Hello can someone help me to have the best view on my transducer. If you could draw a line on the photos I posted of where the best placement is for this boat. Much appreciated. 

I forgot to add I want the best location for idle speeds. I was told I need two transducers for idle and plane.  

What kind of units?  What type of transducer are you mounting on the outside?

Garmin gt56

Might give Garmin support a call. I've had good luck with them troubleshooting when I had problems.
