I will try to post a better picture. 
I have two new 3 3/8" diameter Smartcraft Gauges to install.
The holes in the boat as originally equipped has one 3 3/8" hole and four smaller 2 1/8" holes.   I have lots of options on where to put them.  Including front and center next to the GPS Combo.  
Any suggestions??
