Texas Dan…I know it might cost you just a bit more, but the Helix 10 Mega SI, with the transducer mounted to the starboard side of the jackplate with a Transducer Saver and L bracket. The 9″ and 10″ are exactly the same case size, and will fit in the console with no problem. The difference is the 10 has a LOT better resolution in pixels per square inch.I ordered my boat (a 17 model) with the Helix 7 SI in console and 7 DI up front. They did not offer the Mega units at that time. I ended up putting a 10 Mega SI in the console and moving the 7 SI to the front, along with the upgraded HD transducer, and it has worked out perfectly. I also had BassCat install the wiring connection to get information from the 175 SHO ECM, and had them install the NMEA 2000 backbone, dongle to convert that signal to Ethernet, then added the Ethernet 5 port box to hook it all together. The Helix models cannot share much, other than waypoints, transducers, etc through the Ethernet connections. What it CAN do (the Helix 10 Mega) is display engine temperature, oil pressure, RPM, fuel flow (gallons per hour), and other stuff if you have the engine sensors…like water pressure.Just something to consider…
