Is anyone using on this on their RT188? I just bought 2 HDS Carbon 9's to upgrade my old Gen 2's. Does it require the steering wheel spacer? When I bought my RT originally the dealer removed the factory depthfinder, put a cover over the hole and installed my Merc Monitor sc1000. Obviously I don't want to lose that gauge, but I'm not sure where else to put it.
Also what about a Balzout mount, mounted next to the console? Is the base small enough to mount next to console? For reference, I'm referring to the flat area above the shifter. I had a balzout mount on my old boat, and remember the base being really big.
