The Verado system was really designed for multi engine use, many of which go into offshore fishing boats. Their fly by wire binnacle, and SmartCraft gauges are also designed to interconnect with auto pilots, GPS's, etc. You've just about got to be an electrical engineer to figure out what wiring harness is required, and few marine technicians have that knowledge.
I don't cherish spending $3K-$4K labor to mount a motor, and another $3K-$4K in gauges and hardware to hook it up for a single engine application like a tritoon. That's just more things that can go wrong.
The Yamaha can be hooked up with regular cable operated throttle/shift binnacle, and it can use regular analog gauges. You can go fly by wire if you'd like, but it's not required as the Verado is.
Since I'm always in sight of land, and the farthest I can be from home on my lake is 12 miles, I have no reason to spend a fortune for high tech features that I'll never use. Heck, I'm just glad to have a GPS speedometer on my new Bennie, and I like to keep my life simple.
