The 6YC is easy to read, especially the very large RPM / trim level and fuel bar graphs. I get mesmerized looking at the smaller numbers: speed/econ/fuel flow rates as we cruise.
One issue I have is no data for my engine water temperature. Not sure if this is related but my Garmin 53dv has a problem with it's
transom mount transducer which provides lake water temp, depth and fish finding sonar, none of these are working either. I tried wiping/cleaning it and look but was not able to find any loose connections under the helm, will wait for it's 20 hour service to have repaired, not willing to lose my weekends now.
See this video I took of my first WOT taken at the 2.1 hour engine time, note: no data for engine water temperature (bottom left bar graph)

Going from 6mph to 38mph in 9 seconds isn't too bad especially with full 50+ gallons of fuel and 6 people on board.
The troll feature is just that, put the throttle in forward gear idle, switch the 6YC over to the Troll and hit SET, this engages the feature, then arrow up to 1000 rpm it adjusts the rpm in very small increments, much more control compared to the actual throttle which can be touchy (I've made my first mate fall and my deck hand almost fall overboard - I do not advise playing with the DEC throttle if your first mate is walking around, wait for her to be comfortably seated!)
The Yamaha F300 is really impressive for it's smoothness, quite operation, and power. I don't care much for going over 45, but it can and did a little. Hole shot is very fun and will be easy to yank any wake board / skier up and out quick, but with the tritoon not producing much of a wake, the fun factor will be much less than a true ballast wake boat.
Our colors are admittingly a bit of a hodge podge, but it's all good we are happy: regatta blue with champagne accent and champagne canvas, ivory classic interior with napa beige stitched accent, full seagrass, raised helm...
Lake Murray looks like a great place to explore! I have a good friend in McCormick SC, not too far. I know your feeling, trust me the wait will be worth it, before you know it you and your family will love going out on the boat! One tip: make sure you know how to convert the swing back, I never asked, was never shown, so we spent a half hour on something so simple (lift and shove it port). And have them show you the radio, for the life of me something so simple as pressing source doesn't do what you think it will, you then have to rotate the volume knob, then press the knob to select the new source, another half hour gone, on the boat, so it's all good.
