I've done some searching on floscan and the like, but most of the posts seem a little older and some of the suggested alternatives are discontinued. I was wondering if anyone has had experience with anything new out there that does the same. Some of your new boats already have similar GPH gauges and such, so I kinda wanted to jump on that band wagon. I'd like to see what I use GPH in real time so I can trim the boat out better for better GPH. I may want to upgrade my chart plotter...are there any systems out there that incorporate this technology instead of purchasing a standalone $600 floscan? I have carb, twin Mercruiser 5.7.
