Surfrat57, I sold my 17 puma and got a 2021 eyra, I would think the 25/4 fury would do alright on the new v8 but a 24 pitch may be better. I just got a 26 bravo xs for mine, and its running 75.2 @5990 the hole shot improved over my 24/3 fury. For some reason extremely loaded it still doesnt hole shot the best (this may be more of the eyra hull as its not known for as good of a hole shot at the others) I will probably send it for a bit of work and get some cup added. I did try a 25p bravo xs and I was on the limiter at 70. Lots of guys are staying away from the fury 4’s as they are known for slinging blades.. I’ve owned 4 and never lost an ear.. I also think your either a 4 blade guy or your not and I dont have to have all that top speed. The new v8 is impressive, Im doing my first oil change at 20 hours tomorrow. It was about $100 in parts. So long DFI oil… lol No telling what I was spending a year on that hundreds of dollars I’m sure.
As for the graph options I had lowrance and their menus are pretty complex. I went with all garmin stuff and its pretty simple in operation. Might be worth a look. I really enjoy my live scope. I would match your graphs and trolling motor to whatever brand you end up going with.
