BCB might have been the fastest at one time but I doubt it now. I have a 2015 Phoenix 919 with a 225 Mercury that will bust 80mph on a 98deg day. I run it every week at 76/77mph with 2 250lb guys in it. Not to mention it's the smoothest riding boat I've ever been in.
What do you throw next
2015 Phoenix 919 PRO XP
2015 Mercury Pro XS 225
Lowrance HDS Touch 9 and Touch 7
