Hey Peeps, my 2010 Puma has the smartcraft tach and speedo, which both have the troll and +/- buttons. Is it possible to make this work (with an add on or something) on a Pro XS 250 or is it a 4 stroke only thing. Not that I need to troll a lot or anything just wondering.Thanks to any and all responses Sent from my SAMSUNG-SM-G891A using Tapatalk
