Hey, didnt know you were so close to me in Arkansas. Dont know if any help, but Im running a 24 Tempest on a 95 175 EFI. The torque will be different on a newer model 150 EFI as BC stated.Im thinking a Fury might be better. BC will know a better idea than a dealer, I believe, because there arent many Eyras around for a dealer to check out.BTW, 52 gal of gas? Where are you running?96 Eyra/12 Mercury 175 Pro XS with 2015 single axle trailer2017 Victory Gunner
