Brother law has had 2 Lund Impacts both 1875s first one had a yammy 115 second one a has a 115 merc 4 stroke both would go 40ish with two guys. I used to pull 3 tubes loaded with kids behind my Lund 1700 fisherman with a 140 Zuk pretty similar to a 115 power wise. Not a lot of Trackers up here so can't tell ya if there better then or worse then a Lund,but there's a buzzillion deep v Lund's,Alumacrafts,and Crestliners.
