Ok, moving right along in 2018......... The Rev 4 was very impressive when tested in 2017 for being very quick to plane, great cruise prop as well. Never did get around to a W.O.T. test in 2017, I'll run that number this year if and when spring ever gets here. Also have a labbed Merc Maximus 24P to try this year. Going from a Bravo 1/26P to a Maximus 24P w/a bigger diameter and the extra blade sounds about right for propping.
