I'm about to try a 3bld warp drive prop with HP hub direct drive on a generac 990 v-twin. its about the same power as the 084. I have used the 3 and 4bld ultra prop with good luck and most recent a 54" wood prop from Culver that split under pressure going into a hard wind in deep water. I'm just wondering if it's so heavy it will be sluggish or vibrate real bad.
