@Functional hole shots are about torque and lift from the prop. HP isn't always the cure, though more is always better, lol. You might consider re-propping over re-powering to get a better hole shot. It's a ton less expensive. In my old Bullet, a 27 cupped 4-blade got me up on plane in less than three seconds at around 16-17 mph. A three blade polished and plugged 31 took what seemed a mile and forever to get on plane, but ran another 8 or mph faster at WOT trimmed out properly.
I realize this isn't totally related, but could be helpful.
