Unless you add more power you will get either more top speed or better hole shot not both at the same time

What prop and pictures currently on your boat and what is the wide-open throttle RPM You can go down and pitch were at a four blade and get better whole shot but both of those will cause you to lose TopSpeed so you end up Compromising on what is the most beneficial youth
 
If, with the current prop, your engine revs up at wide open throttle to within the specified max wide open throttle rpm range, with your "normal" load, 3/4 full gas tank and good tune, calm sea and light wind, you have the correct prop. Per Dieter's post, from that point you only loose top end to gain acceleration. The only "bolt on" solution is a bigger engine. Typically a bigger carb on you existing engine will only make a minor difference. Boats, especially Deep Vs, are HP hogs.
