You also will want to find the service bulletin for ventilating the prop it will help with the holeshot.
Ventilating/porting is a deliberate effort to get the rpms of the engine up at a faster rate with a high pitched prop by allowing exhaust gasses to flow across the blades which reduce the density of the water, reducing the load on the engine. It also allows you to pop up a slalom skier with a higher pitched prop so you don't need 2 props for normal running and playing with toys.
Getting the rpms up gets the horsepower up faster which gets you out of the hole faster and 2 stroke engines love to run, not lug. Once on top, when the drag between the boat hull and the water are reduced at higher speeds, it allows you to get the benefit of the higher pitch for more mph.....as long as you have enough hp to keep the rpms (for my engines) at the top of the rpm recommended range or a bit higher.
It's here in the archives and being there you can probably google the question as it was an OMC prop where the notice was applied. I used it to get the idea for porting my Ballistic 13 ? x 24XL I only drilled a 5/16 hole and on this prop that was plenty. The idea on porting is to get about 1000 rpm enhancement when firewalling the throttle in the hole and having a 3-5 second shot. Immediately after the prop should lock up and the rpms should drop back to where they would be had you not ported (all 3 blades identically where shown in my picture). If the holes are too small no effect. If too large the engine will rev too high and the boat will be sluggish in the hole with the engine revving much higher than 1000 give or take. So start small (5/16) and enlarge 1/16" till you get your sweet spot.
You can read about porting if you go to the Boating parts and accessories, props, and look around there for the instruction tutorial....tells you all about props and what kind of performance you can get from what.
The prop shown was not from the OMC I mentioned above. It was used on a stock 90 hp Merc I used on a 17 ? alum boat running right at 50 and 5700 +/- rpm, engine cowl and wake in my Avatar.
