Check your PVS plugs in the prop, too big a hole and you can blow out or slip
The 24 Fury should be the prop. We have ran all kinds of props and sizes and this prop seems to be the best. Make sure you put enough plugs in the prop to help it out of the hole.
2016 z21 I run a A45 25 tempest that's worked have not found a better faster prop runs 70-71 loaded 2.75 bp same boat with 24 fury ran 67 at 3.25 bp
I know this is an old post. But my hole shot sucks and top speed so far has been 67. I'm not sure on prop to pad, but my 24 Fury has all plugs removed. Should I put the reducers in, then try, and try completely plugged off?Originally Posted by XWIRE
The PVS plugs only help holeshot, not top speed.
Need to measure Prop to Pad.
My hole isn't that good, and may be even a little slip. Motor only has 6 hours, so hoping it will wake up. In all fairness, was me, my son and my gf. All my tackle and 24 rods and reels, as well as water in both live wells and maybe 3/4 tank of fuel.

My Z21 with 2 people and gear, 2 8’ poles and 36 volt Ultrex ,3/4 tank gas goes to 4000 rpm and then right out of the hole with the 24 Fury and no plugs in the holes. It has to come out wide open throttle. Boat has a 12” manual jack plate raised about 1 1/2” and came from the factory set that way. Too many floating logs from the high water to get a top speed but have seen 71 on a short burst with 1 person. I got a 25 Tempest Plus spare that I want to try. My boat is a 2018 and came with a hole shot plate but I think it was for mounting transducer more than performance benefit.
Also has passenger console that I forgot to mention.

Mine has 2 poles, 4 batteries , ultrex 112. I'll have to measure, but my factory 12" slidemaster is a tad lower, like 3/4 to 1" down from the bottom, or level with the top. Zeke, raised 1 1/2"? Is that from stationary plate up 1 1/2"?
That is one loaded boat, 67 is good with 3 people, full wells and 3/4 fuel. I wouldnt expect a great holeshot under those conditions.
I made my own somewhat hole shot plate to mount my transducer yo, turned out really well. Was thinking of getting a 4 blade when loaded down like that. I still need to adjust my trim gauge, never had one on previous boats. Boat does porpoise a little at low speeds of trimmed up. So I still have some tweaking to do. Boat rides real well in the rough stuff. I came from a 19'7" bluewave purebay with an etec 135ho and a 4 blade. That boat had amazing hole shot.
My prop to pad is 4.5". I used my 78" level and leveled boat and motor. I got 4.5" from center of prop nut to top of level. Is that the correct way to measure?

Found that, do not have a slab, but used the level. I raised 1"
