I ran the prop at several different engine heights and come to the conclusion the “sweet” spot is 3” below pad and about ¾ trim on my rig.

Hole shot information:
I tried it with no plugs and could not plane at all, put two mediums and one open, hole shot was acceptable but slight blow out at break over, went to 3 mediums and it was fantastic (especially for this rig). Spun to 4000 rpms and got on plane within 5 seconds with or without a partner. Better than any prop that has been on this boat, even rivals a worked Hydromotive, which was the best to date.

My overall evaluation of the CroxProp: a beefy heavy bladed prop built to take abuse, seems a little stiffer than some 26”er’s, a superb hole shot wheel, good top end, great load carrying capabilities and a very efficient prop. Guarantee this prop along with a 27”er will be looking back at 80 mph with heavy tournament load as soon as this weather cools about 30 degrees.

CroxProp results: I (by myself, 250 lbs, no partner) made 12; 4 mile runs with a 6 mph tail wind one-way. Average speed of the 12 runs …. 77.82 mph @ 5900 rpms, prop slip is about 8%. Top speed was 78.70 mph.

CroxProp results: Partner and I (450lbs) made 8 runs. Average speed 75.92 mph @ 5800 rpms, prop slip 9%. Top speed 76.46 mph.

For comparison, I also ran a 27 Fury and a 27 Tempest + under same situations, adding fuel to keep everything as equal as possible.

27 Fury results (by myself, 250 lbs, no partner). Average 78.05 mph @ 5800, prop slip 10%. Top 79.02 mph.
27 Fury results (partner and I (450lbs). Average 75.51 @ 5700 rpms, prop slip 11%. Top speed 76.79 mph.
Hole shot acceptable with Fury about 6 seconds. The Fury ran best at 3 3/8” below pad.

27 Tempest+ results (by myself, 250 lbs, no partner). Average 77.42 mph @ 5900 rpm, prop slip 12%. Top speed 77.91 mph.
27 Tempest+ results (partner and I , 450lbs). Average 75.55 mph @ 5800, prop slip 13%. Top speed 76.39 mph. Hole shot fair (worst of all) 7seconds +. Tempest ran best at 3” below pad.

Top speed w/o partner on the Fury and Croxton were virtually same, but of course the CroxProp is a 26" and the others are 27's so a 27 Crox may be a bit faster on top. I figure if I had a 27 Croxton and turned it to 5800 with 8 - 9% slip it would be 80.

The CroxProp was by far the best holeshot prop of the bunch, in a class of it's own, the only prop I have tried that has even come close is a worked B&B 27 Hydromotive w/8 pvs holes.

I was very pleased with the load carrying capabilities of the CroxProp, I carry a heavy load and 90% of my time have a partner. This was the best by far of the 3 props. I lost less than 2 miles per hour when my partner climbed in w/ the Croxton, and lost 3.5 mph with the fury, and over 2 mph with the Tempest.

Once again not really comparing apples to apples, a 26" & 2 - 27"ers. But this is all I had and just posted for information only.

Yup, I wish it was a 27" for a true comparison. But from the knowledge I gained through the testing, I suspect that that a stock 27" CroxProp will be about 2 mph or so faster than the Fury and Tempest. The holeshot was impressive. My guess is it will rival a B&Bed worked prop, especially if you need lift, but it will be stock. It is a very efficient prop.

I feel like when comparing prop to prop it is more important to look at the RPM range the props run in rather than the stamped pitch because companies measure pitch different. Looking at the RPM range of the three props you ran I would say that you are comparing apples to apples. The 26 CroxProp turned 5900 RPM by yourself in the summer heat. I would think that is as close to perfect as you can get your motor. A 1" pitch difference normally results in a 200 RPM drop. If it had been a 27 with your partner you would only be turning 5600 RPM in the heat, and I feel like your speed would suffer.

You also say that the Fury lost 3.5 mph with your partner, your numbers show by yourself the Fury ran 78.05 (average) with your partner 75.51 (average) for a difference of 2.54 mph. As far as the Fury loosing more speed with your partner it did loose a little more, but the difference in the CroxProp and the Fury with your partner is only 0.41 mph. The Fury was 0.23 mph faster by yourself than the CroxProp. So I would say the 26 CroxProp and a 27 Fury are about as close overall as two props can be on a boat.

I am by no means trying to put down the CroxProp or your test results. I am just trying to show the numbers as they are. I would love to run the 26 CroxProp on my boat to compare it to my 27 Fury and 28 Quad IV X-OB Hydromotive, these two props are as close on my boat as the CroxProp and the Fury were on your boat.

Yep, they are close very close, but the holeshot with the CroxProp is miles apart. 0-30 in about 5 sec, w/partner and no JP manipulation is fantastic, especially on this rig. 2-3 sec better than the Fury.

These new 250 etecs are hard to prop just look at some of the post's on here about it. Most folks are giving up one to get the other, holeshot or top end.

The CroxProp is the best of both worlds on my rig. The holeshot of a worked $800 Hydromotive along with a great top end.
As long as the CroxProp is reasonably priced I believe Mark has a winner, is it the prop to end all props, no that will never happen.
We will always want a 1 second holeshot and that theoretical top speed.

If Mark would hurry up and get his prop on the market I would buy one and then I may not need to worry with these other props.

Hurry up Mark we are waiting

awesome numbers.
