Help from the experts, or the one's runnin them
Fellas new here, looking for some knowledge from those who know Props, and step hulls. I am going to add a link to Q&A Posted on OSO. I could really use some conformation or other advice. Appreciate all the help.
2000 ZX with the 377's. I have a set of 3bl 25p lab mirage boat runs 72 gps 5000 rpm.
Also have a set of 4bl 26p lab Bravo I 74 gps 5000 rpm.
What am I doing wrong? Thought this should be an 82 mph boat with the twin step hull? Fuel levels were approx half. 1-4 persons did not matter.
2nd question. I have been getting a lot of cavitation when getting to plane. I have backed up on the K planes and has since helped. Thanks for any and all help.

I personally think if you have to run a labbed prop to get that extra 1 to 3 mph your wasting money. I believe trueser tried some other props at cumberland that handled better. Since i sell and test props as most know, i can tell you this. You need to try other props. Every labbing guy will tell you his are the best. I have an 86 mph 22 and can say that the only labbed props i have on my boat were labbed merc racing and two throttle up props( not their cnc ) and my stock out of the box precision props were at least 2 mph faster. I don't labb props and won't, it isn't worth it to me. Ask trueser for his opinion, he isn't capable of lying about his boat. He likes me and will tell me to stick it if he doesn't believe me. One thing there is more to a boat then just speed, it id called handling.
Nice to see someone nows what there talking about
I agree since I own one that does 80+ at 5100 with lab 27 mirages

Mr. X also knows this boat well. I think he broke the 80 mark in his. I seem to remember he did the SM exhaust on his scorps.
Hey there how did you make out with this
I own a 28zx with 377 stock with headers turning the props inward with 27 mirage labs at 5100 82 mph on gps . Question Im interested in trying some bravo's 4 blade I m guessing 26 pitch anyone try these and do you think I would gain or loose anything

great article love those SBC
I would love to chat with you if you could get back to me. New on here just bought a 28' Scorpion zx with 27 mirages labbed . I am experiencing the same issues at around 76 to 80 with chine my props spin in . Any suggestions on if the 4 blade bravos would work and how fast do you think I would go with 4 blades . Does the boat handle better spinning out and how much speed would I sacrifice. What I m looking for is max speed with safe ride . I would be happy if I could maintain 80 with stability . Any way of finding out or suggestions on where to find out if any combination works better than the current one I have. Thanks

So far I have hit 79.5 on GPS. One of these days when I don’t have my wife on board I will break the 80 MPH. The rev limiters are set @ 5200-5250. I'm running the 25 mirage plus. Ted’s old boat that is owned by my friend hit 82-84 on GPS. The boat really loves trim above 7 on the indicator. But it also loves to chine walk. I have a pair of 26 Plus but have not tried them yet. The other problem I hate is getting on plane in ruff water. The props blow out way too easy. I just hit 300 hours and they are still running strong. Griz hit the nail on the head. I would rather have the handling than the speed. The 4 blades I tried got on plane in a heart beat. I could stay on plane @ 1500 RPM. But my top speed was only 71mph. I can always throw the three blades on too whoop Roadtrip. I would also like to swap the props around and see the difference in speed, handling and getting on plane in choppy water.
The other thing that has limited my speed is my busted up hand. It's finally getting to a point where I can trust it to hold the steering wheel.
I destroyed a pair of Checkmate's with big block twins. After 10 miles of running we finally stopped and I had to lift my hatch to show that I only had small block Scorpion stock motors. And one of the guys was really pissed that he burned up all his fuel.
Go easy on the Scorpion comments.
PM me and we can talk. I have a few questions on Bravo 1's
Where and when did you get this?
