What prop for new setup?

[jeffswav]

Hey guys, I just want a little input on what props to try next year. As some of you know from other post I am raising the drive height from 8" to 5". The boat is a 236 Baja, 22deg hull, 500HP conservative, 70MPH. My best speed is with a 25 Mirage plus with double cup and lab finnish trimmed to the moon. I have about 10-11% prop slip and comes out of the hole very quickly. I have been told that the 3 blade prop will not work at 5". My first instinct is a Bravo 4 blade probably a 26 pitch. Has anyone tried anything else on this type of setup?

[Griff]

The current prop may still work. Probably just harder to get on plane. I would try it first. Other options would be a 24-26 Bravo 1 or REV4.

[bbladesprops]

Let us know if you want any 4 blade test propellers to test.

Thanks for the input. I think I will go ahead and try the Mirage and see what it does. I have several friends with varius props to try, just wanted to get a idea of what might work.

[jeffswav]

The Mirage prop worked fine at the 5" depth. Only 9.8% slip, 5200RPM, 74MPH.

I am kinda in your boat jeff. I am finally done and looking to see which prop i want to send to bblades. im gonna try my 25 mirage soon but i do like the B1 but i am told that with how deep my drive is in the water that it is not the best prop for my application.

Jeff, try a mach 4 blade if you can find one. I liked the mach the best on my 24' as did most of my buddies with 24 outlaws. The 4 blades are where it's at for handling and ride.

The 4 blades are where it's at for handling and ride.I guess you let yours go with the boat. I do not know anyone that uses a mach prop. The mirage is giving me very low slip numbers, I know a few guys with Bravo's that I can try. I am coming on plane very easy and I am not sure if a 4 blade prop would be faster.

[DAREDEVIL]

Most likeley a 3 blade prop has faster top speed then a 4 blade, but the over all handling and acceleration is better on a 4 blade.

[bajabob 718]

hay jeff any update:cheers2:

[jeffswav]

Have not tried any other props. Check out my Ram Air thread, I have some updates.

[blackhawk]

Have you tried a standard Mirage? It has less cup than a Plus and you get a couple hundred more rpm. My boat likes the Mirage much better but it slips a lot more in the mid-range. FAST prop though.

FAST prop though.My boat likes a lot of cup on the tips. I have twice the cup as a Mirage plus. The slip numbers are a lot higher with the standard Mirage.

Got ya. Every boat is different and my boat loves the Mirage at WFO. It actually slips less than the Mirage Plus(like 7%) but it definitely slips a lot more at cruise.

BTW, love the Ram-air post!!!

BTW, love the Ram-air post!!!Thanks, by the way it worked. Only about 1 or 2 MPH but that is huge for me.
I am trying a Hydromotive 4 blade 23p this weekend. I borrowed it from a freind I will let everyone know how it works.

Some people spend a lot of money on motor mods for 1-2 mph!

If the Hydro isn't an X it will need A LOT of trim to get bow lift. They lift the stern quite a bit and ride flat. Some boats really like them though.

That was with before I raised the x dim and with less HP. Back then it would not lift the bow enough to get any speed, it ran real flat. Well now with the raised x the boat runs flater and faster and I may not need the bow lift of the Mirage. Never know until you try it.

[blackhawk]

Yep! I NEVER pass up an opportunity to try a prop!

FYI - The best 4-blade I have tried to date is the Rev4. Just as fast as a Mirage Plus with great bow lift, awesome handling and a strong mid-range bite.

Need help have a 86 scarab panther 30 foot with 2 502 with trs drives....can't figure out what props will stop the engine from over revving?

[Donskihp]

Denny, need more info! What props are you running now? Brand and style, diameter and pitch? What speed are you running and whats your slippage?

86scarab panther with 2 502 with trs drives.. Need props that won't spin???

[Donskihp]

Denny, call Brett at bblades

[jeffswav]

OK, here are the results of the Hydro 23p. I could only pull it to 5300 RPM @70MPH, I could pull more RPM but it would loose speed. Prop slip was good at only 9%. Overall it felt good, it planed of better than the Mirage, but at least 2MPH slower given the heat. If I did a lot of skiing and tubing and made a lot of turns this prop would work. Probably a better prop for stepped hulls given that a lot of Fountains run these props. I may try a Bravo prop next just have to find the right timing to borrow one.

[Denny]

Denny, call Brett at bblades

Can you tell me how to contact Brett?

I have tried Mirage 23 and 25 both three blades.

I tried bravo 27 4 blades.

I tried bravo 32 4 blades.

I am running Mach 1 24 4 blades they seem to be the best.

I hit 4000 rpm and they spin....

bblades also has a test program you might want to inquire about. The test program worked pretty good for me.
