27 Fever prop question.
 

I've had new 496 CMI headers tacked onto the stock motor this winter. She's a 2004 27 fever with a Bravo 1. Any recommendations on the new prop?

I'm turning a 23P labbed Hydro 4 blade with a similar set up. Check with Brett at BBlades, he can dial you in with exactly what you need. He'll probalbly set you up with a 24 Bravo One.

My setup is exactly the same: 496HO and CMI sport tubes.
The only slight difference is that I have Bravo XR (19" X dimension), which possibly absorbs a bit more than standard Bravo.
Anyway, I'm hitting a straight 70 with a 4 blades 26" L/H Bravo prop, at 5100 RPM.
I did talk to Brett, he confirmed that's just about all I can expect in top speed with this setup.
He suggested that a 5 blades Maximus should improve acceleration without hurting too much on top speed, but I didn't give that a try (yet).

Had a 1998 with 502 mpi, 415 HP I used a 24 Hydro I think 5100rpms and hit 71 was the best I could get.

26" Bravo 1 should be your prop.

I think you might have a 1.65 drive ratio ? If so a labbed 30 bravo would be about right . I have the same set up minus the headers and am running 69.5 gps stock 28 b1 lefty .. I bought a 30 lab but it is a little slow out of the hole .. I am happy with the 28 .. been thinking about a maximus or 5 blade hydro p5x ..

28p LH, depending on the water... I get 67-70 but some crazy list to the left when getting on plane...But I dont have CMI's so you might see better?

With a LH prop? Now that's weird!

Some 27's came with RH set up, I also had a 2001 27 Fever w/500efi 5400rpms came with a 25 Hydro RH gps 74-76 all day, speedo would hit 78-80. AND IT LISTED TO THE LEFT LIKE A BI%^* :evilb:

I understand that, with a RH prop.
But 10K4U says he's spinning a LH prop. With it, if any kind of listing should be expected, that's to stbd!

Thanks for the input. On a side note, I had a 4 blade SS Bravo 28P on it, pre-header, and was constantly hitting the rev-limiter so I think a bid more prop is required.

Where's the rev limit set?

You are correct, LH prop should not be listing to the left, unless their is something else very wrong going on:evilb:

Didn't set it myself but the alarm goes off around 4900-5000 rpm's.

If the motor will pull past that, you might look into getting that changed before you buy a new prop.

Haha your right ,just realized I typed the opposite of what I meant.It list towards the driver(right), dont notice it much when Im by myself but with 3 or so other people riding I really can notice it.Either way it seems to work a little better all around using the LH in my situation.
