Cleaver labbing
 

I have a stock merc prop (kinda thick) that`s a pitch or two too large . 18x31 R15
The cruise is great 70mph at 3900 but I would like less engine load at cruise , Thats about 3-4# of boost versus 1-2# with a 18x29 R18
If labbed how much cruise speed should I expect to lose?

usually labbing will increase cruise/efficiency. Why not use the 29's and get them labbed? What's the difference in speed/rpm between the 2 sets of props?

The 31s are mine .
The 29`s are borrowed , owner deciding if he will sell them to me.
The speed at 4000k rpm is 10mph , it`s a big difference.

After your disastrous interaction about the story on Stu Jones, I can't believe you are at it again so soon.

I don`t even know how to aswer that and honestly I don`t whats wrong with you .. you certainly have a different way of thinking and that`s being nice.
There was nothing "disasterous" about it. I voiced my opionion end of story.
You constatly post the dumbest questions and in the wrong forum and you think you`re going to talk $hit to me?
Like Elon told Disney CEO ... GO .. you know the rest .. weirdo

What HP rating are you props? I would think your boat likes the 18 rake more than the 15 as well, no?

100% right, it loves more rake. I`d love to try a 20* rake.
I spoke to Cutting edge, he could get me some more rpm in the midrange, I would lose some speed but also run less boost and the props would be thinner .. hmm . I got some decisions to make.

The cruise is with 31 pitch is really nice .... 4000k rpm and 3.5# of boost.

Have you talked to Brett at BBlades? Yes, hard to get a hold of some times but he knows his stuff.

And they have their winter deal coming up, which is nice

Have you talked to FJ Midwest? LOTO prop maker/shop. I use Cool Breeze, but I am running B1's. George at Cool Breeze can do anything, I am just not knowledgeable of his cleaver style magic.

I second FJ Midwest at the lake too. I've had work done by them. You can drive over there in 10 minutes, take your props with you and talk through what you are looking for. They will spend all the time needed talking through it with you. They do really nice work. And they race! Nice option for you now that you own property at the lake.

B1s I had labbed, balanced etc at FJ.

FJ in LOTO has done work for me ... They are very good . I finally reach him till a week ago .
Instead messing with the props I have it would make more sense to just get the props I and the boat wants.
Boat likes Rake so I wanna give it more rake.

The Checkmate wanted more rake as well and I ordered props with 21 degrees and the boat responded as expected.

MentalPause,

If you don't mind me asking, What was the bill on those B1s you had labbed and what all did they do? You can PM me if that's more appropriate.

Thanks. Brad.

Hey Bill,
If picked up 5mph going from 15R to 18rake , I was also thinking 20R would be the ticket.
