Looks like the Rev 4 only goes up to 25p. I'm running a 30p Bravo 1.

Hello Brett entering this discussion as you mentioned I might consider Rev 4s for my 35' Marlago center console twin 250EFI as one option. You should have received my 22P Bravo 1s now to lab for top speed and stern lift for this boat. How would you compare Rev 4 vs Bravo 1 for my application? Which prop would lab better for top speed and stern lift and get me in the 5200-5800 rpm range? As I told you I have a very light bow as well as no trouble planing. Thanks, Andy

The rev 4 is a very nice prop. I have a 34 cc fountain w twin 300 verados. Went from 3 blade to rev4 21p. 5k rpm picked up 8 plus mph. I have the gps/rpm pics to prove it. Fuel mileage went up 3/10s also. Never tried B1 on this boat.

As mentioned before, the Bravo 1 family responds the best to the Lab process as compared to the Revolution 4 family.
We'll be in touch with any questions.

Thank you,
Brett

You may be doing just fine as is. You really only have about 100 rpm to play with.
What pitch is the M+? You might be in a position to go up in pitch and have the propeller Lab Finished to gain top speed as well as cruise speed.

Brett

Brett,

The M+ is a 23p but it looks like the cupping was machined off. Low and mid are really doggy with the M+ and I don't spent a lot of time at WOT so top speed isn't a huge concern. Looking for the best low and mid range performance increase. Any ideas?

Thanks,
Josh

Moving t 4 blade props tends to improve both planning low end and cruise speeds as well as handling.
We have 4 blades for testing if you desire.

What info do you need to recommend a prop?

bbladesprops 06-22-2016 10:38 AM

bigvander,

It would make sense for you to call us and we can discuss your set up and options.
Please speak to Brad or myself. We are quite busy right now so we may need to call you back. This time of year the phones can get quite busy but you will always get a call back.

Brett

Can't find any info on how much rake the rev 4s and bravo 1s have.

Anybody??? Thanks

20 and 25 degrees.

Brett
