    Default Hering in a bravo application?

    I just picked up a 25 daytona with a 625 ilmor/Bravo/Imco lower/28p b1 prop. Anyone have a 5 blade Hering on their small cat? I think the cost is around $2200.

    I'm looking for good high rpm cruise speed and good top end numbers.

    Actually, they are 1700. I think the guys name at Herring in HB is Jeff. I am on his email list and he does periodic demo testing at Elsinore for those that want to try Herring props. They are some of the best wheels in the industry and seem very professional to deal with. If you try one out and it is not right, I am pretty sure they will let you trade it in for another one.

    That sounds more like you are buying it with an exchange.

    I don't believe so, You may be thinking of the race cleavers which are more expensive. Their 5 blade bravo props are 1700 last time I spoke with them.

    Hey Cliff,
    Call DCB and ask for Tony. He did all the test work for Eliminator when he worked there. He will give you the optimum set up for your combination. He helped me quite a bit.
    How does that thing run?

    IMO it runs great! 88-90mph full load (5 adults), I need to go out by myself and see what it will do. All around performance is awesome though.

    You need to look at all variables such as mid range cruising speed. Typically, you do a lot of boating in the 4000rpm range. 5 blade props will usually give you better mid range speeds at the same RPM as a 4 blade. I run 60mph at 4000rpm with a 29" 5 blade and only 52mph with a 30" 4 blade at 4000rpm. Better speed and fuel economy also.

    8 more mph at at the same rpm is awesome.

    5 Blade is awesome! Just bought a 6 blade Hydromotive to try next. My "X" is pretty high though. Lower cruise rpm, higher top speed, BUT harder on the drive, if its marginal now, you will know it real soon. Make sure you've got a good, aftermarket prop shaft in there, or when it breaks, it and the prop will be at the bottom of the lake. TIMINATOR

    You are right about being harder on the drive but it really comes down to how you operate your boat. No hard starts, keep it around 3500 till it planes out and don't cruise for long periods in the RPM range where your motor makes its peak torque. If the boat gets out of the water, gotta back off the throttle before it lands and that prop bites again. 6 blades is really gonna hook up. They are typically used in race application where you need low single digit slip performance. Cat hulls are fine with 12-13% slip for basic performance boating on the lake.

    I'm spinning 4 blade herring cleavers and Like it. We tried the 5 blade which gave great cruise but gave a bit too much stern lift at higher speeds which made us feel loose. Wish they would have worked as it was about 8 mph better cruise.

    Is 12-13% pretty decent for Bravo stuff? I'm between 7-8% on my ssm stuff and Predator is lower than that, by a bunch! It's crazy to see it on the Livorsi gauge when Im co-driving with him. We run 5 Axis props on Predator.........

    Come to think of it, my 36 Spectre with Bravos was 10-11% slip.
