Strait hull props
 

Anyone running a set of Herring props on a strait hull gun?

Bravo version, no boxes and full cabin. Wondering what gains in performance and handling are to be gained.

Fred, we run 16X25 4 blades on the 3a's on our Gun. Little baby cleavers :D

Hey, I need some of those plastic shaft covers. You got any?

Sorry to hijack your thread VB. I have some new/in the box 4 blade Merc 26 pitch bravo props for 700.00 if you want 'em :drink:

It's OK, keeps it near the top!

Were on the limiters with stock 28's so the 26's won't help unless we switch ratio's, which we may do.

Thanks

Re: Strait hull props
 

Well, let me know.


Fred, I'll get an order in for 'em.

Von--check with Gordo. He had a bunch of props on MWBP in the prop section of the forum.

Thanks Griff, we already ran a set of his but they were labed and repitched to 29's so we saw about a 1 mph gain but we were back on revlimiter.

We're going to bump the HP to the mid 700's, maybe close to 800 and do some testing. Want to run it in the shootout next year just for grins so I am looking for a set of props for that. We are able to go back to 650 real easy so it will be set to mild except for the test time and then for the few days in August.

I know the feeling, bub.
I'm doing a little research of my own on engine changes for the same reason.
I've got SSM3A drives, and with the price of those propellers being as high as they are I can spend a ton of money on engine stuff and still be ahead.

Re: Strait hull props
 

In that case, Check with Hell Ya. He might still have his maximus 5 blades from his scarab. I think they were in the 30-32" range.

Re: Strait hull props
 

How many lbs of boost are you running now at 650? How much more will you need to be at 800. I would like to try this :D I'm running 509ci 250ci blower 5lbs boost 30 bravo with boxes straight bottom TG 82 mph on GPS. I think My HP is 650. What is your set up?

Re: Strait hull props
 

I have a pair of Bravo 1 Lab 30's you would be welcome to try.
Give me a call 573-280-9259

Thanks Dennis, I'll give you a holler when we get to that time. I've been wanting to try a set of labed 30's.

On the surface about the same. Engines are 509's with 250's and 5 lbs of boost, no boxes and running 28 B 1's no boxes.

Pulled out the dyno sheets this morning and the engines make 653 & 660 at 5200. We are changing the ignition and bumping the rev limiter and that alone gets us to 680 & 690 at 5500.

As for boost, I am not sure yet but I will let you know when I know. Right now the upper pully is 4.1" and the lower is 6.4" We also are going to mess with some drive heights so this should all be interesing.

Re: Strait hull props
 

What type of ignition are you going with? If you change the upper pulley to increase the boost would you need to rejet the carb? I will be looking forward to hearing more, Thanks

Re: Strait hull props
 

Seahawk, I would not try this running bravos. You're asking for drive failure. Your boat is running and looking great! I would hate to see you get frustrated with drives breaking.

Re: Strait hull props
 

Yea, I'd second that for full time use, remember we are going for a 5 day set up then back to "stock".

After seeing Dennis run 2 years ago, we have to give it a run :evilb:

Re: Strait hull props
 

I was just thinking that if it is as easy as changing a pulley and a prop I could have some fun with it. I agree with keeping it the way it is. I just came back from the drag races and wow, talk about horse power. I guess after that the boat seems slow :eek: :evilb: :eek:
