Paging Prop Experts . . .
 

Now that I'm finally running what I consider the best prop for my boat tested to date, I have a few questions.

I'm running a 28P Bravo 1 on my 24' Pantera with 650HP. Total weight approximately 4600#. I will get better performance numbers as I just received my GPS, but currently I am running about 85 MPH (Speedo) @ 4800 RPM.

1. Does this speed/RPM seem right?

2. What can I do to get my RPM's up without sacrificing low/mid range performance?

3. I'm be interested in Lab finishing prices, please quote finishing my prop and also a new Bravo 1 finished from you shipped to Hillside, IL 60162. (See Jeff, I'm not cheap or poor!!)

Thanks,

Kirk

He's your best bet on this subject

What gearing in the drive?????

With a 1.5 drive a 28 @ 4800 going 85mph has a 0% slip ratio. With 10% slip which is fairly good for V's, its 77mph.

You would pick up 400 or so rpms by dropping to a 26 Bravo. Labbing the 28 would probably give you 200-300 rpms.

I must be real efficient with 0% slip huh Griff!!!??

Like I said, I'll get true GPS reading this week to see what I'm really doing.

My GPS Lies
 

O.K. I have to tell the sad truth. My GPS Lies!!!!!

I am actually running 78 MPH at 4650 RPM with the Bravo 1 28P. I am very disappointed. I called Darrin at Houston Prop and he recommends a 26 increased to a 27 with some cuppping and lab finishing. I'm going to go with his recommendation, but need to purchase my drive first.

What numbers should I anticipate with a 27P at 5000 - 5100 RPM?

sell the gps that is what i should do..
sell gps = positive cash flow
every time i use my gps = cubik negative cashflow-

Dumbest thing I've done buying that damn GPS. My speedo was wonderful until that GPS showed up!!!!
