Sea Giraffe here,
I haven't run it out with the raised X. Yours will do 73 or so with ease. How's the engine progress?
Just hung out with Jack Stuteville today, he remembers Your 28 race boat when he worked for Vincenzo.
You'll have to stop by next time you're in Florida.

Something's a bit of a stretch here......?

Mario, Jeff, Bill & I were in Florida @ the Dora boat show with Bill's new F-14 Donzi & we just got back. Bill had the only computer so Jeff & I had to sign in under Bill's name, we had a great time & even went to Magnum. Mark

Lee,
I wish I could tell you!! My GPS speed and RPMs don't make sense with prop pitch when run through a calculator with Volvo ratios.
I bought my props from Grizzly, last set he sold that we're a matched L&R turning set. These are Solas props he had made for the old Volvo drives working with Solas and using Donzi Classics. Unfortunately the boxes are labeled differently than the props and my emails with him are different from that.
I want to trust my tachs, and the GPS........

mmmmmmm . .. .
Jeff,
What is your power?
My boat has two 465 HP 377 Cu In with Volvo 280 drives and nose cones, raised 2" on 29.5" centers, I run two of Grizzly's last Solas props, spinning out 15.5" x 21 and run 77 mph at 4400 RPM in glass smooth flat water . . Sadly I can't tell you if this was WOT as I wasn't paying attention to throttle position . . DOH!

Calling the Sea Giraffe, come on in hallj what speed does your 27 sport pull with your engine build with the Volvo 280 drives and ?? props.
My 27 is on Bravo 1's with 383ci motors and 14.25" x 26" props but we have not been able to run it at any speed yet so what will be your guess ?

Have you run your boat yet? Curious how this size of prop works for you as our power set up are similar, although the drives are radically different. Your props are likely 12" further behind your boat . .
I'm starting to think that my 15 5/8" OD props are to large in diameter and that a smaller prop will run better. I can't trust the labeling of the props
my offhand uneducated guess is that your pitch is to high . . ?

I'd like to take this thread back to nose cones . ..
Jeff, your boat is stock and you gained 400 rpm w/o cones . . .
I'm curious if nose cones may become effective at a higher speed .? . . does anyone know of a stock Volvo drive boat that runs well over 70 MPH ?. . mine has 280 drives with nose cones. I've run over 70 . . . but am very concerned about a nose cone failure . . . not certain I want to experience something failing at speed . . .
