    How far below the bottom is your prop shaft?

    The prop shaft on my 22 Donzi is really deep at like 7" below.
    On my 24 Super it was about 5" below but that was a straight V not a round bottom.

    I know guys with 24 X 7s that run the prop shaft at 3" below but need 4 or 5 blade props.

    My guess is that a Mirage Plus would work on a round bottom Donzi with the prop shaft at 5" below and maybe as high as 4" below. Give one a try; what have you got to loose
    Thank you, Patrick

    For what it's worth, Catch22 (Jim Collins) ran a 31" Hydro Q4 and could hit 94 on most days.

    I do have something to lose because I would have to pay a fee to try one. I've been running a BBlades labbed 30p Bravo One. It works great on my boat. No bad handling characteristics at all. I'm just wondering if a Mirage plus will get the boat on plane. If it will then all indications are that I will pick up 2-3 mph and still have a good handling boat. It seems that everyone I know with a shorty is running a four blade. The batteries are out of my boat now so I can't lower my drive to measure but I think I'm 4-5 inches below the bottom.

    Yes, It will cost you $30-40 to try one

    Come on Carl, surely you'd spend the $25 or even $50 fee plus shipping to BBlades to try a 29p Mirage plus. Like tires on a car, increased performance from a prop is the best bang for the $$...

    My 24' Superboat handled better in the rough with the BBlades labbed B1 but I did run the labbed M+ on calm day when doing speed runs...

    Nice to have options and since no one seems to want to buy my 25p Mirage, I'll likely be sending that out to be labbed for top speed run in my Donzi...
    Thank you, Patrick

    I'll discuss it with Brett and maybe start a new thread about it. If everyone says it won't get the boat on plane then I'd just be throwing away $$ trying one. And yes, I'd have to drop to a 29 or maybe even a 28 pitch.

    Glad you are sticking with Ford power and the King Cobra. While it has been many years since I had my 1988 Testarossa with a 460 and King Cobra it was the only reason I bought it in the first place. If my memory is correct the stock prop was a 3 blade 14 1/2x 24 Raker. Good luck and enjoy! Brian

    I'm starting with a 29p mirage plus.

    The dash is finally done. I designed my own dash, wrote the code, and laser cut the piece out. (Let me know if someone wants one)

    The engine is in and I have test run it. But have not taken the boat out on the water yet. I can't wait. Saturday should be the day!

    I run a Mirage+ and my drive is up 1.5". It works fine on mine but you have to walk it up or it'll blow out.

    22classic, The boat looks great. You must be up in N. California? Your original post, second picture, looks like the South West. Just wondering, I'm in N. AZ.

    Yes I'm in Nor Cal, the boat usually lives on the west shore of Tahoe, but does make a random delta and Santa Cruz trip. (I live in San Jose)

    The CC system is a San Juan that I bought from a buddy. So far it works great. But getting all the hoses and lines hooked up can be a bit of a pain and ugly. Maybe in the future I will clean it up, but we'll see what kind of time I have.

    Ill post a video of it running next, and some better shots of the dash.
