prop selection
I got the motor back in my 24 in time to run it Quite a bit saturday. it ran and sounded great! The mid-range was an
Extremely noticable increase, I ran it with a 25 tempest plus
prop , and it consistantly ran 68 on GPS but I couldn't turn it but 4350-4400 rpm. The boat likes to run alot of trim when running it hard, it rooster tails pretty good, I would imagine
the X is a little low. I am thinking about trying a 23 mirage.
Would any of you experianced Pantera experts like to give a recomendation. Mirage , mirage plus , bravo , Hydro-motive
ect. The motor should be making 450-475 hp. I posted a pic.
because I know we all love pictures for some reason. Thanks Guys!!!!!!

Re: prop selection
Did you dyno the motor? and know where peak HP is?
I'm running 560hp @ 5800, but spinning a 23P Mir+ at 5500-5600rpm @ 75mph.
I'm gonna try a 22 B1 to get more rpms, plus I want to run a 4 blade.
I hope to keep my top end, get a little better cruise and more all round stability.
You should prop the boat to run at peak HP.

Re: prop selection
littldcsrodshop, How do you plan to use the boat mostly.? 2 adults or 4 or more mostl times? Rough water or calm with cruiser wakes? Any waterskiing or tubing? or just looking for the max top end? Are you using the TRS drive? I have tried many props and Bravo and TRS drives, There are many variables to consider. In general though I like the 3 blades on the TRS drive, to get similar top speeds with the 4 blade bravo1 it needs to be labbed in comparison to the stock Mirage or Hydro 3 blades. My personal favorite prop for that power range was the Hydromotive 3 Blade 24 pitch The 15.5 diameter really worked well on my boat I just outgrew it when I added power.

Re: prop selection
Usually 2 adults & small children. No tubing or anything, as far as water conditions goes it is usually calm with occasional chop & cruiser wakes. My holeshot is excellant now so that is
not an issue. When I run the boat hard I am usually by myself.
How do the 15.5's react as compaired to the mirages,same pitch ect ? I think I would like the midrange of a 4 blade but I don't really want to sacrafice any top end speed. (just like
everyone else)

Re: prop selection
Last year with the TRS drive I found the labbed bravo1 26 to run the same speeds as the stock mirage+25 at 3000rpm and 5200rpm so that cruise speed was identical. 3000rpms was 40.5mph with both props. The boat felt lighter with the mirage and more stable with the Bravo1. I think that you will probably like the mirage+ in a 23 pitch or the standard mirage which will give a few more rpm's
