Hopefully you'll be able to make it out. It's nice to meet the people I talk with on here... You know what "SHOWTIME" looks like. More than likely we'll be on the outside unless I can sneak in early one AM.

Mac, I ran the 23P Mirage and was able to get 42 MPH @ 4400 rpm's, not very impressive. I'm going to start experimenting with different props. I found a prop shop over in Daytona Beach. I talked with the owner and they have a prop test program to try before you buy. I may wind up going to a four blade prop. Don't know yet...

I bet a big heavy single like that 260 will end up benefitting from a 4-blade. I'm rethinking my prop as well right now. Are you breaking in the motor over 5hrs? 10? And then what's your target rpm? I really believe you'll knock the door on 50 when you're dialed in. Keep it up! Yours looks better than mine, so that should cheer you up

Hey mac. Yea I'd like to see 50 mph. At this time with the props I have the best so far is 42 mph @4400 rpm's. I'm hoping with the right prop I'll get closer to my goal. The 454/330 should run 4800 rpm's at WOT...

I thought my 454/330 was stamped 4400-4600 now I gotta go look again 
That bravo sucks more HP than my alpha does, but you don't have to worry about it blowing to shreds every time you are getting on plane... If I remember you have a 1.5r Bravo right? So that puts your slip #'s at 28% if you are spinning a 21P @ 4400rpm and getting 42mph. You will have 50mph if you can get your slip #'s in the 17-19% range with a 21P spinning 4600rpm which is what I'm guessing your motor will spin with a 4-blade on it. You know this already, but call Brett @ BBlades, and hit the swap shop! You're going to get there!

mac, the stock 454/330 is 4400-4600 rpm's. I believe mine will be a little higher due to being a complete roller motor. I'm running 42 mph @ 4400 rpms with a 23 Mirage on a 1.5 Bravo 1.

Today I started to mount the original/refurbished 1982 teak swim platform. Of course as soon as I had all the holes drilled it started to pour down rain, remnants of Hurricane Isaac. I'll have to finish up Thursday cause I'll be at the FD tomorrow on a 24 hour shift.

I don't know if this helps or not, but I have a 87 260 stinger which I repowered with a 496 MAG HO (425hp) with a bravo 1 X drive. I'm turning a 22 P 4 blade hydomotive prop and at 4800 rpm speed on gps is about 58mph. My old 454/330 with alpha drive (32:1) turning a 20 turbo 3 blade at 4200 rpm speed was about 50.
