    27p bravo 1 FS. What's your number?

    Setup: 250 pro xs, 1.75 sportsmaster
    Prop: 27p bravo fs, robbie tuned
    Load: 3/4 tank of gas, full livewell, 3 fishermen, dual 10' pp, 3 lithium batteries, 40#s of tackle


    Hit limiter @ 77mph. I may want a bigger fishing prop.

    Anyone run a different number on this prop?

    Your gonna need a 30 IMO to get the 1.75's off the limiter.

    Im running a 28 bravo xs with similar setup ..i sent the prop out and had some cup added to it to carry the bow better at speed..it runs 80 ,81 now fully loaded..im right at 6000 rpms..i fish smaller lakes with tight turns and sea walls..if your looking for top end my pro max or hydromitive are faster props .for me the bravo handles better..

    Thanks for the offer river rocket but I have family in town for the holiday.

    I have a 28p hydromotive that runs faster but holeshot not as great as the 27p. Going to try maybe a tuned 29fs.

    bass dangler...you are going to need a 30P bravo and a 30P XOB with that setup. I had the same gears and motor on a 2+2 and a Pro 2 seater and the 30 is the way to go. The 30Pbravo was a Robbie built prop and the XOB was from Todd at hydromotive. My hydromotive 28P is now my favorite on my Pro 2 seater with a 300 and 1.62 gears.

    All I know is that with my 2+2 and my pro (2 seater) and a 250XS\1.75 gears is that a 30P prop was dead on with the RPM's running WOT and holeshot. The 28 Promax will be more like a 29 Bravo as they run a bit stiff. I had a 30 Promax and loved it. drove great, hole shot great.

    Different boat and different setup but my 2+2 w/250 1.75 sporty combo running a ton of gear finds the limiter with a 28 Bravo XS (stock) at 85ish solo and 81 with 4 adults. My 30 Promax solo runs 91.1 on the limiter solo and a tick over 90 with 2 plus a full fishing load. Never have tried it with 3/4 passengers yet. A 32 is required for me to stay off the limiter and that's still with a load. I have not tested empty yet but feel like I will find the limiter when I do!

    My 2+2 was too sluggish with a 30 ProMax running 250/1.75 sport master. Two full size people and gear was no fun. I went with a 29 ProMax and was a lot happier as I could still break 90 mph.

    I am running a 300 and using the wedges. Bass Dangler where in Wisconsin are you? I have a place in Prairie and I have a couple props you could try. If you ever get over that way. The guys telling you a 30 XOB are being pretty optimistic with your set up in my opinion. I have basically the same set up as you.

    Hoboken it depends on what you like. If you want be quick and 85 a 27/28p is best if you want less holeshot and
    90 hello 30P
