    New member!! And need help choosing a prop

    Hey guys I have a Baja 275 w/496ho I currently have a 21p revolution 4 prop that was on the boat when I bought it. The pitch is to low I'm spiking 5500 rpms. I went on mercurys prop selector and they recommended 3 props a bravo 1 22p, a rev 4 23p, and a mirage 23p. What prop do u think will give me the most speed/ best performance I hear the 4 blades have better hole shot and handling but that the mirage is usually about 2 mph faster top speed. My boat currently runs 61 on gps at 5400rpms would love to see 65 maybe 66 if possible and get the rpms down to 5000 where they should be. Any input is greatly appreciated

    I would try the revolution 23.It has a bit less diameter than the Bravo,your x dimension is most likely in a good location for running a four blade over the three blade.That should bring you rpms's down to about 5 grand and get you a few mph.

    I would definitely stick with a 4 blade in a single..much better handling...my guess on your setup would be a weak 26 Bravo 1 or a 25 Hydromotive QIV...If you have the ability to try some, i would sure look into these...the Bravo props tend to be a bit weaker than the Hydro's..( pitch wise)..could be 24 Bravo and 23 or 24 Hydro too..just have to trial and error

    Try a 24p Bravo prop. I had that setup on my 1995 272 with a 502Mag and it worked great. You might have to have it labbed if your looking for a optimum setup, but should get you close to where you want to be. Baja's like bowlift and to get this you'll most likely need to send the prop out to have it worked. I'd recommend Bblades. Brett knows Baja's and usually gets them the first try.

    call Brett at bblades you could try both props rev 4 23 and a b1 22 or 24, I'd put my money on the rev thought. you have a deep propshaft about 7 -7 1/2''.

    Check your tach. Rev limiter is at 5150 on a 496HO. Unless that ECU was sent off the Whipple, you are not turning 5,400 - 5,500 RPM.

    Eh I'm pretty sure the tach is correct the alarm will sound around 5400 or at least when the tach says 5400...

    Labbing usually picks you up 200-250 rpm's. Blueprinting it for you boat is usually how you pick up more. You'll only know after you run it.
