Prop not in RPM rage

[tewfiddy1]

I have 23'Caravelle Interceptor with the 350 mag and Bravo1 drive. At Wide open throttle Im only at 4400 RPM's with a 13 3/4 X21 Vengeance stainless prop. The prop the Merc put on it to get the most power and speed. My Suggested RPM range from Merc is 4600 to 5200. Im getting 62 MPH at 4400 RPM's. Does anyone know what size prop I should get to be in the desired RPM range. Im putting Smart Tabs on for the hole shot, it could be a little better.
Thanks

I dont know much about props but you might want to try a 19 pitch this might raise you rpm by about 250 rpm as well as improve holeshot.I have a 21 ft elim w/a 350 mag and i turn a 21 to 4800 rpm at 59-60 mph(gps)64 speedo

a 19p will put you into the 4800-4900 range. 200 to 250rpm change per pitch deg. good place to start. are you trimming it up enough? i had an old shitty sea ray like a 75 with a 233hp ford motor that spun a 19 with ease and that boat was heavy as shit

I trim it up until it starts slowing me down. If I trim up to much I start losing speed. I have a friend who might have a 19 pitch prop, but I think it is for an Alpha drive. Do you know if I can use the prop on my Bravo1 drive?, thats one thing I have never tried to do. Also will the Trim tabs from Smart Tabs help with the RPM range difference?
Thanks all for the help

Thanks all for the help I think you can use the alpha prop on the bravo.I have used a prop from a bravo on my alpha drive to test out.
