Prop for a Liberator

[S P E E D]

Hey guys, looking to get a prop for my 1990 251 Liberator with a 454 OMC King Cobra. Trying to figure out what prop to put on it. Its a left hand Prop and there's a Stainless 19 on there now. Not sure of the make cause there's now markings on it. Previous owner just nicked the edges of the prop on there and I was gonna upgrade to something to pick up a few more MPH.

I got her out this weekend and I had it at 48-51 MPH on the GPS and the Rpm was roughly 4800-5100 depending on Trim. Couldn't get a solid number cause the water was a lil rough but that's roughly what I was seeing. Boat was also loaded with full 100 Gallons of fuel and 4 people and loaded fridge of golden brown goodness! lol

If you read the stickies at the top of the page and the helps on the prop store page it will hewlp you understand prop selection While a 454 must have gobs of power a 25 footer that will do over 50 in rough conditions and a good load seems pretty close to right.If you give us the details of the motor and its rated rpm,gear ratio,
Details of the liberator; weight,length and hull form,Deep V?Load and activities.
Describe present performance.

No worries I just called BBlades.com and talked to Brett. Really good guy and I'm ordering up a REV4 19P to try out first through they're test program. I'm gonna also try out the 21 Pitch REV4 aswell. I'll post up the results once I get everything on and running.
