Hi i have an baja 252 boss with an 540 engine

540ci BBC Engine Spec Sheet
Estimated Peak Hosepower @5200rpm = 693 horsepower
Estimated Peak Torque @5251 rpm = 700 ft lbs

bravo 1 1:50 gear ratio

What propeller do you recomend for this boat with this setup? and what pitch and propeller diameter?

Hope you can help me

My best guesstimate would be a 28 bravo 1.

I have a 29 mirage plus , lots of bow lift $ 225.00 shipped standard shaft

thats a good start for the money and its a mirage plus, then try a 28 or 30 b1. if your not happy with the 29. your X works better with a plus, unless you have a shortie drive.

I have a 5 blade 25.5 x 15.5 - 22degree that will definitely carry the bow.

Does your motor have a supercharger?

do you think this props they sell on ebay is good? ore do you recomend an 3 blade prop?
