Factory prop
 
Hello all, I have the '97 z252 shabah....7.4/b3.....the pitch on the props is 28??? That seems a little high to me. Can any of you tell me if they are the factory pitch props?....too, how do I find out what my hp/torque is for the engine I have(factory) ....thanks guys/gals

What is your RPM at Wide Open Throttle? I have the 454 Mag in my Z252, with 26 pitch props, and it works great!

On the Mercruiser page, your 7.4 is listed as having 310 horsepower.
