I recently purchased a 98 22zx with a 7.4l TBI bravo 1 with 24 pitch bravo 1. I am turning about 4500 according to my gauge. What is the max rpm's for this motor. What pitch is others pushing with.

Sounds like you need to loose some pitch, I feel 24" is a bit steep for your setup. You are looking to get up close to 5K RPM wise. Look through this link for some ideas on what prop you should be using: http://www.donzi.net/forums/showthread.php?t=33017

Match you combo to some of the boats in the post!

Whay mop said!! TBI????????? throttle body injection??? or did you mean efi?

on that boat the most popular prop would be a 22 pitch with your engine..and if im not mistaken the revolution4 prop on that boat picked 1-2 mph..
