I only ask as I am in a similar position and wondering if it's going from a b1 to a Q4

Bravo 1 and Q IV-X are similar and lift is pretty nuetral and they will help lift the bow. Q VI will lift the stern more and bow less.

Are you referring to X dimension, or prop height? People get these mixed up all the time. Are you questioning your engine height or your prop depth? X is the height of your engine in relation to your drive and prop height is is depth below the boat which is completely separate and adjustable other than cavitation plate.

Prop shaft CL to pad bottom/bottom of boat. Currently 6 3/8”

I’d see if you can track down Wild Card 09 or IGetWet on here. They’ve both spent a lot of hours setting up 25 outlaws. Probably the closest you’ll get.

Thanks for the advice. I did

I may be complicating things, but I’m starting to consider some other options. A question I have is with regards to adding an extension box. My assumption is that a neutral box doesn’t change your ex dimension and so the only change that is possible would be to add a Shorty ifit looks like that will run better. However, if you add an extension box. it looks like that will run better. However, if you add an extension box that raises the X dimension you could use the standard lower but net a higher prop. The question I have is this is it better to run a neutral box and a Shorty or run a box that raises the next dimension and run a standard?

A neutral extension box with 12" set back will put the prop about 1" deeper due to the transom angle. Transoms are usually at about an 11-12* angle.

Ext boxes work well on some boats and others they do little nothing for. You don't really see any 24, 25 or 26 Outlaws with ext boxes.

What are you hoping to gain?? How does the boat ride now??
