Just repowered my 21 XDC with a 2021 250 pro xs, torque master LU with five water inlets on side, 14” setback, 27TXP, 1 inch below pad. I’m hardly getting any bow lift and also losing water pressure once I get it trimmed up probably need to plug the top holes on LU I’m not running it hard until I fix the pressure at WOT. Im
curious to what everyone’s setup and numbers are also any advice would be appreciated 🇺🇸
You might be too high on the jackplate for the load you have.

Not sure this will help. I have a 21XD with 250XS and a torque master lower that has 1:62 gears. I am running a 26 Pro Max prop. My rig is set up 3/4" below the pad. When I was studying what to do with my boat the consensus was 3/4 was a good safe number all around. Did you purchase the prop new?

I’ve had the prop for awhile, I experimented with motor height yesterday and with the 4 Strokes without plugging holes on the LU u have to be 1.25” under pad to keep water pressure at WOT. Gonna plug some holes today and raise
it back to 3/4 under pad and see how that goes
