I have a 2000 Wellcraft Excalibur with a 565 cui engine put a bravo XR on it with a 26 pitch Bravo prop and can't seem to get enough bow lift any thoughts?

check the hull for a hook use a straight edge to find if you have one.

What do you mean by hook?

If you place a 4' or longer straight edge on the bottom of the boat. If it is tight at both ends and you see some daylight in the middle you have a hook. If there is daylight at either end, you have rocker.
I had less than an 1/8"hook in the last 4" of my hull. I removed it with a belt sander then repainted the area. It made a huge difference in how much of my hull was in the water when running .

What size boat????

Griff,
Its a 26.5 I added 280 K trim tabs as well.

How deep is the propshaft below the bottom???

If the drive is at stock depth it should be deep enough, but maybe not. Lowering it 1" with a drive spacer will give more leverage to lift the bow. Prop work will also help. Add cupping in the right place and rake angle.
