If you have ballasts, try playing with the front ballast. Add some weight and see what that does.
Thinking it may put more boat in the water, but up on plane may lift the back some.
We also put the plate all the way down, and I notice a difference in the number of people on the boat.
V-drives aren't the slalom course boat, so not sure other than losing some weight in the boat that there is much that can be done. Obviously, the faster you go, the less wake there would be, but I do 31-32 and I think that is about as good as it is going to get.
