@GregHind I would post pictures, but I'm currently in Florida and the boat is in storage for the winter in Nebraska. Tall probably isn't the right word to describe the wakes, it's not the height that's the problem as they are similar in size to an inboard wake, maybe slightly higher. The thing I'd like to find a way around is the hardness of the wake. Does the plate help with that? Also where does the hardness come from? The only thing I could think of is the prop mixing air into the water, but that still doesn't seem likely.
