I think you're probably kidding, but regardless I need to address that further because I just thought of something I meant to say earlier.
If your prop is one that is meant for medium to high-end running (higher pitch) then if you put too much weight in the boat the prop could spin too fast at the slow speed causing a washed out surf wake. As you add more weight to your setup it is usually advantageous to reduce pitch of the prop so that your motor can push the weight efficiently and your wake isn't washed out.
I'm really only familiar with prop sizes for the older boats, so I don't know the specs of what the stock prop on your 20V would be or what to recommend, for that matter. That make sense to anybody else, or am I blowing smoke?
