Dragging bottom with an inboard

First a little background. I am a 51 year old that has been around water and boating all my life. Most of it was waterskiing at our local lake. This lake is shallow (1' - 18') and small (1000 ish acres). Not a lot of traffic makes it perfect for me since I live there and can use it when no one else is out there. My boys and myself only recently started wakeboarding. We have a Glastron I/O that works ok, but we are thinking about upgrading to a true inboard boat. All my life I have been told by " the people that know" that an inboard wont last long on this lake. I know this lake like the back of my hand, and every year, at some point, I manage to drag bottom. It is mostly silt on the bottom and doesnt hurt my propeller now. My question is this. What happens to the gear that hangs off an inboard when/if it drags bottom? I understand that this is a vague question, and it it hits something solid, it will rip it out. How much force does it take to do serious damage?
