So in answer to your question not a lot realy
It may be different depending where and how big the hole is I guess
This assumes your electrics are on a shelf in a console above the flooded waterline! Many smaller ribs don't.
If not, your battery will be a mess.
We've been awash twice. Put in gear and it rocks the water back, very little forward motion until you get a load over the transom and the nose up, then speed exponentially increases.
...assuming you've not holed a tube too!
