I'm just learning my way around the '07 LSV. While winterizing, I vacuum up every bit of water in the bilge. I noticed that my bilge pump isn't mounted to the hull in any way. On my previous boat there was a screw that went into a metal plate that there for some other purpose (skeg maybe?). It seems weird that the pump would just sit there not attached to anything. Is this normal or should it be attached somehow?

I'm stealing a photo from cab13367 as it looks the same:
