Screw length mounting bilge pump

[Halfhitch]

now you've gone all the way through and created a fountain inside your boat... which generally isn't a a good thing.......

.....ha ha ha ha....

Put a little 5200 on it and jamb it in! Not going to be a problem. It's better than having the pump or float switch flopping around down there.

They are all sinking anyway! Only difference is how fast.

It's a "better safe than sorry" thing. In theory, it could be fine. But screwing into a 1" thick hull with a 1/2" or 3/4" screw just isn't the wisest thing to do. Screwing in creates, essentially, a small spot where the hull is now only a 1/4" thick and more susceptible to opening up (it's different than a seacock).

You're not screwing into the hull. There is wood in the area just in front of the garboard drain. Right where Grady screwed the OEM bilge pump.

I was only responding to Hookup's comment which was specifically asking about screwing into the hull.
