Probably a stupid question, and I think I have it figured, but want to make sure and couldn’t find the info in the manual or online. I have a Lowe Stinger 178 and it has 3 drains/plugs/outlets and I’m just trying to confirm what each one is. The center is obviously the main drain plug and it’s a captured system. The left appears to be the live well inlet, and I am assuming the right hole is the live well overflow? Is that correct? If so, should I plug the live well overflow if I’m not planning to use the live well? 

My Ranger RT178 looks nearly exactly like that.  The one on the far right is the standard drain for the livewell.  You don't need to do anything with that.  Look inside the livewell, there should be a plug.  To prevent drainage, simply put the plug in inside the livewell.  I attached a photo of mine.

 

The one on the left is the livewell inlet and the middle one is the main boat drain plug.

 

The overflow for my livewell is about halfway up the transom (second photo).  It needs to be above the water line on the hull of the boat, otherwise the water would not drain out of the top of the livewell.

 

 

 

If she ain’t sinking don’t change anything

Ill have to look at mine, but I don’t recall having another drain further up the transom aside from the splash pan drains. I do have 2 ports on the starboard side, I know one is bilge pump outlet, maybe the other is the live well overflow?

Thats possible.  My bilge outlet is on the starboard side just above the water line.

I would plug it to be safe, I had to learn the hard way. Mine stays plugged unless I need to use the livewell, but I don't really use them.

I dont use livewells, so I put a plug in each open drain or intake. It just makes me feel safer. The plugs are removable if I ever wanted to use the livewell or sell the boat.
