Separate bilge drain plug?

[C]

Currently have my boat at the mechanic to repower. Went back and forth on motor options, but after a deal fell through on an older Johnson I ended up with a 2013 90hp etec. While looking around the low area where the drain plug is, I noticed a rubber stopper for what I assume is draining the area under the deck. How is this plug usually treated? I would think left out all the time?

In Minnesota plug has to be out while transporting to and from lake. So you don't transport Eurasian watermilfoil from lake to lake. Old timer taught me a trick to get every drop of water out of hull. Run a shoe string or piece of cloth from the lowest point in hull where water can't drain out drain hole and let it hang down half a foot below hull. Twist tye drain plug to tye down strap so you put plug in after removing strap .. Most people only forget to put plug in once ... you never forget again ... LOL

The string is a great idea. The plug I?m talking about is a separate one in the recessed area where the main plug is. I may have to take a picture when I get it back, I?ve searched the internet with no luck on what it is.

Yes .. run shoestring into that hole and out drain hole ...

This is what I was looking for! Thank you! So it looks like I just need to periodically remove.

After every uses , I would pull plugs and tilt boat up as far as possible. Then run shoestring through hole and let sit for a few days.

Thanks! This was exactly the information I was looking for, I'll be following this advice. My boat will be stored inside when not in use with the cover on, I have a couple buckets of "Damp Rid" to leave in it when not in use.

Boats were never meant to get wet ...

Haha! Hoping to share some pictures once I get the newer outboard on. Here it is after removal of the old tower of power.
