Wondering why my boat drain plug is at the bottom not on the transom?

[kylejj]

water is barely able to get out because it’s about 6 inches from the back of the boat. Wish i had a transom plug

Put a clamshell scupper on the bottom, it will suck the water out while underway..

That is a style of drain that was on older (60's) boats. They usually had a clam shell facing stern. If you look at them while on plane, the clamshell holds back the water and the drain is clear. They work as well as transom mounted drain plugs, maybe better. If you can get to it easily, I would stick with it. The transom mounted drain plugs can be a real PIA to get to in most boats.

When underway, the clamshell creates a vacuum and pulls the water out thru the bottom. Very popular back in the 40-60's...Amazon has them, can be riveted or bolt and nut screwed to the bottom over the drain hole...Just be sure the plug is back in the hole before you stop....

If it sticks open it will sink you. Stick with what you have IMO

there is nothing to "stick open".
There are no moving parts.

Quite common for drain plug to be on the bottom on aluminum boats.

Ok, I see what you mean. I was thinking of a regular scupper with a flap or ball sealing mechanism.

Yep....gotta watch those !! When I had these clamshell drains, I either used a screw in plug or a rubber adjustable stopper type plug. A spare was tethered close by in case the original moved out of reach.
