I recently bought a new crappie style jon boat.  Its a waco c-14 and makes a great little poor mans bass boat.  The only complaint I have with the boat and its a very small one is that I can get the drain plug to complete seal.  I have got it as tight as it will go and still be able to get it in the hole.  Its not a major leak by know means.  I will have about a 1/2 a coffee cup full of water in the boat after about 6 or 7 hours on the lake.  Any tips on stopping this little leak.  Thanks for the help....

First, if it's the expandable type you screw, you put it in the hole and then screw it down until it's tight.  If it's the type the screws down and then folds over to lock, snugg it in the hole and the lay it over If you are doing that and it's leaking, check the brass sleeve insert and make sure it's not cracked.  Next make sure it's not leaking around the sleeve flange where it's crimped into the hull.  If all that's ok, try another plug.
