had boat ready to go in the water last thing was to fix some leaky thru hulls in the strbd side back that were dripping water into the boat and leaving nasty brown stains. so pulled out the thru hulls and water came out. nasty ,smelyy old water. not sure how to proceed? any help would be appreciated!

any pics? Water was coming out of the holes after you pulled the fittings out? Where on the boat are they located?
