hey derekdean1, you should pump her up, top that bitch off with a barrel pump, not too hard on the floor(no bleader valve), only 5 full pumps. take a 5 gallon bucket filled with water, put a ton of dish soap in with the warm water, mix it up like you wanna make lots of bubbles and take rag or scrubby to the boat. scrub lightly over the entire thing(bottom of floor, top of floor) every square inch. those bubbles tell the truth about pin hole leaks, be sure to have a sharpy with you, mark all the leaks after wipin individually with rag. do some quick math. for every pin hole subtract 5 or 10 bones. I did this when I baught a shredder. it 100% tells the truth about the pin holes.
by the way I will be rowin a maravia down the grand starting in a week. I love those boats cuz they are tough, but just wish we could figure somethin out about the floors and storing them. good luck and dirka dirka
