Whats up guys. I'm new here and the site looks great. I've got a simple question. I've got an 06 Glastron with the Mercruiser 5.0 and I'm trying to get ready for summer. There are 5 plastic wing nuts on the motor to drain the water for winter. I put them back in yesturday and went out to the lake. Well apparently I put one in the wrong spot because I had water coming out a different hole I didn't see. There are two on each side and one on the front. The one I left out was on the right side. But I had all five screwed in a spot. I know the one I left open needs one, but I don't know which one to take out? Is there any ports like the others that are left open?
