I just wanted to share what I have done to create a little more storage in my boat and how I kept most of the rain runoff from going into the cooler.

Extra storage:
This is just a plastic bin that measures 15 7/8" x 12 7/8" x 6".
I keep an extra TM prop, pin and nut for TM, WD-40, zipp ties, hub kit, and fuses in this bin.



Next is a pic of the weather stripping I used to keep most of the rain water from draining into cooler. This is just some rubberized weather stripping that I ran around the cooler opening in the shape of a U.
