As I posted previously I promised to post my solution.

First you need to get some trout balls.
Catch a trout and ...
8mm Floating trout balls or beads as they are also called.
#1) Using a #6 hex shank countersink I drilled through the cap from underneath. This creates a drain hole in the cap and a taper for the bead to fit into.
#2) The 8 mm trout beads have a hole for fishing line I filled by pressing in tip of a wooden toothpick soaked with glue and snap off and press in so none protrudes.
#3) Place two (2) trout beads into cap (2nd one adds to the bouyancy and pushes the first one into the taper). The beads are not hollow but do float.
#4) I cut a piece of flat plastic from another scupper and glued to the bottom to keep the beads in. Use care not to get any glue inside the cap. File the crossbar smaller than the threads so it does not interfere with the screwing in of the scupper.
You have a home made self draining scupper. The venturi effect speeds the drainage. Works on the principle of an old ball check snorkel.
Secondly to keep the puddle from occuring in the first place I am taking a 12" x 12" x 1/8" neoprene rubber sheet and cutting a deflector and placing over the handle recess to stop the geyser effect by deflecting broadside waves that channel into the recess.
I have two of the scuppers in my revolution and they work very well.
I did a lot of trial and error cutting tapers with dremel grinding stones and using o rings inside the cap. This worked best. The taper cannot be too big or the bead will not check the flow.
