Inserted the washer with the cut in the 12 o'clock position (on top) and only about 1/2 of the diameter of the washer went in. Make sure you find a washer that is just slightly smaller in thickness than the gap so that it does not slide all the way in. I just got lucky and happened to have one that was the correct thickness. This way, it takes up the gap yet is easy to remove at the end of the day. The gap on the other side was smaller and I did not have a cut washer for it so I left it as is but even with just one washer in place, 95% of the slop was eliminated.

Do NOT drop a flat washer in there as you may have a really hard time getting the platform off!

Below are pics to go with the description above. I have been using this method the last three or four times out and it has been working well for me. It eliminates 95% of the movement and is really easy to remove with a pair of needle nose pliers afterwards which is important for me as I have to remove the swim platform after each time out.
