Sorry I didn't reply sooner. I entered the wrong username (unknowingly) 5 times and it locked me out. It seems the spark forums needs security better than all my online banking and credit card accounts. I digress.
Here are the pictures.
The instructions came with a template for where to drill, but you can use the pictures as a guide too in case you lost it or it didn't come with one. The main thing here is that the left side of the mount is parallel with the upright corner of the ski.
You can use the stainless plate it came with to guide your pilot holes if you need.
The grommets work just like the iron cement anchors. You place them in the hole, and as you tighten, it pulls them in and spreads them against the side walls, making them fatter. I hope that's clear enough description.
You can see in the straight down pic there is the slightest of gaps where that grommet comes out of the plastic.
I wouldn't worry about sealant. If any water gets in there, I really can't see it becoming a problem.
On the right, where you mount it in the bag, I really can't see it being a problem where you drill. Higher like I have pictures seems to be the best spot for it being out of the way. After every 1/2 hour of aggressive riding, take a look down and make sure the straps are still tight, it does tend to come loose when wet.
Hope this helps
For what I use it for, well, here in central Florida, last weekend we had floatilla boat tie-up, and for the times we were listening to the band, I popped up the top and could chill in the shade when we weren't in the water or tearing it up on the water. Other than that, I expect to use it over the 4th when I use it to go to a bar where they host day concerts on their tiki area and you can drive up via the gulf.
