Tad, You are a pioneer! I don't trust those ratings. You may remember Gary and Bill and their VHF tests. Them I trust! I had a nasty cut on my foot a few years back, and got some "waterproof bandages" at the pharmacy. They held up through some wild sailing out on the wire for about 4 hrs. The cut opened up after some running on the beach to rescue a friend, but I think the bandages were still intact. If the pump is small enough, perhaps you could contact the bandage manufacturer, and get some that would cover it.Keep us posted. I'm sure your experience will provide a lot of valuable info for others in your predicament. PS: Let me know when you want to claim that beer I owe you. Maybe we can get Chris to join us. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
