I find that a towel about 2 feet square is very helpful for pulling the speed wheel. I stage the plug near the wheel and then place the towel over top with the edges all tucked into the sump. I work on the cabin side or "top" of the towel, the wheel and plug being underneath. I grab the wheel in one hand (with the towel) and grab the plug in the other hand (with the towel). The draping edges of the towel stay in the bilge sump area and as I withdraw the wheel the towel catches the geyser keeping the water in the bilge. The plug is in my other hand ready to be inserted.
Sometimes letting some water accumulate in the sump helps to reduce the geyser effect as well. I keep a medium bristle tooth brush in the sump to scrub the wheel. The extra water is nice for rinsing. The wet towel is rung out there in the sump and then used to clean up any drips or spills.
