I have a 2012 188 Sundeck Sport and I'd like to get a spare drain plug. The most common size online appears to be 1/2". I measured the threads and they are 3/4", but the square nut is 1/2". I assume I'm looking for a 3/4" drain plug? I would have thought whatever the Hurricane takes would be really common since there's so many of them out there. I found this, is it correct?
