stupid thru-hull measurement question
I'm shopping for a replacement thru-hull and seacock, but I'm confused about how they are labeled. The hole is about 1/2 inch diameter, its 3/4 inch if I measure the width including the threads. Do I buy a 1/2 inch or 3/4 thru-hull?
(I remember reading somewhere that you measure the hole, but the site says "thread size", so I'd think you measure the whole thing, hence my confusion)
