I will be hauling next week and would like to change a few thru hulls in the process.
Is there a fairly standard size of thru-hulls ?
For example can I assume that the head
will be 3/4 in and 1 1/2 out?
how about the galley
sink? From what I can remember it looks like it might also be 1 1/2
I am away from the boat right now so I can't take measurements. I would like to order some parts
online (which are much cheaper) so that I have some on hand when I get to the boat.
Also, if the thru-hull/seacock is in an enclosed cabinet where nothing could really hit it. Is it still recomended to use the flange type with the 3 thru-bolts?
I will be making fiberglass backing plates
as described in the thru-hull primer
Thanks for your help
