Ok, I admit upfront I am being lazy. Yesterday, after I finished cutting some Hypervent material for under the V-Berth cushions, I dove into the hole under the bunks to the stemhead "inspecting" things. The chain locker thru-hull fitting was in great shape, but I noticed the drain hose was a bit funky, sticky and old—so I will replace it. Unfortunately, I didn't remove the hose at the time when I was crunched up in the bow. Dang! With the hopes of saving my old bones another roundtrip bow dive, just to measure, does anyone know the ID dimension of the drain hose? Next time I go up there I want a new hose in hand.
Hi Noah, it's been a while, but believe it was 3/4" on my boat when I changed the hose and thru hull.
