Thanks for everyone's comments. I took the hose clamps off the original
piping yesterday and it looks like it's a 1 inch external diameter,
threaded bronze fitting. Perfect. I'll find a bronze (or stainless?)
ball valve to match, drop it in with some teflon tape, and install some
good new hose. Looks like all I can get in terms of hose clamps locally
is 304 but I'll keep an eye on them. Freshwater situation so we'll see
how it goes.

If you use 304 SS hose clamps, try to see if you can at
least get ones with SS screws as well. In my experience, the
most common failure is when the clamping screws rust out.

Doubled 304 SS clamps should be OK, although you should be
willing to renew them once in a while. Not a big expense item.


Here's a shot with the current clear plastic drain hose with the clamps
removed. You can see the threaded connection partially exposed.

Ouch... hose clamped to threaded fitting? No no no. Of
course, it won't be like that when you're done!



I agree that the drains are a bit small but it looks like it's 1 inch
all the way, so to enlarge them at the point would be a more
substantial project, presumably also would involve replacing the
through hulls with larger diameter. Maybe that's a job for next season.


Could also try the aft drain idea, simpler than bigger
thru-hulls and could be made substantially larger.

Still not as good as an open transom though!
