I know the topic of PVC elbows has been thoroughly discussed, and I even asked some questions about this waste discharge through hull in an earlier thread, but it's taken a new twist when I dug into it this weekend. My plan was to simply replace the elbows with a TruDesign equivalent, and move on. The 3/4" elbow came off easy. The 1 1/4" has an issue I didn't notice until I was nearly finished working the valve off.
Picture is before I started working on it:
After removing the valve, the 1 1/4" elbow wouldn't budge. Even then, as you can see, it would only make it a half rotation before bumping into a TAFG section. So, they must have threaded the elbow on while twisting from below and given it the last half twist after everything was nearly tight. In my frustration, I cut it all out, which I think was the right choice. The outside looked a little dicey, anyway. So I have to replace it with something (or just patch the hole as previously discussed). The valve seems to be just fine, so I can re-use it. Due to clearance, I think I need to stick with the elbow being first, even though I don't prefer that.
Here are the two options I've thought of:
1) Replace with a like setup - through-hull --> elbow --> valve
-- Certainly the easiest and cheapest solution to retain functionality
-- I still have to thread it from the bottom and it will suck for the next guy who needs to do something with this
2) Move/install a new speed sensor where the 1 1/4" thru hull was and put this thru hull/valve where the speed sensor was
--This seems like the better long-term choice - I think the holes are the same size and it makes it easier to install as I can thread everything together in pieces.
-- The thru-hull for the speed sensor doesn't require the side-to-side clearance that the elbow does, so it should fit even with a snug space down there (I may have to trim the white board above it back a little bit to pull the sensor in and out)
-- Definitely costs more - might have to buy a need speed sensor if the housing won't come out
-- Anything I'm not thinking of?
From what I've seen from @Roger Janeway on Nora J, his throughs are in completely different locations; nothing that close to the TAFG.
Appreciate thoughts and/or other ideas.
