Yes, your retroactive google definition of stagnant is correct. However, a more "still" area of water in a marina where a boat may be moored is NOT going to be stagnant. You're grasping at straws. Even if somone's definition of stagnant slightly differs from someone else's, you should be able to infer from the conversation what is meant (especially after we further explained it).
I'm always open to learning new things or being corrected if I'm mistaken. For example, Skunk pointed out SS underwater scoops and such. I had never seen these before so that was interesting to hear about. BUT, note the reference to "trailer boats".
It seems as though you haven't headed my recommendation to go back and re-read, or comprehend, as it seems you're completely glossing over what I've written and aren't taking the time to understand it: I have never used SS below the waterline because (1) It is not approved for that use, (2) Bronze IS a more durable metal, (3) I've only dealt with boats that are fully certiified and (4) I would not, personally, use an inferior product if someone is trusting me with their hard earned money. Again, AGAIN... Because I've never used it, I can't give a recommendation on how well it would fair for an in-water boat. What I DO know (facts) is that Bronze and Marelon are superior in this application. And, AGAIN, using SS below the waterline for a thru-hull fitting might be OK, depending on a number of variables. But it then becomes more important for the owner of the boat to do his due dilligence to keep an eye on it. For example, the gentleman, somehwere in a previous post, that said he is using it - I've seen enough of his posts to know that he'd be one to check on it (sorry - I forget who posted it, but I remember typing pretty much this same response about it before).
Seasick answered your raw water pump "attempt" at justification. We are not talking about sewater pumps - different application.
Mustang, in all seriousness and with no malintent.. just being straight with you... at what point do you suck it up and just admit that there's much more to this underwater thru-hull stuff than you knew about and maybe just zip your mouth and try and learn something? As I said before, it's totally OK to NOT know something - at one point NONE of us knew anything about this.
Oh, another reason I wouldn't use SS (I mentioned this briefly before) is that I don't want to chance an insurance company denying coverage for a sunk boat due to corrosion (although, also I said before, it's not like it's going to happen magically - it takes time - and with prudent monitoring it should be OK). While I don't know this for sure, I think it's a safe bet that an insurance company would try and classify this, at the least, under something like "lack of owner maintenance" and possibly "negligence". ESPECIALLY if somene paid me to do the work as then I'd be liable.
Remember, this discussion isn't about whether you can or can not do it. It's your rig - do as you wish. The point to my reluctance to let this go is education. As long as someone fully understands the risks, go for it. We're all big boys and big girls and can make our own decisions. But make those decisions as sound as possible, basing them on as much factual information as you can. One of those facts is that bronze IS better than SS.
