@John: oh yes but those aren't flappers, they are the complete assembly with metal and stuff. You need to replace those when the metal has had enough of hot salt water
, sulfur etc. That's why we go for plastic fantastic instead, plus it becomes part of the hull.
Great job you did with the pipe! So you like plastic instead of metal too for the exhaust ;-) I'm afraid that if I would make something like that, I wouldn't have much left when ready... needing to re-cut pieces that end up too short etc. ;-)
@Gord: exactly those are the ones. But that "300" stands for 3.00" and the way to fit it around 2.50" is to cut it at the neck, after which you can overlap it where it is cut and put the hose clamp around. Not a pretty sight.
I am waiting for my hose clamp to fall off there, after which I will put a new flapper on and fasten it with monel wire and my handy clamptite tool. But the hoseclamp is not in contact with the exhaust water
so it's holding out pretty good... I put it on in late 2003.
Edit: that's funny
... I needed to edit to correct spelling (as usual) and instead of a "save" button I got "vote now". But it worked like the save button... and now I get the normal save button again ;-)
