    Yes. And then you enter the might as well zone. Since it's new to you,you will need to replace the prop shaft packing as well as the rudder packing. Not hard to do anyone here can walk you through it and I'm sure there are youtube videos as well as engine alignment ones.

    Rudder can be a little tricky. I've seen a couple different configurations for how it's contained. But if you're on the hard you don't need to worry too much about dropping the rudder. Best to be supported or at least soft place to drop.

    You likely can replace the coupling and the shaft stuffing without removing the rudder. I had enough room by positioning the rudder for max shaft/prop travel.

    Really, you should be able to do both packings without dropping the rudder. Just easier. Just need to be able to remove the gland nut, dig out the old material, cut new packing rings and install/adjust.

    Only done my own (2 Shammy's) and been a decade for me, so I'm rusty.

    Stainless is available too. Just saying brass has been around a long time. And it the reason anodes are so important.

    Define "long time".

    The Bronze Age spanned from 3,300 to 1,200 BCE

    ;)

    JUST my opinion, but brass has very few uses on a salt boat.

    The big difference between brass and bronze is tin in bronze and zinc in brass. By the way. I would use bronze first too. Brass has been used at least since the 40's and is less brittle. It is cheaper and has been readily available. Bronze not as common . Alot of the old boats had brass props, shafts and valves. I used to part out old boats to supply parts for home builds. Bronze was only common in the pricey boats. Talking the 50s and 60s. I wouldn't use wood now either.
