[Public-list] Prop zinc installation tips

[Randy Katz]

Greetings, All, 

    Been following the prop zinc notes a bit.

    A very useful recommendation I incorporated came from someone on this
list, I believe.  I install the zinc with the boat in the water, diving with
a mask and snorkel.  (Yes, around here that requires farmer john wet suit
and a stiff drink o something when finished-- it's cold water!)
    With tools lined up on the finger pier's edge, I dive a couple of times
with a screw driver to remove the old zinc.
    I prep the screw for the new zinc with a bit of regular caulking (boat
life, etc.).  A subsequent dive sees the zinc tapped firmly into place with
a small sledge hammer (short handle, wrist strap) and the screw started.  A
couple more dives finish off the tightening of the screw with perhaps a few
more taps on the zinc for good measure.
    AS someone reminded us, there are casting edges or flanges on inside of
the zinc that prevent a tight fit on the shaft without that bit of banging
and tapping.  The caulking helps hold the screw snug without being difficult
to back out next time.

    Fun!
