I have seen this as well as zincs on the inside of the shaft. Attended a loss
where the sea water pressure pushed the carbon/graphite flange against the
stainless rotor as it is designed to do. Unfortunately the set screws were not
hardened steel, corroded, slid up the shaft and the vessel, a 46 Hunter which
had just been delivered and not used by the owner yet , sunk at the dock.
CTL, brand new boat. A small hose clamp could have likely slowed this down
enough to allow time for someone to notice what was going on. I have since
that time always recommended a stop clamp snugged about 1/16" forward of the
rotor. BTW, that hunter was taken back to the factory, rebuilt, sold again. I
delivered it to Norfolk, got off the boat. On it's way to ST. Thomas, the
rudder fell out and they lost the boat.... John McDonough AMS Rye, NH
I see hose clamps on the shaft about 1/4" away from the gland, both on
dripless and regular glands. The alleged purpose is to prevent the
shaft from slipping out of the coupling if the coupling set screw comes
loose - WIRE THE COUPLING SCREW!
