[Public-List] loose casting on propeller shaft at end of keel

[Peter Milley]

Hi George,
I believe I broke the seal of the cast part or cutlass housing. If you have
some concerns please share them. Here is an account of what I did;
Most of the calking that formed the gasket between the surface of the hull
to casting had worn away leaving a space on the lower side of about 24
thousands of an inch. After removing the bolts I rotated the casting a
quarter turn clockwise, cleaned the hull surface of old calking that
remained, re-calked the surface then re-turned the casting to its original
position. Once back in position I ran additional 1/16 beads of 4200 around
the casting, and with my finger worked them into the gasket area as if I was
packing a bearing. I then cleaned off the surface of the hull of any excess
4200 and allowed this to set up. Once this set up I could no longer rotate
the casting a quarter of a turn as it had solidly gripped the hull. I next
epoxyed the two holes. After the resin had set up I drilled pilot holes and
re-tapped new threads. The bolts gripped nicely in the new threads.
Peter

Peter, did you break the seal of the cutless housing (the cast part) or 
the stern tube (a bronze pipe)?
