Epoxy with filler in place.
Be sure to pack the epoxy around the tube.
Tape on tub bottom, around shaft tube.
To anneal the tube, simply heat it with any
propane torch, until it changes color.
You will see the brass color change to a sort of
blue. It only takes a couple of seconds, so watch
for it.
When you see the tubing change color, move the
flame slowly down the tube until the whole thing
is done.
Put a screwdriver in one end of the tubing to hold
it while you heat it.
Try not to anneal the last inch or so.
You can either set the hot tube on a heat proof
surface (concrete will do), or you can quench it
with water until cold.
When cool, use a ScotchBrite pad or coarse
sandpaper to scuff the brass tube.
Put the shaft tube through the hole in the tub
bottom, and through bulkhead 3.
Put the end that you didn’t anneal towards the
engine.
The tube should start ¼ inch behind the engine,
and continue about 6 inches behind the transom.
If the tube fits okay we can epoxy it in place. If
not, sand the opening(s) until it does.
Glue the shaft tube in place with epoxy and filler
(to thicken).
Be sure to sand the shaft tube where the epoxy
will be.
To prevent epoxy from running out the bottom of
the slot, use tape to make a “dam” on the bottom
of the tub.
Allow to cure fully before touching anything.
