The Hurth HBW100 transmission on our Universal 5432 diesel in our O'Day
37 CC is kaput. I have bought a replacement tranny but I am having a
hard time finding someone to remove the old one and install the new one.
Our marina's mechanic is out sick with a bad back and won't be back
anytime soon and the marina has no one else.

How big a job is this as a DIY project?

It depends. Do you have a good tool set with the
right size sockets and wrenches for the
transmission? If so, can you get to all of the
mounting bolts that connect the transmission bell
housing to the back of the diesel and the bolts
that connect the output shaft of the diesel to
your prop shaft? Is the shift cable and lever
readily accessible?

If the answer to those questions is "yes, yes, and
yes", then it should be a pretty simple job
_assuming_ that you have obtained the correct
transmission for replacement, and the bolts are
not siezed by corrosion.

So I'd say that if you can look at the
transmission and get a socket on all of the
mounting bolts give it a go. Just be careful not
to damage any of the bolts by rounding them off or
snapping them. If you feel at any time that you
are in over your head, STOP and get a competent
mechanic.

Good luck with it,

Many thanks. The unit is remarkably accessible unlike most things in a
sailboat engine room. My main concern is those corroded fasteners on the
flange between the prop shaft and tranny. They have been bathed in salt
water stuffing box drip -- sometimes more than a drip -- for years. Before I
break anything, is there a really. really good loosener upper for corroded
fasteners?

I have learned to sacrifice a nut when necessary. That is, if the
coupling is held together with bolts and nuts, rather than busting a
knuckle, or the bolt, just use a nut splitter to take off the nut. The
nut will be destroyed, but will come off easily. This is especially
handy when removing a nut corroded onto a stud - it saves the stud, and
eliminates the risk of breaking it off.
