Although I had to cut the length of the drive
bolt down about an inch because of the tight
quarters this little monster was able to wrench
the prop coupling off of my 1-1/4" shaft.
Mind you, this had been on since new in 1973,
and because the shaft is bronze and the
coupling is steel, there was some trouble with
corrosion fusing the two. Mapp gas was not
hot enough to get the job done, but the
oxy/acetylene 'blue wrench' finally let
this little beast get the job done.
