an angle to the shaft line equal to
tbe angle
of tbe
sbaft log
to be
used (14
0
in
Fig. 12).
The
angle
this line makes
with tbe keel tben
determines tbe angle of wedge needed
(3
0
in Fig. 12).
The location of the
shaft bole can
now
be
determined.
Its
distance
from tbe transom will be controlled
by the dimensions of the rudder be-
ing used,
clearance
between
tbe
rudder and propeller, prope ller dia-
meter and
propeller
clearance
to
the bottom of the boat.
Locate the
after
end of
the
propeller
hub
wbicb will be at that
point- on the
prop sbaft
where the
rigbt
angle
distance from tbe prop sbaft center
to tbe bottom
of the keel is equal
to balf tbe prop
diameter plus two
inches. Mark a spot four incbes plus
balf
tbe widtb
of the
rudder to-
ward tbe stern along the sbaft line
from tbe after end
of tbe prop hub
line. Draw a line from tbis point at
rigbt angles to tbe keel. This line
now
represents the
inside of
tbe
transom. Meas"uing from tbis
point
to tbe
spot where
tbe shaft
line
passes tbrough
tbe keel
will give
tbe location of tbe shaft hole.
A wedge
can now be
cut to fit be-
tween tbe
shaft
log
and keel
as
previously described. Fig. 13 gives
