Flange Alignment - Direct Coupled Models 
Install 
the 
propeller 
shaft 
flange 
on 
to 
the 
propeller 
shaft 
and 
tighten 
the 
two 
clamping 
bolts 
on 
the 
spli

hub 
(none 
on 
RV-lOD). 
A 
self-locking

Many 
good 
installations 
are 
ruined 
by 
improper 
shaft 
flange 
alignment. 
Accurate 
alignment 
will 
ensure 
a 
smooth 
operating 
drive 
train 
and 
eliminate 
many 
problems 
that 
arise 
due 
to 
misalignment. 
Final 
alignment 
should 
not 
be 
attempted 
until 
the 
boat 
has 
been 
allowed 
to 
"settle" 
in 
the 
water. 
After 
the 
engine 
has 
been 
installed, 
adjust 
the 
mounts 
per 
manufacturer's 
instructions 
until 
the 
pilot 
diameters 
of 
the 
gear 
shaft 
flange 
and 
the 
propeller 
shaft 
flange 
engage 
freely.

faces 
together. 
Without 
rotating 
either 
flange, 
check 
with 
a 
feeler 
gauge 
in 
at 
least 
four 
places 
as 
shown 
in 
the 
illustration. 
If 
the 
maximum 
feeler 
gauge 
that 
can 
slip 
between 
the 
flange 
faces 
at 
any 
point 
is 
.003", 
the 
unit 
is 
properly 
aligned. 
If 
a 
thicker 
gauge 
can 
be 
inserted 
at 
any 
point, 
the 
engine 
must 
be 
readjusted 
until 
proper 
alignment 
is 
obtained. 
Turn 
the 
propeller 
shaft 
flange 
1/4 
of 
a 
turn 
without 
moving 
the 
gear 
shaft 
change. 
Try 
inserting 
the 
.003" 
feeler 
gauge 
as 
descr 
ibed 
above. 
The 
gap 
will 
not 
change 
if 
the 
propeller 
shaft 
is 
straight. 
If 
it 
increases, 
the 
shaft 
or 
flange 
is 
bent 
and 
must 
be 
removed 
and 
straightened. 
Rotate 
the 
propeller 
shaft 
flange 
in 
two 
more 
1/4 
turn 
increments 
and 
repeat 
the 
procedure. 
The 
pilot 
diameters 
must 
be 
rechecked 
to 
ensure 
that 
they 
still 
engage 
freely. 
Secure 
the 
two 
flanges 
together 
with 
the 
heat 
treated 
bolts 
and 
spe-
cial 
high 
collared 
lockwashers 
supplied. 
Engine Alignment - Independent Models 
The 
engine 
must 
be 
adjusted 
so 
that 
the 
alignment 
of 
the 
flexible 
joint 
is 
within 
3'. 
An 
accurate 
steel 
rule 
should 
be 
used 
for 
this 
purpose 
as 
shown 
in 
the 
illustration. 
On 
short 
installations 
using 
a 
flexible 
joint 
assembly, 
the 
faces 
of 
the 
flexible 
joint 
must 
be 
parallel 
within 
1/8". 
Measure 
this 
in 
at 
least 
four 
places 
around 
the 
diameter 
without 
rotating 
the 
assembly. 
With 
long 
installations 
using 
the 
#36 
tubular 
drive 
shaft 
(also 
on 
all 
RV-lOD'S) 
the 
distance 
from 
the 
#33A 
spool 
adapter 
to 
the 
bores 
in 
the 
universal 
joint 
which 
is 
welded 
to 
the 
tubular 
shaft 
must 
be 
measured 
on 
both 
sides 
of 
the 
joint. 
Rotate 
the 
shaft 
exactly 
1/4 
of 
a 
turn 
and 
measure 
to 
the 
same 
joint. 
The 
four 
distances 
must 
be 
equal 
within 
1/8".
