and 
engine 
alignment 
must 
be 
checked 
and 
corrected, 
if 
necessary, 
before 
the 
boat 
is 
delivered. 
Final 
align-
ment 
should 
not 
be 
attempted 
until 
the 
boat 
is 
allowed 
to 
"settle" 
in 
the 
water. 
The 
oil 
level 
must 
be 
checked 
and 
oil 
added 
if 
required. 
While 
the 
boat 
is 
being 
run, 
the 
water 
connections 
should 
be 
checked 
for 
leaks.
