1.  Place the powerhead/outer Tube As-
sembly on a clean, flat surface, spark 
plug facing up.
.  Use the 4mm hex wrench to loosen the 
tube clamp and index screw. Verify that 
the D-shaped shim washer is positioned 
as shown in Figure 4.
CAUTION! 
Do not remove the D-shaped shim
washer! The shim washer prevents
damage from overtightening the tube
clamp screw.
3.  Slide the outer tube into the tube clamp 
until the tube bottoms. If installation is 
difficult, rotate the outer tube or main 
shaft slightly until you feel the main-
shaft splines engage with the gearcase.
4.  Position the outer tube so that the index 
hole on the outer tube is aligned with 
the index screw on the gearcase tube 
clamp.

CAUTION!
Do not force the shaft tube into the

5.  Using finger pressure only, thread the 
index screw into the index hole located 
on the outer tube until it bottoms out.
6. Tighten the index screw and the clamp 
screw firmly.
NOTE:
It may be necessary to twist the outer tube 
slightly for the index screw to be inserted fully.
