SECTION III 

Propeller Installation & Removal Procedure 

 

INSTALLATION 

1.  Inspect  propeller  shaft  seal  for  leakage  (oil  in 

drive). 

2.  Inspect  propeller  bore  and  prop  shaft  for 

cleanliness. 

3. 

Install 3/8” square x 3” long stainless steel key, 
taking  care  that  key  is  firmly  seated  in  keyway 
and not climbing up end of keyway. 

4.  Coat  shaft  and key  with 50-50 mixture  of  white 

lead and lube oil, or Never-Seeze Compound. 

5.  Install  propeller  to  shaft,  being  sure  that  key 

and  keyway  are  properly  aligned.  Gently  push 
propeller all the way on taper until taper fits up. 
Slide  propeller  off  taper  to  check  taper  fit  and 
re-install  propeller  with  a  firm  push,  seating 
taper. 

6.  Block propeller with soft wood close to hub and 

install  jam  nut.  Tighten  to  150  foot  pounds 
torque. 

7.  Install  lock-nut,  holding  jam  nut  and  torque 

against jam nut to 300-400 foot pounds torque. 

8.  Install new 5/32 x 1 ½ stainless steel cotter pin, 

bending both legs around shaft. 

 

 

REMOVAL (Always use puller) 

1.  Remove cotter pin. 
2.  Remove lock nut. 
3.  Slack jam nut about 

½”. 

4.  Install puller using 3/8 

– 16 UNC hardened steel 

puller bolts. 

5.  Block  propeller  close  to  hub  (using  soft  wood) 

against  firm  footing  and  tighten  center  puller 
bolt.  If  propeller  does  not  break  loose  by  hand 
with  15”  long  handle  wrench,  apply  flame  heat 
to propeller hub, but do not heat so that metal  
discolours. If propeller  was properly installed, it 
should be off the taper. 

 

Corrosion Protection 

 

To  help  prevent  electrochemical  corrosion, 
each  U360  drive  is  furnished  with  sacrificial 
zinc  anodes  which  must  be  replaced  when 
they  are  substantially  “eaten  away”  to 
maintain their effectiveness. Of course, these 
anodes must not be painted over  since their 
effectiveness  depends  on  their  being  in 
contact with water. 

It is suggested that additional zinc anodes be 
attached  to  hulls  of  metal  vessels  to  reduce 
corrosion  of  the  U360  drive  and  the  hull 
itself.  Vessels  used  in  fresh  water  may  not 
require  additional  anodes;  but  vessels  used 
in  seawater  usually  require  liberal  quantities 
of anodes to ward off costly corrosion. 

 

 

 

Attachment  of  the  drive  to  the  hull  must  be 
accomplished with fasteners which are close 
to the drive and hull materials in the Galvanic 
Series.  Since  the  U360  drive  is  cast  ductile 
iron and most hulls are welded carbon steel, 
the use of steel or stainless steel fasteners is 
recommended. 

 

DO NOT use copper alloy fasteners.
