5. Mark the location of
one of the outer holes on
the propeller. Use a GPM
Dead Center Hole Locator
(GPMR8130) to center and
start the hole.
6. Remove the propeller
from the engine and drill
the outer hole on the
drill press using a #35
(.110"/2.81mm) drill bit as
a pilot hole. Next use a
1/4" (6.28mm) drill bit to
fi nish the hole. In order to
achieve a clean fi nish on
both sides of the propeller
drill only half way through
the propeller with the fi nishing drill bit. Then fl ip the propeller over
and drill completely through the hole.
7. Use one of the 655mm SHCS with 6mm lock washers and fl at
washers to align the propeller washer on the propeller and use the
Dead Center Hole Locator to mark the position of the remaining holes.
8. Drill the remaining fi ve holes in the propeller using the same
technique on step 6.
9. Mount the propeller to the engine using the 655mm SHCS with
6mm lock washers and fl at washers. Be sure to use threadlocker.
