Propeller Drilling
Use a drill guide to drill four holes in the propeller. The guide ensures that the propeller bolts align
with the driver and do not cross-thread. Using a drill press is highly recommended.
1. If your propeller has a 10mm (0.39 in) center
hole, move to Step 2. If not, use a propeller
reamer to enlarge the center hole to 10mm.
2. Place the drill guide into the propeller center
hole.
3. Align the bolt pattern where it is convenient
when mounted on the engine. See below for
suggested alignment. It is best to check this on
your engine fi rst.
Attaching the Propeller and Spinner
Refer to the Propeller Drilling section for
instructions on how to properly drill a propeller.
1. Remove the 4 propeller screws from the prop
driver.
2. Insert the 4 screws through the front prop
washer, followed by the propeller, spinner
backplate, rear prop washer* and fi nally
thread them into the prop driver.
4. While using a secure method to hold the
propeller and drill guide (we recommend a
drill press and clamp), drill the fi rst hole (order
does not matter). Drill carefully and take your
time. The more precisely you drill the propeller,
the better the fi tment of the bolts. If drilling a
carbon-fi ber propeller, pull the bit out every
few seconds to clear the hole of any material
and allow the bit to cool. Drilling through
carbon fi ber is tough on drill bits and takes
longer to complete than wood or plastic.

5. Before drilling any more holes, take a propeller
bolt and place it in the newly created hole. This
will help keep the drill guide aligned and keep it
from rotating when drilling the other holes.
6. Drill the rest of the holes.
7. Remove the drill guide.
8. Use a chamfering tool to deburr the holes on
each side of the propeller.
3. Begin to tighten all 4 screws until they are all
hand-tight.
4. Tighten all screws with the included 4mm
L-wrench in a clockwise circle until all screws
are tight.
5. Install the spinner cone. Make sure the spinner
cone is not touching the propeller. Trim the
propeller opening if necessary.
6. Tighten the spinner screw to secure the
spinner cone.
*The rear prop washer is optional. It should
always be used for additional bearing area
when using a wooden propeller without a
spinner. Removing it will reduce the engine
length by 5mm.
