PARTS REQUIRED
ENGINE MOUNTING
MOUNTING ENGINE TO MOTOR MOUNT
o
{2} Nylon Mounting Beams
o
{4} 3mm x 20mm Machine Screws
o
{4} 3mm x 25mm Machine Screws
o
{16}3mm Flat Washers
o
{8} 3mm Lock Nuts
o
1) Using a clamp or a vise, align the two
motor mount beams and clamp them together.
The beam halves are universal and the web-
bing should face the outside edges. See photo
# 17 below.

o
2) Mark the locations of the four engine
mounting holes on the beams using a pencil.
For the engine to align properly with the front
of the cowling, it is important that the front
edge of the engine's drive washer be 4-7/8”
forward from the rear edge of the mounting
beams.
o
3) When satisfied with the alignment of
the engine, remove the beams from the
clamp and drill 1/8” holes through the
mounting beams at the four engine mount-
ing hole locations.
o
4) Mount the engine to the mounting
beams using the four 3mm x 25mm machine
screws, eight 3mm flat washers, four 3mm lock
nuts. Tighten the screws and nuts completely.
If using an engine equipped with a re-
mote needle valve we recommend
mounting the needle valve to the engine prior
to installing the engine on the motor mount
beams.
ALIGNING THE MOTOR MOUNT
o
5) The engine is mounted sideways on the
firewall. Using a ruler and pen, measure and
draw a vertical centerline on the firewall.
o
6) Measure down from the top of the fu-
selage 1-1/2” and draw a horizontal line on
the firewall. See photo # 18 below.

o
7) With your engine still installed on the
motor mount beams, use a ruler and measure
the width between the predrilled mounting holes
in the motor mount. This distance will vary
depending on the brand and size of the engine
you have chosen. See photo # 19 below.

o
8) Divide the measurement found in step
# 7 in half. Measure this resulting distance
and draw one horizontal line above and be-
low the horizontal centerline.
o
9) On the two horizontal lines you just
drew, measure and place marks 3/8” to the
left and 1-1/4” to the right of the vertical
centerline (looking at the firewall). See photo
# 20 below.
