❏ 1. Draw a vertical line on the firewall using the embossed

lines as a guide. Note: This line is offset to the left side of the

fuse so that the spinner will be on the center-line of the fuse.

❏ 2. Trim the spreader bars from both halves of the engine

mount. Mount the engine mount to the firewall with four

8-32 x 1" [25mm] SHCS, #8 flat washers and #8 lock washers,

but do not fully tighten the bolts.

❏ 3. Adjust the width of the mount to fit the engine. Center

the molded-in “tick” marks on the engine mount equally to

the left and right of the vertical line on the firewall. Tighten

the mounting bolts.

❏ 4. Place the back plate of the spinner on the engine.

Note: Depending on your engine choice, it may be

necessary to enlarge the hole in the back plate.

❏ 5. Use small clamps or another method to temporarily

secure the engine to the mount with the back plate of the

spinner 5-7/8" [150mm] from the firewall. Use the Great

Planes Dead Center

Engine Mount Hole Locator

(GPMR8130) or your preferred method to mark the engine

mount holes onto the engine mount.

❏ 6. Remove the engine from the mount. Drill #29 holes

through the mount at the marks you made. Tap 8-32 threads

into the mount. Mount the engine to the mount with four

8-32 x 3/4" [19mm] SHCS, #8 flat washers and #8 lock washers.

❏ 1. Use epoxy to glue the four 3/8" x 3/4" x 3/4"

[9.5 x 19 x 19mm] maple cowl mounting blocks to the firewall

in approximately the locations shown.
