Step 2: Installing the Engine Mount Beams

❑ Using a drill with an 11/64" drill bit, drill a hole through

the firewall at each of the four intersecting lines.

❑ Install the engine mount beams using four 4mm x 30mm

socket-cap screws, four 4mm flat washers and four 4mm blind

nuts. Tighten the screws firmly to draw the blind nuts into

the back of the firewall.

☞

Notice that the engine mount beams are mounted on their

side so that the engine will be installed on its side.

Step 3: Aligning & Installing the Engine

❑ Set the engine on the engine mount beams. Using a

ruler, measure the distance from the front of the firewall to

the front of your engine's thrust washer. Adjust the depth

of the engine so that the measurement is 5-5/8".

❑ Remove the engine mount beams from your engine and clean off any dried C/A from the engine mount beams and the

bottom of the engine mounting lugs using a modeling knife.

IMPORTANT

If you are using a short engine like a .61 two stroke or a new-generation .91 two stroke in a sixty-one size case, then you

should drill and install the plywood spacer (D23) between the motor mount beams and the firewall in the next procedure.

WARNING

Do not measure out from the plywood spacer. Make sure you measure out from the firewall.
