❑ While holding the engine firmly in place, use a pencil

to mark the locations of the four engine mounting screws

onto the engine mount beams.

❑ Remove the engine and set it aside.

❑ Using a drill with a 1/8" drill bit, carefully drill a pilot hole through the engine mount beams at each of the four

locations you marked. Make sure to drill straight down through the beams and not at an angle.

Because of the consistency of the engine mount beams, it's best to drill pilot holes before drilling the larger holes.

This will prevent the drill from "creeping" and distorting the holes.

❑ Set the engine back into place and realign it. Double-check to ensure that the holes in the engine mounting lugs still

line up with the pilot holes in the beams.

❑ Remove the engine and set it aside.

❑ Using a drill with an 11/64" drill bit, enlarge the four pilot holes in the engine mount beams.

❑ Install the engine using four 4mm x 25mm socket-cap

screws, eight 4mm flat washers and four 4mm nylon-insert

hex nuts. Tighten the hex nuts and screws firmly to secure

the engine in place.

Before marking and drilling the holes for the engine mounting screws in the next few procedures, it's very important to

verify that the engine's thrust washer is 5-5/8" away from the firewall. This will ensure that the front of the cowling

lines up properly when it is installed later. This measurement is universal for all engines, both two and four strokes.
