Outboard motor mounting
3-11
holes perpendicular to the surface of the
boat transom using a 13.0 mm (0.5 in) “a”
drill bit.
6. Apply sealant to the mounting holes, and
then secure the outboard motor using the
included mounting bolts “1” and “2”, small
washers “3”, large washers “4”, and nuts
“5”.
Make sure that there is no clearance be-
tween the surfaces of the boat transom and
the clamp brackets. Otherwise, the clamp
brackets or boat transom may be dam-
aged.
TIP:
The second hole from the top of each clamp
bracket is recommended for the upper mount-
ing bolt.
