* Due to combination of a boat type and an engine
type, the mount height of outboard motor varies.
Therefore, the complete information is impossible
to describe here.
For further information, see the instruction issued
by boat manufacturer, or ask to the manufacturer.
3. When the outboard motor mount position
has determined, mark the 4 symmetrical
mount hole positions onto the boat transom.
Make the mount holes of 13 mm (0.5 in.)
vertically on the marking points.
