MOUNTING HEIGHT - SPORT MASTER GEARCASE
Improper installation of an outboard can result in serious injury or death. Do
not allow the upper outboard mounting bolts to be closer than 25 mm (1 in.)
from the top of the boat transom, not including any shims used to increase
transom mounting height. Never install the upper mounting bolts through
these shims.
Install the outboard to a height so that the distance between the underside of
transom bracket hooks and the bottom of the boat (measurement "c" in the
diagram below) falls between the recommended mounting height range.
Ensure that this measurement is to the actual bottom of the boat, not to any
steps or notches in the hull.
