3. Above 25 m.p.h. (40 km/h): Use "X" Dimension shown.
4. Above 50 m.p.h. (80 km/h): The "X" Dimension can be increased to improve perform-
ance in some applications, but pulling power (for skiing) will decrease. During testing,
"X" Dimension should be increased 1/2 in. (13mm) at a time until desired performance

In ALL applications where cooling water is supplied through the sterndrive unit to the
engine, extreme care should be taken when raising drive unit to ensure that the water
supply does not become aerated. Use a clear, water inlet hose to check incoming water for
aeration. Monitor engine temperature gauge to ensure engine does not overheat.
In applications where cooling water is supplied to the engine by a fitting through the
hull or transom, the sterndrive height will not cause cooling water aeration.
IMPORTANT: Damage to MerCruiser products caused by too high of an installed
height will not be covered by MerCruiser warranty.
