OVERVIEW
MOUNTING THE OUTBOARD
The optimum mounting height is
determined by the boat/outboard
combination in addition to the
required use. Test runs at different
heights can be of assistance when
choosing the optimum mounting
height. For further information,
please contact the manufacturer.
!
CAUTION
Check the carrying capacity of the
boat, at rest and with maximum
load, during water testing.
Check that the static water level
on the outboard rig is low enough
to prevent water from entering
the powerhead when water rising
due to waves when the outboard
is not running.
Incorrect engine height can create
air born water spray while the
boat is cruising. If the outboard
is operated continuously in the
presence of airborne water spray,
enough water could enter the
engine through the intake opening
on the cowling and cause severe
engine damage.
Eliminate the cause of airborne
water spray.
The outboard should be mounted
in such a way that the boat is well
balanced. Otherwise it could be
difficult to steer. Mount the outboard
on the centerline (keel line) of the
boat.
Mounting height
The mounting height of the outboard
affects its efficiency and reliability. A
mounting that is too high might lead
to propeller ventilation, which will
reduce propulsion due to excessive
propeller slip. There is also a risk of
overheating the outboard due to the
water intakes of the cooling system
may not get enough water supply.
If the outboard mounting is too low,
the water resistance will increase
and thereby reduce the efficiency
and performance of the outboard.
In general, the outboard should be
mounted so that the anti-cavitation
plate is in alignment with the bottom
of the boat.
