INSTALLATION AND PREDELIVERY
OUTBOARD INSTALLATION

Outboard Mounting
IMPORTANT: Some rigging components, such
as steering cables, must be fitted to the outboard
before the outboard is mounted to the transom.
Determine what equipment will be installed before
mounting.
Mounting Height
Boat performance depends on outboard mounting
height.
Generally, the anti-ventilation plate of the gear-
case should align with the bottom of the hull. Con-
ventional V-hulls often perform well with the anti-
ventilation plate approximately 1 in. (25 mm)
above the bottom of the hull.
Boats that exceed 50 MPH may benefit from
higher outboard heights. Consult the boat manu-
facturer for specific outboard mounting height
information for a particular hull.
Test outboard and boat performance at different
heights until the best performance is achieved.
IMPORTANT: Be sure that outboard water
pressure is not adversely affected by the mount-
ing height of the outboard.
Mounting Bolt Installation
IMPORTANT: Use a marine sealant rated for
above or below waterline use. RTV silicone is not
approved for below waterline use. Polyurethane
sealants are not easily removed and may damage
outboard or boat mounting surfaces.
Apply marine sealer under hex heads of bolts, on
the mounting plates, and to the bolt shanks.
Assemble transom mounting plates on mounting
bolts.
Install the mounting bolts through the transom
from the inside of the boat.
Position the square aluminum transom mounting
plates (when applicable) so the retainer holes are
horizontal.
Position hex head of bolt with flats toward holes in
the mounting plates. Install retainer over hex head
of the bolt and secure it with screws provided.
Install all washers and nuts. Tighten to a torque of
40 ft. lbs. (54 N·m).

WARNING
If either side of the transom deforms or
cracks when the bolts are tightened to
their recommended torque, the transom
construction may not be adequate or may
be deteriorated. Structural failure of the
transom could result in loss of boat control
and injury to the occupants.
