BOLTING MOTOR TO TRANSOM
Apply marine hull sealant to the mounting holes
and inside sealing surface of the large washer.
Use Hondabond HT (P/N 08718-0004) or
equivalent polymer sealant for below waterline
use. Adhesives should not be used, as they will
result in difficult motor removal or height
adjustment. Gel coat damage may also occur
when removing/adjusting the motor.
With the motor in place against the transom,
verify correct motor height. The motor can be
raised by using a lower set of mounting holes on
the bracket.
If the boat transom has molding that prevents the
outboard stern bracket from sitting flat against the
transom, add a spacer plate or contact the boat
manufacturer for information on how to remove
the molding.
Attach the motor with marine grade hardware.
Use washers under all bolts and nuts. Use
additional fender washers against the transom.
Use support plates as recommended by the hull
manufacturer.
Lubricate the mounting bolt threads with marine
grease prior to installing the mounting bolt nuts to
prevent thread galling and locknut insert damage.
Tighten the transom 12 mm hex nuts to the
specified torque, and secure with the jam nuts.
TORQUE:
54 N•m (40 lbf-ft)
Ensure at least one thread of the bolt is visible
beyond the nut when the fastener is tightened.
NOTICE
Do not use an air impact tool to tighten or loosen
the transom bolts. Using an air impact tool to
tighten or loosen the transom bolts can generate
enough heat to damage the bolt threads. The air
impact tool can also produce enough tightening
torque to damage the boat transom.
Do not scratch the transom bracket when
tightening the mounting bolts. Removing paint
promotes corrosion and leads to eventual failure
of the bracket.
Pay attention to the washers, support plates (if applicable), and boat transom as the
nuts are tightened. This is especially important on boats that are being repowered. If
the washers and/or support plates are drawn into the transom material, the transom
material is weakened and must be inspected and repaired as necessary before the
motor is installed.
If the transom is found to be soft, water penetration may have occurred and caused the
transom material to rot and weaken. Contact the boat manufacturer for boat repair
information as needed.
