CHECKING BOAT TRANSOM CONSTRUCTION
IMPORTANT: Determine the strength of the boat transom. The
outboard mounting locknuts and bolts should be able to hold
75 Nm (55 lb‑ft) of torque without the boat transom yielding or
cracking. If the boat transom yields or cracks under this torque,
the construction of the transom may not be adequate. The boat
transom must be strengthened or the load carrying area
increased.
a -
Transom yielding under bolt torque
b -
Transom cracking under bolt torque
