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
