Mercury 200 User Manual page 102

When first determining transom strength, use a dial torque wrench.
If the bolt or nut continues to turn without the torque reading on the
dial increasing, it is an indication that the transom is yielding. The
load area can be increased by using a larger washer or a transom
reinforcement plate.
NOTE: The inside holes on the transom reinforcement plate are
for the lower transom bolts and the outside holes are for the upper
transom bolts.
