Mercury GO BOLDLY 25 EFI Operation, Maintenance And Installation Manual page 42

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.
