Procedure
Outboard Installation
1. Apply marine sealer to the shanks of the bolts, not to the threads. WARNING: Clearance must be maintained between the vessel transom and the outboard transom bracket relief radius area. Failure to maintain clearance may damage the transom bracket and cause it to fail. Adjustments to the position of the Mercury Marine transom drilling fixture may be required to ensure proper clearance of the transom bracket relief radius area. 2. Fasten the outboard with the correct mounting hardware. Tighten the locknuts to the specified torque. WARNING: Ensure that a minimum of two full threads of the mounting bolts extend beyond the locknut after tightening. The locknut must be drawn tight while still engaging the bolt threads and not contacting the shank of the bolt.
