Procedure
Outboard Transom Installation
1. Apply marine sealer to the shanks of the mounting 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 Mercury Marine transom drilling fixture position may be required to ensure proper clearance. 2. Fasten the outboard with the correct mounting hardware and 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 must not contact the shank of the bolt.
