9. Adjust the front engine mounts until they rest on the boat stringers.
10. Set the engine on the boat stringers.
11. After the alignment is set, turn the front mount adjusting nuts two full turns up.
NOTE: This compensates for the softer front mount when weight is applied.
12. Relieve the hoist tension entirely and fasten both mounts to the boat stringer using the appropriate hardware.
13. Disconnect the sling from the engine lifting eyes.
IMPORTANT: Alignment tools from other manufacturers may cause improper alignment and damage to the gimbal bearing
or engine coupler. Use only the Mercury alignment tool.
Improper use of the alignment tool may result in personal injury or damage to the gimbal bearing or engine coupler. Do not
operate the engine with the alignment tool installed. Do not attempt to force the alignment tool, raise or lower the engine with
the tool inserted in the gimbal bearing or engine coupler, or raise the engine mount bracket above the top of the engine
mount stud.
14. Attempt to insert the solid end of the alignment tool through the gimbal bearing and into the engine coupler splines.
