Engine Alignment

Proper alignment between the engine and transom assembly is essential to avoid U‑joint knocking and prevent failure of the
engine coupler and U‑joint shaft splines. A Quicksilver engine alignment tool is required for this procedure. The complete
alignment procedure is outlined in the installation manuals. Refer to the installation manual for the steps. Important elements
are outlined following:
NOTICE

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.
