Engine Alignment
Engine alignment should be checked by your Authorized MerCruiser Dealer at specified intervals.
IMPORTANT: Engine alignment must be checked with boat in the water, fuel tanks filled and with a normal
load on board.
1
Engine must be aligned so that transmission and propeller shaft coupling centerlines are aligned and coupling
faces are parallel within .003 in. (.07mm).
After alignment is correct, coupler attaching screws and nuts must be torqued to 50 Ib. ft. (68 N
⋅
m).
2
Locking Nut - After alignment is correct, tighten securely.
3
Adjusting Nut - Turning nut clockwise lowers engine.
IMPORTANT: Both front mounts (or rear mounts) adjusting nuts must be turned equally to keep engine
level from side to side.
4
Clamping Screw(s) and Nut(s) - Loosen to allow sideways movement of engine. After alignment is correct, tight-
en securely.
NOTE: Some rear mounts have two clamping screws and nuts, on each side, others have only one clamping
screw and nut, on each side.
5
Maximum mount trunnion extension is 3/4 in. (20mm).
6
Tab Washer - After alignment is correct, bend tab against flat on adjust nut.
IMPORTANT: Be sure to recheck engine mount fasteners for adequate tightness after completing engine
alignment.
