ENGINE ALIGNMENT
CAUTION
Engine must be properly aligned, or vibration, noise
and damage to the transmission output shaft, oil seal,
and bearings may result.
IMPORTANT : Engine alignment MUST BE
RECHECKED with the boat in the water, fuel tanks full
and with a normal load on the boat. Engine must be
aligned so that the transmission and the propeller shaft
coupling center lines are aligned, and coupling faces
are parallel within 0.003 in. (0.07 mm). This applies
to installations with solid couplings, as well as fl exible
couplings.
1. Check the mating surfaces on the transmission
and the propeller shaft couplings. Make sure
they are clean and fl at (Figure 11-24).
Figure 11-24 Shaft Mating Surface Check
2. Center the propeller shaft in the shaft log as
follows: (Figure 11-25)
• Push down and then lift the propeller shaft as
far as it will move, then place the shaft in the
middle of the movement.
• Move the shaft to the port and then to the
starboard as far as the shaft will move,
then place the shaft in the middle of the
movement.
• With the propeller shaft in the middle of the
shaft log, align the engine to the shaft.

IMPORTANT: For PCM Power-Plus and Walters
V-Drive applications, adjust the engine and
transmission mounts to achieve alignment. The V-
Drive mounts are for support of the V-Drive unit and
are not used to achieve proper alignment.

V-DRIVE ALIGNMENT
The V-Drive support mounts must be removed before
performing the engine alignment.
• For the PCM V-Drive, loosen the trunnion bolt on
the mount, then remove the bolts used to attach
the mount to the CVD mounting bracket. Slide the
mount away from the bracket. Refer to Figure 11-
23.
• For the Walters V-Drive, loosen the trunnion bolt
on the mount, then remove the bolts used to
attach the mount to the V-Drive. Slide the mount
away from the V-Drive unit.

ENGINE ALIGNMENT
(2) Add four (4) quarts of new oil.
(3) Start and run the engine allowing suffi cient time for
the new oil to circulate and fi ll the new oil fi lter.
(4) Shut the engine off. Wait 5 minutes to allow the oil
to completely drain back to the pan. Check the oil
level with the dipstick and add the correct amount of
oil to fi ll to the “FULL” mark on the oil level dipstick.
Perform the Engine Alignment as outline in the following
steps. When you have completed the alignment you will
need to re-install the mounts onto the V-Drive unit. The
V-Drive mounts may need to be adjusted so there is no
tension on the mounting bolts as they are re-installed.
Re-tighten the trunnion bolts to complete the V-Drive
alignment.
