Make sure the release lever is disengaged when
measuring.
For drive shafts longer than 254 mm [10 in]:
• Insert the indicator line into the holes in the tool blades
using the pegs to hold the line tight.
• Install line in the tool so not to interfere with free
movement of the line.
Make sure the line is tight and does not sag.
The alignment tool blades overlap with the 254 mm [10 in]
drive shaft installation and no indicator line is necessary.
When installing the alignment tools, confirm that the
blades are not against each other, and the blades are
parallel to the ground.

Marine Applications
Drive shafts longer than 254 mm [10 in]:
• Check the horizontal alignment of the engine and pod.
Read the end of the tool where the line crosses the
degree scale.
Move the engine side to side to get as close to “0” as
possible.
Rotate both tools 180 degrees.
Confirm that the readings in this position are the same as
the previous test. If not, check the tool fit-up to the flanges
again.
Horizontal Alignment: 0 degrees ± 1/2 degree.
