Measuring the Transom Angle
Plumb 
NOTE: It is important to take your measurement in the figure showing Measuring the Transom Angle, from exactly 12 inches down from the top of the transom.
2. Place the two ratchets, one on either side of the transducer knuckle, |

so that the beads on each ratchet line up with the desired position |
number on the knuckle. If you are setting the ratchets at position 1, |

the beads on each ratchet will line up with the rib on the transducer |
knuckle to form one continuous line on the assembly. |
NOTE: The ratchets are keyed; make sure that the square teeth on each |
ratchet face the square teeth on the transducer knuckle, and the triangular |
teeth face outward. |
Hold the ratchets on the transducer knuckle with one hand and fit the |
pivot arm over them until it snaps into place with the other hand. |
Refer to the illustration. |
