3.Continue to hold the bracket on the transom of
the boat, and use a pencilor marker to mark
whereto drill the two mountingholes. Mark the
drillholes near the top of eachslot, making sure
that your markis centered in the slot (see the
illustration Using the Mounting Bracket to
Markthe Initial DrillHoles).
4.Make sure thatthe drill bit is perpendicular to the
actualsurfaceof the transom, NOT parallelto the
ground,beforeyou drill.Using a 5/32” bit, drillthe
twoholes only to a depthof approximately 1”.
NOTE:On fiberglass hulls, it is best to use progressively larger drill bits to reduce
thechance of chipping or flaking the outer coating.
3. Assembling the Transducerand Initial Mounting
Inthis procedure,you will assemblethe transducerusing the hardwareprovided,
thenmount it and makeadjustments to its positionwithout locking itin place.
NOTE:You will initially assemblethe transducer and the pivot arm by matching the
tworatchets to a numberedposition on the transducer knuckle. Further adjustments
maybe necessary.
1a. If youalready know your transomangle, refer to the chart belowfor the
initialposition to use to set the ratchets.If your transom is angledat 14
degrees(a common transomangle for many boats) use position1 for the
ratchets.In either case, go to step 2. If you donot know your transom
angle,go to step 1b.
or...
NOTE:
The third hole should not be drilled until
theangle and height of the transducer is finalized,
whichyou will not do until a later procedure.
