On boats with stepped hulls, it may be possible to mount the
transducer on the step. Mounting the transducer on the transom
behind a step will reduce or make impossible high speed operation.
This area of the transom, behind a step, will not be in contact with the
water at high speed.
If the boat is trailered do not mount the transducer close to where
trailer bunks or rollers will impact with the transducer during loading
and unloading of the boat.
Once you have identified the location, use the mounting template on
page 4. This template locates the two mounting holes which must be
drilled. Note that there are two sets of holes, one for a fiberglass hull
and another set for an aluminum hull.
Hold the template on the transom of the boat in the location you
have selected. Align the template vertically.
Using a pencil or punch, mark the two mounting holes onto the
transom. Use the mounting bracket itself to confirm your marks.
Using a
⁵⁄₃₂
"(4mm)
bit, drill the holes to a depth of approximately 1".
On fiberglass hulls, it is best to use progressively larger drill bits to
reduce the chance of chipping or flaking the outer coating.
The third hole should not be drilled until the angle and height of
the transducer is finalized.
Use a silicone sealant to fill the drilled holes, especially if the holes
penetrated the transom wall.
Attach the transducer body to the pivot as shown in the illustration at
right, using the Pivot bolt to couple the transducer ears to the
mounting bracket. The toothed washers must fit on the inside of the
transducer ears, between the pivot and the ears.
Use a #3 Phillips screw diver to hand tighten the transducer
assembly. Do not fully tighten the assembly at this time.
Align the transducer assembly with the drilled holes in the transom.
Mount the transducer assembly to the transom using two wood
screws and washers as shown. Do not fully tighten the mounting
screws at this time.
