NOTE: It is often necessary to make several incremental transducer adjustmentsbefore optimum high speed performance is achieved. Due to the wide variety of boat hulls, however, it is not always possible to obtain high speed depth readings.
6.Once you have reached a consistently good sonar signal at the desired speeds, you are ready to lock down the transducer settings. Remove the transducer from the bracket (after noting where the ratchets are assembled), then
7.Drill the third mounting hole, using a 5/32” drill bit. Use a marine- grade silicone sealant to fill all three drilled mounting holes, especially if the holes penetrated the transom wall.
NOTE: On fiberglass hulls, it is best to use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating.
