Location: Rhinelander, Wisconsin | I worked as a field promotions rep for Lowrance for a few years, and can describe exactly what you need to do.
First, make sure the transducer is mounted on the starboard side of the boat. Make sure it is mounted to a lift strake that is part of the running bottom and will be in contact with the water when the boat is up on the pad. Your rig runs on a V Pad, so it's a bit different than other installations.
Lay a straight edge, preferably at least 4' long along the running bottom to the transducer mounting area on the strake you choose. Set the transducer on that stick, and mark the bracket holes allowing for some adjustment when tightening. Drill pilot holes, then a hole just smaller than the screw and counter sink a bit through the polyflake or gelcoat to avoid later crazing in the gel. Dip the screw tips in silicone sealant, and tighten down the bracket making sure the transducer is TIGHT to the straight edge.
Now tip the back of the transducer about 3 degrees, and it's part of the running bottom and will read at speeds to 70 MPH.
If you have the transducer deeper, several problems will result. Your boat handling at top end will suffer( and could suffer greatly), top end speed will suffer, a 'rooster tail' will be shooting water all over the place and there may be enough turbulence to get a bad reading anyway. |
