Furuno GP-7000F installation manual Sensor position and transom angle

Adjusting

1.Using a straight edge, sight the underside of the sensor relative to the underside of the hull. The stern of the sensor should be 1-3 mm (1/16-1/8") below the bow of the sensor or parallel to the bottom of the hull.

Sensor position and transom angle

Note: Do not position the bow of the sensor lower than the stern because aeration will occur.

2.To adjust the sensor's angle relative to the hull, use the tapered plastic shim provided. If the bracket has been temporarily fastened to the transom, remove it. Key the shim in place on the back of the bracket.

2° - 10° transom angle (stepped transom and jet boats): Position the shim with the tapered end down.

19° - 22° transom angle (small aluminum and fiberglass boats): Position the shim with the tapered end up.

3.If the bracket has been temporarily fastened to the transom, remove it. Apply a marine sealant to the threads of the two #10 x 1-1/4" self tapping screws to prevent water seeping into the transom. Screw the bracket to the hull. Do not tighten the screws completely at this time.

4.Repeat step 1 to ensure that the angle of the sensor is correct.

Note: Do not position the sensor farther into the water than necessary to avoid increasing drag, spray, and water noise and reducing boat speed.
