Humminbird 957C, 917C manual Stem Mounting with an Existing 1 14 Thread Stem, Abrasion

Stem Mounting with an Existing 1" - 14 Thread Stem

Follow these steps to stem mount the GPS receiver:

NOTE: If you have an existing stem for mounting the GPS receiver, proceed directly to step 2 of the following procedure.

1.Determine the best location to mount your GPS receiver. Preplan and test the cable routing to your control head before any drilling or cutting of your boat surfaces. If you have purchased hardware to stem mount your GPS receiver, follow the instructions included with that hardware to mount the stem (antenna pole).

NOTE: AS-EC10 10' extension cables are available from Humminbird® if your planned routing exceeds 20', (6 m). Maximum cable length, including extensions, should not exceed 50' (16 m).

NOTE: Remember to caulk or seal screw holes and drilled holes as needed to protect your boat from water damage.

12. Screw on the receiver base to the stem first, making sure that the stem pipe does

2 not protrude from the receiver base. This adds protection to the cable when pulling it through the pipe stem. In addition to this, de-burr the pipe edges to reduce cable

abrasion.

3.Use electrical tape to secure the NMEA pigtail to the cable as shown.

NOTE: Leave the NMEA pigtail secured to the cable unless needed. This will make removing the receiver easier.

4.Route the GPS receiver cable through the stem and continue with the planned route you chose in step 1.

5.Attach the GPS receiver to its base using the included #6 - 7/8" screws.
