No Access Underneath)

Stem Mounting with Existing 1" - 14 Thread Stem

Follow these steps to stem mount the GPS receiver:

1. If you have an Existing stem for mounting the GPS receiver, precede to step 2. Determine the best location to mount your GPS receiver. You should also be within 20' feet of the GPS display as routed through your boat's wiring channels. Preplan and test this routing 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.

2. If you have easy access to the top area of the stem, screw on the receiver base to the stem first. 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.

2a.

If you do not have easy access to the top area of the stem, assemble the receiver and base first. Attach the GPS receiver to its base using the #6 -

¹⁄₄

" screws (Figure

2). De-burr the pipe edges to reduce cable abrasion.

3. Use electrical tape to secure the DGPS pigtail to the cable as shown (Figure 3).

4. Route the GPS receiver’s cable through the stem and continue with the planned route decided on in step 1.

5. Attach the GPS receiver to its base using the #6 -

¹⁄₄

" screws.

5a. After routing the cable to the control head, screw the receiver

assembly on to the stem.

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

To optimize performance of the GPS receiver, mount it in an area that has full exposure to the sky. The effective area of reception is 10° above the horizon. Different circumstances determine the mounting method appropriate for your GPS receiver.

Under Location Access

Follow these steps to deck mount the GPS receiver when routing the cable down through the mounting location:

1. Determine the best location, then test route the 20' (6 m) cable from mounting location to the control head .

2. Mark the mounting location and drill a

³⁄₄

" (19 mm)

hole for the cable and cable plug.

3. With the cable routed, center the receiver over the cable hole. Mark the two mounting holes with a pencil or awl.

4. Move the receiver to the side and drill two pilot holes using a

⁵⁄₃₂

" (3.6mm) bit.

5. Align the GPS receiver's screw holes over the pilot screw holes (Figure 4) and attach with the #6 -

³⁄₄

" Phillips head screws. Hand tighten only.

Note: If the mounting surface is thin and made of a lighter material, a backing material may be needed below the mounting surface.

No Access Under Mounting Location

Follow these steps to deck mount the GPS receiver in a situation where you must route the cable to the side because there is no space for a cable underneath the mounting location.

1. Determine the best location, then test route the 20' (6 m) cable from the mounting location to control head.

2. After confirming the cable length is good, drill

³⁄₄

" (19mm) holes as needed to route the cable from the receiver to the control head. Secure the DGPS pigtail with electrical tape, (Figure 3) and route the cable.

3. If the GPS receiver is visible when mounted you may wish to orient the logo for aesthetic reasons. The physical orientation should be level with the horizon and high enough to view 360° of the sky unobstructed.

4. The GPS receiver has two wire routing notches. Use the cable notch closest to the intended cable route.

5. With the cable routed, position the GPS receiver in the planned mounting location and mark the mounting holes with a pencil or awl.

6. Move the GPS receiver to the side and drill the two

⁵⁄₃₂

" (4mm) pilot holes.

7. Align the GPS receiver's screw holes over the pilot screw holes (Figure 5)

and attach with the #6 -

³⁄₄

" Phillips head screws. Hand tighten.

Finish Routing the Cable and Check operation

1. Secure the cable along its path to the control head as needed with cable ties.

2. Plug in the GPS receiver cable to the control head, power on the control head and follow your operation sheet for the control head to confirm a good installation.
